GN 331 and 332 Tubular Handles with Power Switching Function

2012-01-25T11:30:00.000-06:00

GN 331

Today's featured new products are our series GN 331 and 332 Tubular Handles with Power Function, available in metric sizes. These RoHS-compliant tubular handles are designed for unlocking safety tumblers in sliding or rotating doors.

Switches, pushbuttons and LEDs that are normally installed in external operating panels, are here integrated in an attractively shaped tubular handle. The same hand that unlocks the tumbler by pushing the release button with the thumb, can be used to open the door. Versions are offered with one or two buttons and with or without emergency stop. By integrating functions such as emergency stop, start, release, reset and LED status display, this handle allows the machine to be monitored and operated directly at the door or gate. GN 331 handles save mounting and installation work, and are attractively and ergonomically designed--switching and operating functions are located precisely where they are needed.

GN 332

GN 331 series handles have straight shanks, and GN 332 handles are angled. The handle tubing is aluminum and either textured matte black plastic powder-coated finish or natural color anodized. The handle shanks are zinc die cast with textured matte black plastic powder-coated finish. A set with caps in red, green and blue is supplied for every push button. Couplings for plug connectors (GN 331.1) with the appropriate cables are available for tubular handles with electrical switching function.

GN 418 Cam Point Screws and GN 418.1 Cam Point Levers

2012-01-10T09:17:00.000-06:00

GN 418

Today we're introducing to you our GN 418 Cam Point Screws and GN 418.1 Cam Point Levers in metric sizes. These RoHS compliant components are maintenance-free clamping elements designed for a wide variety of different uses and applications, including clamping flat or round workpieces, centric clamping in bore holes, and multiple clamping in tight spaces. They are stable, compact, and easy to use.

GN 418.1

The mode of function is identical for both: The screw head of the cam point screw is fitted with two cams: a radial clamping cam (with additional 30° chamfer) and an axial draw-down cam. The self-locking cam ensures that the clamping force is of the same magnitude in every angular position. The force components acting at the clamping point generate friction and a draw-down effect which presses the workpiece against a fixed-end stop. The thread and the 30° chamfer (if fitted) generate an additional draw-down effect.

Cam point screws are fitted with a hexagon head socket. The steel is case-hardened, zinc-plated and blue passivated. Cam point levers have a handle (with black plastic ball knob) connected to the cam point screw with a serration, allowing the suitable clamping position to be selected and the lever to be adjusted. Both the screw and the cam are case-hardened and burnished. Both right-hand and left-hand thread types are available.

J.W. Winco Parts for...Your Harmonica?

2011-11-17T08:27:00.000-06:00

We always love learning about unique applications for the standard machine components we sell, and this one is definitely interesting. German company Sonnenschein SLK makes a professional-quality neckholder for harmonicas (aka harps) for hands-free playing. Our GN 927 Clamping Levers with Eccentrical Cam are a key component in these holders, which we are happy to now have available in inch as well as metric sizes.

The easy clamping and releasing feature of these clamping levers is what makes them perfect for this application. A flick of the fingers allows the user to unclamp the brackets and adjust the harmonica's position to the perfect level. In contrast to a clamping operation utilizing threads, these levers permit torque-free clamping. The lever has been designed to insure that its movement cannot exceed the maximum clamping position.

You can see more clearly in this diagram where the pair of GN 927's are employed in the "harp-rack."

GN 927 levers are RoHS compliant, with zinc die cast handles and a matte black plastic coated, abrasion-proof epoxy resin finish. Components are zinc plated, blue passivated steel. They are available with two types of technopolymer contact plates: a fixed version, or an adjustable contact plate, with which the distance between the eccentrical cam and the contact surface is adjustable by means of a fine threaded knurled nut.

If you're interested in purchasing the harmonica holder itself, complete information is available from the manufacturer on their website.

We appreciate that a component we offer is helping people make beautiful music!

GN 722.2 Square Spring Latches with Flange

2011-09-23T07:46:00.000-06:00

Today we're introducing you to our GN 722.2 Square Spring Latches with Flange for Surface Mounting.

These spring latches are designed for use in applications where less precise positioning/locking is required. The dimensional tolerances are therefore chosen for cost-effective production, while insuring that functional safety is guaranteed when exposed to dirty or dusty environments. They provide high dynamic and static strength and can be loaded from any direction with approved safety (safety factor 4).

This type of spring latch is used when the indexing pin needs to be retracted. The indexing pin retracts by turning the latch up the cam slope by 180°. A lock notch will hold the latch in both positions. The flange has two holes for mounting that can accommodate metric DIN 933/931 hex cap screws or DIN 912 socket cap screws. Equivalent inch size screws may potentially also be used for mounting the latch.

The guide body is steel, precision cast, with either a zinc plated finish or black textured finish. The precision cast latch and the plunger pin are zinc plated, blue passivated steel. The spring latches are available in versions with the latch position either right-angled or parallel to the mounting holes, and are RoHS compliant.

Our GN 421-NI Knobs and the BMW Motorcycle Solution

2011-08-10T07:50:00.001-06:00

Those crafty customers of ours...they're forever developing nifty solutions for their applications using J.W. Winco components.

This week we discovered one on a forum for owners of BMW K1600 motorcycles. It seems that sometimes it's desirable to remove the rear seat on these bikes, but they are designed in a way that requires employing a screwdriver...a technique the poster on the forum termed a "PITA," or pain in the you-know-where.

He found that a pair of our GN 421-NI Hollow Knurled Knobs could be swapped in (part ID 5N25P02), resulting in a quick and easy way to take the seat on and off. These metric-sized knobs are indeed an ideal solution for this application. The knurling on the nylon plastic knob provides for a good grip even when wet. And the stainless steel stud prevents corrosion from salt and any other chemicals a rider encounters on the road.

One more ideal aspect of these knobs: while they are excellent quality, they're also economically priced.

It seems a lot of forum readers agree with the poster that our GN 421-NI's are the perfect solution, because they've been buying them ever since the post appeared! Seems to us at J.W. Winco that the engineers at BMW ought to take note and spec this great component into future designs....

Steel Locking Plungers with Push-Push Locking Mechanism

2011-07-13T08:31:00.001-06:00

Today we're showing off our new GN 514 Steel Locking Plungers with Push-Push Locking Mechanism, in metric sizes.

The indexing pin in this locking plunger is moved by means of a spring-operated cardioid curve. By simply pressing the operating button, this cardioid mechanism causes the indexing pin to extend and retract (push-push locking mechanism). This function is similar to that used in a ball point pen. Please note that the indexing pin cannot absorb any axial foces and that it retracts virtually by spring action; the indexing pin must therefore remain free and easy to move.

The body of these RoHS compliant locking plungers is made of nitrided steel with a blackened finish. The knob is matte black technopolymer plastic (Polyamide PA), and the optional metric lock nut, ISO 8675, is steel with a blackened finish. Installation can be done with spacer bushings (purchased separately) instead of the lock nut.

Please see our full line of spring, ball and indexing plungers in Section 10 of our online catalog.

Retaining Magnet Assemblies

2010-10-20T13:52:00.000-06:00

We're delighted to announce a brand new product line: metric-sized Retaining Magnet Assemblies. We're offering 18 different types of magnet assemblies, to accommodate any application.

The use of retaining magnet assemblies is a simple solution for no-wear magnetic holding of an object. Due to their structure, these magnet assemblies have only one magnetic pulling force level. The full magnetic force is focused directly onto the adhesive surface by means of iron magnetic poles. The spatial effect of the magnetic field is limited by shielded systems, so that surrounding objects are not magnetized.

Among the types of magnet assemblies we offer are flat gripper types, like the GN 50.1 Disc-Shaped without Thread in steel, which you see to the right...

Rod gripper types, like this GN 54.1 Rod-Shaped with Smooth Finish, in brass...

Button-types, like the GN 60 in steel...

and U-Magnets, like the GN 62, also in steel.

Within the assemblies, the magnets themselves come in four materials: hard ferrite SrFe (HF type), samarium and cobalt combination AlNiCo (SC type), neodymium, iron and boron version NdFeB (ND type), and aluminum, nickel and cobalt combination AlNiCo (AN type).

They also come in a variety of sizes, threads, and finishes, and are designed to accommodate different mounting requirements. Magnet assemblies also provide a variety of levels of pulling force.

To view all the details on our 18 series of retaining magnets, along with pricing, online buying, and (coming soon) CAD models, visit Section 11 of our website catalog. Or contact a Technical Sales Associate at 800-877-8351 to discuss your application requirements.

J.W. Winco Wins "How I Got My Business Out of Hot Water" Challenge

2010-07-08T08:08:00.000-06:00

We’re proud to report that our company won second prize in a competition from the Independent Business Association of Wisconsin (IBAW) and Reliable Water Services LLC. The three winners of the “How I Got My Business Out of Hot Water” business challenge were announced at the IBAW monthly meeting on June 18, 2010.

The winning essay was written by your humble blogger, and described how Upper Management at J.W.Winco reacted when the economy and the industrial manufacturing industry declined in 2008. “Until then, our business had been growing steadily. In fact, we just built a 40 percent expansion and redesign of our facility in New Berlin,” the essay states. “Switching gears so suddenly from a growth outlook to survival mode was a huge challenge.”

The essay described methods we used to ride out the storm, including upper management salary reductions, using employees for tasks previously outsourced, finding more cost-effective shipping, and chipping away at operating costs. It also explained the lessons learned during the recession, which we continue to apply now that the crisis is over.

“We had new focus on things like return on investment, efficiency, cooperation, and enthusiasm for selling,” explains the essay. “We know now that we have to apply consistent effort to constant improvement, and never assume the status quo is good enough.”

If you'd like to read the entire essay, it is available on the Reliable Water Services website here.

Wisconsin companies Flexo-Graphics LLC (Butler) took first prize, and Two Men and a Truck (Madison) took third prize.

GN 924.3 Two-Spoked Flat-Faced Handwheels with Retractable Handle

2010-06-30T12:13:00.000-06:00

We previously posted about our new flat-faced handwheels. In this new line, we offer GN 924.3 Two-Spoked Flat-Faced Handwheels with Retractable Handle, a variation that can be ideal for applications where you don't want the handwheel's cranking handle to get in the way.

These handwheels are RoHS compliant and come in both inch and metric sizes. They are distinguished by their modern, flat-faced design and recessed handles. The handwheel body is pressure die-cast aluminum with a powder coated matte black pebble finish or a silver textured finish. Rim is concentric and square to bore. The locking retractable handle has a zinc plated steel threaded spindle, a black oxide steel retracting mechanism and matte black nylon plastic hand piece. The removable plastic cover shrouds the assembly hardware such as screws and countersunk washers, as well as the shaft end.

When the handle is pulled upward into operating position, it locks into a conical recess. To fold it down, draw the handle back from the recess and lay it down into the neutral position inside the handwheel spoke. A compression spring holds the handle in both positions.

Check out our huge selection of handwheels in Section 5 of our online catalog.

GN 918.5 Stainless Steel Eccentrical Cam Units

2010-06-25T14:37:00.000-06:00

Sharing with you another of our newer products, GN 918.5 Stainless Steel Eccentrical Cam Units. The metric sized cam units are RoHS compliant. The cam is chemically nickel-plated stainless steel. Hexagon threaded bolt and washer are tempered stainless steel, chemically nickel-plated. The ball lever handle is matte shot blasted stainless steel with a black phenolic plastic ball knob.

These cam units have a relatively long movement and high clamping force, providing rapid and safe clamping and release. The cam offers the advantage of the clamping force acting over the entire clamping area (i.e., maintains the clamping force in all angular positions). The lever handle is linked to the cam via mating serrations which allow the positioning of the lever in a preferred position. The eccentrical cam can also be used with T-slot nuts on machine beds, or as stepless adjustable end stops. If the washer is removed, the eccentrical cam can be clamped directly to its support.

See our entire selection of eccentrical cam units and cam levers in Section 11 of our online catalog.

GN 350.1 Short Model Leveling Sets

2010-06-17T10:04:00.000-06:00

Please welcome to the blog another new product: GN 350.1 Short Model Leveling Sets.

These RoHS-compliant, metric sized leveling sets are made of zinc plated, blue passivated steel, and consist of a threaded upper sleeve and a tapped lower sleeve. They are used for leveling, adjusting, and linking operations of smaller dimensioned components.

The fine thread allows precise, stepless setting and locking using a DIN 1810A hook wrench (available separately). An anti-rotation disk serves also as a height limiter for the maximum height. Normally this screw is permanently and securely locked by the static load created when the mounting screw is tightened. If this is not sufficient, the use of a locknut is recommended.

Check out our other leveling sets in our online catalog, Section 11 - Jig, Fixture and Fastening Components.

Lifting and Lashing Products from RUD

2010-05-25T14:36:00.002-06:00

We just recently introduced a unique and superb quality series of lifting and lashing products, manufactured by RUD of Germany. If safety is your priority, these components are unsurpassed and should definitely be your choice!

More than 30 years ago RUD secured its first patents, for both bolt-on and weldable versions of secure lifting eyes. Frequently occurring industrial accidents (caused by broken DIN 580 eyebolts or self-made weld-on sheet metal or wire constructions) had demonstrated the urgency of design changes.

Since the first series production of its weldable and bolt-on load rings, over 100,000 RUD-manufactured load rings have been sold. Although these products have proved themselves under the toughest conditions, RUD continues to pursue creating even safer and more reliable products. RUD has updated its original types by increasing the working load limit up to 50 metric tons for weldable and up to 150 metric tons for the boltable types.

Until recently, the design of lifting points has not seriously considered the extent to which loads have to be turned and twisted during the handling process. With these turning movements, the loads can be damaged and/or the lifting system can be considerably overloaded. Properly torqued safety hoist rings are ideal for the needs of mold and die manufacturers. When a mold or die must be flipped, the lifting points need to swivel and pivot at the same time.

Hoist rings from RUD use a body, bushing and graphite-based lubricant to allow them to swivel, and an integrated oval or round eye to allow for pivoting. Another lifting point design uses ball bearings in the body to allow for swiveling and an integrated eye to allow for pivoting.

Why are RUD lifting points pink? The distinct florescent pink powder coating in not only highly visible, it is a heat indicator. It permanently changes color at increased temperatures. If chain reaches temperatures above 400°C, the color changes to a deep black, indicating that the chain has been over-heated.

These and other characteristics make these products superior to the competition. We are delighted to offer five series of load rings, lifting eye bolts and lifting eye nuts on our website (see Section 11, scroll to bottom, and look for pink!). We also offer the complete line of RUD products upon request. To learn more, contact us at 1-800-877-8351.

Cleverness with Levers

2010-04-21T12:59:00.006-06:00

At J.W. Winco we’re always tickled when we learn someone has found a creative use for our machine components. Recently we spotted a forum post on the site Cinema5D.com, which is directed at filmmakers.

Cinematographer Hal Davey shared his clever use of our WN 300 plastic adjustable levers (specifically part number 6T16F36O) to create adjustable “legs” for a camera slider rail. Hal posted:

“These neat looking legs are glass filled nylon adjustable Levers from J.W. Winco, Inc. They are available in black or orange for $5.95 each including shipping!

“I had to tap the rail for 3/8" x 16 threads. You screw the lever into the rail (3/8" X 16 thread) tightly. Then you can pull the lever outwards against a spring to position the lever into the position you desire. When you release the lever it locks into a toothed ring to hold the position of the lever. The lever shown is the longest available in 3/8" X 16 stud (also available in metric threads).

“You need a nylon spacer 3/4" (about 19mm) by 7/64" thick. The spacer is needed as there is a 1/4" unthreaded shoulder on the lever stud. You should be able to find the spacers at your local hardware store.”

Hal went on to answer a few questions, explaining the appropriateness of our part for this application. The levers are sturdy enough to easily handle the weight of Hal’s 1200 mm rail along with the camera, carriage and mount. The nylon levers won’t mar floors, and they rotate easily out of the way. Best of all, he points out that this solution saved him $200 over the cost of the traditional legs you see here!

Our WN 300 levers have handles made of glass fiber reinforced thermoplastic, and their inserts, screws and springs are made of black oxide finish steel. For complete information, see the WN 300 page of our online catalog.

Nice work, Hal!

Leadership in Wind Energy

2010-03-05T23:57:00.000-06:00

The great thing about our business at J.W. Winco is that we get to sell components to every possible industry. When a new industry rises to the fore, odds are good that industry will need our parts. It can be quite exciting!

A great illustration of this is that recent upstart, windpower. What only a few years ago was a novelty is now becoming a valid and essential part of the world's energy resources. And a key component to wind turbines is something so simple it has been around since the earliest years of the Industrial Age: the washer. Well, that simplicity can be deceptive: when you're talking about something as large and carefully engineered as a wind turbine, you're going to need washers of excellent design and quality.

The February issue of the new Windpower Engineering magazine showcases several companies for their "Leadership in Wind Energy." J.W. Winco was fortunate to be included in this competition (you can vote for us here on the Windpower Engineering Web site). As part of our feature we presented some of our most popular series of washers appropriate to the windpower industry, which you see pictured here.

From top to bottom, here are our DIN 6319 C and DIN 6319 D Metric Spherical Seat and Dished Washers, our GN 6339 Heavy Duty Washers, and our GN 350.3 Spherical Leveling Washers. Click on those links to find out all the technical information on these components.

These are just some of inch and metric size, high quality washers we offer. And we're happy to provide washers to everyone from the manufacturer of high tech wind turbines to the Boy Scout making a Pine Derby car. You can view the whole selection in Section 11 of our online catalog, Jig Fixture and Fastening Components.

2010-02-16T13:42:00.003-06:00

Back in October we talked about our very cool Pneumatic Power Clamps manufactured by Misati, S.L. (If you missed that post, it's here.) Since that report, we have added another version of these patented, smaller profile, high clamping force, super-efficient clamps.

The MN 140 series of fastening clamps differs from other models in that the two arms exert an outward force from the center. The RoHS-compliant, metric size clamps are made of C45 hardened steel with a black oxide finish. They have a maximum pressure of 10 bar and work pressure of 6 bar.

As with the other types of Misati power clamps in J.W. Winco’s line, they can be combined with a complete selection of accessories to accommodate any application. Check out the entire line in Section 15 of our online catalog.

GN 923 and 924 Flat-Faced Aluminum Handwheels

2010-01-29T08:34:00.005-06:00

We're pretty excited about our new series GN 923 and GN 924 Flat-Faced Aluminum Handwheels, a new modern design that has us quite impressed.

GN 923 handwheels are solid disk, while GN 924 are two-spoked. Both types are available with or without revolving handles, as well as in versions with recessed locking retractable handles and recessed safety retractable handles. All types are RoHS compliant and come in both inch and metric sizes.

These handwheels are distinguished by their modern, flat-faced design and their recessed handles. The handwheel body is pressure die-cast aluminum with powder coated matte black pebble finish or silver textured finish. Rim is concentric and square to bore. The revolving handle is matte black nylon plastic hand piece with zinc plated steel threaded spindle. The removable plastic cover shrouds the assembly hardware such as screws and countersunk washers, as well as the shaft end.

How to Punch a Square Hole in Sheet Metal

2010-01-19T14:03:00.004-06:00

My weekly googlings recently turned up a fun reference to J.W. Winco. Apparently our website was used as a source for an eHow article on punching square holes in sheet metal.

The key to the whole business, as so often in life, is having the right tool. If you happen to have a punch press and a square punch and die set, you’re good to go. But if you only need to punch a couple of holes on the rare occasion, that’s a prohibitively expensive investment.

The answer is our series GN 123 sheet metal punch, pictured here. This hardened steel punch is capable of penetrating sheet metal up to 2 mm thick. GN 123 punches are available in two sizes, to create square holes that will accommodate 14 or 22 mm.

We offer this tool in conjunction for use in installing our door locks GN 115, GN 115.1 and GN 119. But as the eHow article explains, some automotive parts require a square pass-through hole in either a sheet metal panel or other metal component.

After marking the center of the spot where you want the hole (using black marker on a piece of masking tape), you’ll need to drill a pilot hole. The mandrel of the punching tool is inserted in the pilot hole. You’ll use a ratchet wrench with the punch to drive the square die through the sheet metal.

Complete instructions are here.

GN 743.6 Metric Sized ATEX Explosive Protective Fluid Level Sight Glasses

2010-01-13T09:27:00.007-06:00

Today we're showing off our new series GN 743.6 Metric Sized ATEX Explosive Protective Fluid Level Sight Glasses.

The RoHS-compliant sight glasses have a body of turned aluminum, bright finish, an ESG scratch-proof glass sight glass, a stainless steel retaining ring, and a seal of FPM rubber (Viton®).

These sight glasses are suitable for use in explosion risk environments, and comply with European 94/9/EG guidelines. They are sealed with an O-ring on the periphery and not on the face edge of the glass. Leak tightness is therefore not affected by axial pressures. The seal is housed in a groove and therefore cannot be lost. Meanwhile, this groove prevents the seal from being extruded when the sight glass is tightened. The location of this seal also allows the use of a softer Elastomer, guaranteeing better and easier sealing. Cold/heat resistance range is -20°C (-4°F) to 150°C (300°F).

To see more of our line of sight glasses, visit Section 12, Fluid Level Indicators and Components, in our online catalog.

GN 816 and 816.1 Steel Locking Plungers

2009-12-29T16:05:00.003-06:00

Here are our latest featured products, a pair of indexing plungers from our broad selection: our series GN 816 and GN 816.1 Steel Locking Plungers.

These plungers have a threaded body of zinc-plated, blue passivated steel, stainless steel plunger pin and spring, and zinc-plated steel lock nut. The knob and sleeve are technopolymer plastic (Polyamide PA), black matte finish, and are not removable. The plungers are RoHS compliant.

For the 816 version, in the rest position the pin of the plunger protrudes. To retract the pin, pull the knob up against the spring force to the final position and turn it 90° to lock the pin in the retracted position. For the 816.1 plunger, in normal position the pin is retracted. To make the pin protrude, push down to the final position and turn 90° to lock the pin. For both, a type with key is also offered. The key is required to move the plunger in the same manner as the knurled knob type. In this version, a cover sleeve provides additional security and safety from unauthorized removal of the locking plunger.

Revolutionary Fastening Clamps from Misati

2009-10-28T10:24:00.008-06:00

We wanted to share with you today a very special product line offered by J.W. Winco. Misati, S.L., an ISO 9001-certified company in Barcelona, Spain, has been supplying industrial clamps to the world since 1979, and we now distribute these remarkable clamps.

To the right you see an example of Misati clamps in use in an industrial application.

Creative thinking in the field of kinetics led to the development of these clamps, which are well suited to applications in a variety of industries, including assembly, verification, handling, and welding.

You see here an internal view of the double-effect pneumatic cylinder that achieves high-force clamping.

The advantage of the clamps’ new design is the ability to exert greater force with a smaller apparatus. The clamp has a double-effect pneumatic cylinder that transmits a turning movement to the clamping arm along the shaft. Thanks to the special shape of the oblong hole, the clamp exerts high force.

Meanwhile, the line offers a wide variety of standard accessories, which may be combined to suit any specific application without requiring the development of custom components. These features work together to provide a superior clamping solution at a lower cost, saving hundreds of dollars per clamp.

The design of Misati clamps allows for a smaller diameter apparatus to generate up to 333% more force than other clamps. Misati clamps are up to 42% narrower than typical clamps, so are ideal for applications in confined spaces. The design of the force mechanism employs a smaller-than-typical stroke that uses less air per cycle.

The next illustration shows how Misati’s clamps achieve more force with a smaller diameter apparatus.

The sturdy design of these clamps make them suitable for aggressive environments such as machining or resistance welding. They utilize a monobloc body of machined and treated steel, which incorporates the stress mechanism and pneumatic cylinder. The built-in connections have no-flow regulators. If the application requires an extra long arm, a pneumatic cushioning option is available for the clamp.

Pneumatic parts in the clamp can be replaced after wear in a simple manner that doesn’t require removing the clamp from position. The mechanism that generates the force of the clamp has been designed with roller bearings for long life. Each clamp is stamped with the month and year of manufacture, and guaranteed for five years or 20 million cycles.

Clamps are also available in an “anti-spatter” version that is resistant to rust, salt, solvents and chemicals. It is thermal resistant and has an antistatic Teflon coating.

The next illustration is a breakdown of the many advantages of this clamp design.

Misati clamps are offered in four styles, with piston lengths from 20 to 50 mm. The design of the clamp permits either front or lateral mounting with centering guide bushings. They also do not use lateral sockets, which makes for simple installation even in small spaces. Positioning can be highly accurate, and clamps can be interchanged easily. Clamps may also be affixed using a collar that permits them to be easily rotated in place.

Here are some examples of different clamp assemblies possible with the many accessories available.

A broad variety of types of gripper fingers allow the clamp to be configured perfectly to application requirements. Gripper fingers that use a ribbed ball-and-socket joint are available and provide a high friction grip on unmatched surfaces.

Jaw blocks reproduce the surface of the piece to be clamped. Shims are offered to regulate the clamping further. A leveling ball-and-socket joint is useful for clamping delicate pieces. Centering guide bushings can be employed to withstand lateral forces and precisely place couplings and mountings. Other accessories include rearside protection plates, built-in sensors, and cable connectors.

Fastening of accessories uses threaded set screws, socket cap screws, and upper or lower centering guide bushings, making it easy to assemble, center, and exchange parts.

Guide rail brackets are just one element of J.W. Winco's newly launched line of conveyor components. To see the full range, visit Section 17 of our online catalog.

GN 350.2 Steel Leveling Sets with Spherical Washers

2009-10-08T09:08:00.003-06:00

Diane here, showcasing another recent addition to our product line: our series GN 350.2 Steel Leveling Sets with Spherical Washers.

These leveling sets are used for leveling, adjusting, and linking operations. Offered in metric sizes, the sets are RoHS compliant. They are made of zinc-plated, blue passivated steel.

The spherical washer allows precise installation of two non-parallel planes at a required gradient up to ~4°. Leveling sets consist of a threaded upper sleeve and a tapped lower sleeve. The fine thread allows precise, stepless setting and locking using a DIN 1810A hook spanner wrench. An anti-rotation disk serves also as a height limiter for the maximum height. Normally this screw is permanently and securely locked by the static load created when the mounting screw is tightened. If this is not sufficient, the use of a locknut is recommended. A version including the locknut is offered.

For more spherical washer options, visit Section 11 of our online catalog.

GN 6333 Metric Size Quick Release Hex Nuts

2009-09-29T10:22:00.005-06:00

It's Diane introducing another new product today...our series GN 6333 Metric Size Quick Release Hex Nuts.

The nuts are RoHS compliant and made of forged, zinc-plated steel with a tensile strength of 1000 N/mm2. They are useful for applications where the nut needs to be moved quickly to the clamping position, and to be removed quickly after loosening. There is no “locking’ of the thread. Quick release hex nuts provide easy mounting/dismantling, even in tight spaces.

For more nuts and other fasteners, see Section 11 of our online catalog. Go nuts!

GN 927 Clamping Levers with Eccentrical Cam

2009-09-16T12:46:00.004-06:00

Diane posting today with another of our new products, our series GN 927 Clamping Levers with Eccentrical Cam.

These clamping levers are used for rapid clamping and releasing, and come in both tapped and stud types. In contrast to a clamping operation utilizing threads, these levers permit torque-free clamping. The lever has been designed to insure that its movement cannot exceed the maximum clamping position, and there are no loose components since all are assembled and mounted in their correct order.

The levers are RoHS compliant, with zinc die cast handles and a matte black plastic coated, abrasion-proof epoxy resin finish. Components are zinc plated, blue passivated steel.

These levers are available with two types of technopolymer contact plates: a fixed version, or an adjustable contact plate, with which the distance between the eccentrical cam and the contact surface is adjustable by means of a fine threaded knurled nut. The second option permits the maximum clamping force to be set by a simple adjustment. With these clamping levers, thrust forces of up to 8 kN can be obtained.

Selecting a Crank

2009-09-10T09:03:00.006-06:00

Diane here, and I’ve sorely neglected an essential category of machine parts, the humble but useful crank. Before these components get cranky (oh, that was bad), let’s talk about how to select the proper crank for your application.

By definition, a crank is a device for transmitting rotary motion, consisting of a handle or arm attached at right angles to a shaft. Simple enough, but there are some variables.

Balanced cranks: This type of crank has a center mounting point, which allows for smooth operation in either horizontal or vertical directions. Its design permits precise adjustment, and in applications with vibration, it will remain stationary. An example is our GN 10 series Steel Tri-Ball Handle.

Cranks: Standard cranks are mounted on one end, giving them one-handed leverage that works well for high torque applications and fast operation. They are well suited for clamping, and can be removable. Shown here is our GN 471 series Aluminum Cranks with Revolving Handle. Other options for materials for cranks are zinc die-cast, steel, stainless steel, cast iron and various plastics (nylon, phenolic, technopolymer).

Fold-Away Handle Cranks: Sometimes the application requires, for design or safety reasons, that the handle be retractable. An example is our GN 471.3 Aluminum Cranks with Retractable Handle. The handle firmly locks into position when folded or when in the operating position. We also offer styles where the handle fits neatly into a recess.

Off-Set Handle Cranks: The design of your machine may require a handle that is off-set, so that it clears obstructions when turned. Shown here is one of our DIN 468 series Off-Set Crank Handles. This cast iron crank is offered with a fixed or revolving handle, and round or square bore.

Racheting Cranks: The combination of a crank and a ratchet arm creates high torque. This mechanism also works well in a confined or limited space. The example I show here is our LR 318 series Steel Ratcheting Crank Handles.

Four-Arm Levers: A variation on the crank is the four-arm lever, which is really four cranks combined in one. This obviously increases its clamping capability. It also makes for good control with either one or two hands. Here you see our series GN 213 Four-Arm Turret Levers.

I wanted to close with a unique crank that was patented by J.W. Winco, our WRHC Nylon Plastic Retractable Hand Cranks with Revolving Handle. This cranks was designed for use in any application requiring the complete crank handle to be folded out of the way. Pretty nifty, huh?

For our entire selection of cranks, visit Section 6 of our online catalog.

GN 113.6 Heavy Duty Self-Locking Release Pins

2009-08-26T13:10:00.003-06:00

Diane here, with another new product to introduce to you: our series GN 113.6 Heavy Duty Self-Locking Release Pins.

These release pins are RoHS compliant, and use a ball lock mechanism for rapid connection and securing of components or work pieces. A typical example would be bearing shafts which have to be regularly mounted and unmounted. By depressing the spring-loaded push button, the two balls are freed, and by releasing the button, they are locked.

The release pins have nylon plastic handles, with shafts, balls and springs of heavy duty, hardened and highly abrasion-resistant stainless steel, giving them a high load capacity. Series GN 111 split rings with chains are also available to prevent misplacement of the release pins.

To see more rapid release pins, including the steel version of this one, visit our Section 10--Indexing, Spring and Ball Plungers.

We Agree with Mythbusters’ Jamie

2009-08-20T08:50:00.003-06:00

Diane here, to confess that I’ve been a fan of the Discovery Channel’s “Mythbusters” for years. Jamie Hyneman, Adam Savage, and the members of the Build Team demonstrate again and again how fascinating science and engineering can be.

I recently read a great piece written by Jamie for Popular Mechanics called "Is Computer Design a Substitute for Hands-on Experience?" Jamie’s contention is that in spite of all the amazing advancements in computer-aided design, CAD is only as good as the engineer using it. He points out the importance of looking at CAD as a tool, no different than a hammer, that augments skill but doesn’t guarantee perfection.

It’s true. Someone like Mike Holmes from "Holmes on Homes" is a lot better with a hammer than I am, and it’s not the hammer’s fault that I can’t get use it to get the same results as Mike. A hammer improperly used only causes damage. The same can be said for computer-aided design.

Now Jamie admits that CAD does better than "junk in, junk out"...what comes out of good CAD software will certainly be workable. However, it may well be impractical, overly complex, or otherwise a poor solution, if the tool hasn’t been utilized properly.

An example Jamie uses to illustrate this point is an experience with the unfortunate placement of a car battery he needed to remove. The car’s designer no doubt used CAD to make sure the battery would fit in the space allowed, but failed to use his own brain to consider the difficulty involved if one wanted to replace said battery. Jamie had to take off the front wheel and inner fender to do this basic piece of maintenance. Someone familiar with car maintenance and its importance (and honestly, who over 16 isn’t?) should not have made such a critical design mistake.

So no matter how sophisticated your design tools, nothing can take the place of understanding the intended purpose of a machine, performance and maintenance issues, and the properties and functions of the materials used. Sometimes the most efficient way to consider all those factors is simply to use the head of an expert, whether that be yourself or another human being.

J.W. Winco has free CAD files on our Web site, in all possible file formats, because we recognize the tools engineers use to do their work. We also provide as much technical information on our components as we can. However, unlike many of our competitors, we also recognize that good engineers depend upon human involvement when trying to do a job right. Our technical sales associates have great expertise, including years of experience advising designers on the best ways to use our parts. And what we don’t know, we know how to find out.

So we’re with Jamie on this one. Tools will only take you so far; the best machine designs depend upon the wisdom and experience of people. Call us at 800-877-8351 or email sales@jwwinco if you’d like our people to help.

GN 237-NI Stainless Steel Hinges with Countersunk Thru Holes

2009-08-13T08:07:00.002-06:00

Diane posting, with another one of the new additions to our product line. This time we're featuring our GN 237-NI series Stainless Steel Hinges with Countersunk Thru Holes.

These hinges are RoHS compliant. Both the hinge body and pin are constructed of stainless steel. A zinc die-cast version with black powder coated textured finish is also available.

New Metric Size Washers in our eStore

2009-08-10T09:56:00.014-06:00

Diane reporting, to let you know that we’ve added more metric fasteners to our Web site for online pricing and purchase. The new offerings are five series of washers.

First up is our metric size BN 791 Ribbed Lock Washers. These are available in steel or stainless steel and are used with hex cap and machine screws. When the screw is tightened, the serrations crunch into the mating faces which prevents the screw from loosening up due to vibrations, etc. These washers are used for high vibration resistance due to positive rib contact; and offer excellent pretensioning. We also offer a zinc-plated steel version, our BN 792 series.

Next up is our metric size DIN 9021B Flat Washers in zinc-plated steel. These washers are also known as fender washers. The sizes less than 16 mm are 140 HV class, 140-250 hardness HV; sizes larger than 16 mm are 100 HV class, 100-250 hardness HV.

Here are our metric size DIN 6798A Serrated Lock Washers. They are made of zinc-plated spring steel and have external serrations.

Lastly, I present our metric size DIN 127B Helical Spring Lock Washers. They are available in spring steel, 450-530 HV hardness, with a plain finish; spring steel, 450-530 HV hardness, with a zinc-plated finish; or A2 stainless steel, with plain finish. These washers are without jaws and have square ends.

The Pros and Cons of Aluminum

2009-08-05T12:54:00.014-06:00

Diane reporting today! You know, the Barenaked Ladies recorded a song called “Aluminum” which begins: “How, in every visible way, you shine / As if the stars in your wake align.”

High praise indeed, and in fact aluminum is an excellent material for machine components, offering many beneficial characteristics.

First let me get the disadvantages of aluminum out of the way, and it is a short list. This metal is more rare and more expensive than steel. It is abrasive to tooling, or more accurately, the aluminum oxide coating that forms upon it is. It is prone to severe spring back. And it requires special processes to be welded.

But those cons aside, aluminum has many useful traits:

● Corrosion-resistant: Aluminum oxidizes quickly, and the resulting surface coat of aluminum oxide resists further corrosion, by air, water, and chemicals. This protective coating is clear, colorless, and non-staining.

● Economical: No, I’m not contradicting myself. Aluminum is still more economical than brass or stainless steel, so is often the best option for non-corrosive applications.

● Lightweight: Aluminum weighs about a third of what steel does. That makes it inexpensive to ship and can also contribute to making a lighter machine when that is desirable.

● Strong: Aluminum has the highest strength-to-weight ratio of any metal.

● Electrically conductive: Aluminum conducts electricity even better than copper.

● Non-magnetic: For applications where magnetism needs to be avoided, aluminum is an excellent choice.

● Colorable: Aluminum can be easily colored by anodization, and holds paint extremely well.

● Recyclable: Aluminum is 100% recyclable without losing any of its natural characteristics.

J.W. Winco’s product line includes many items manufactured of aluminum, a sampling of which you see pictured in this post. Presented here is our ALCK Control Knob, our GN 565.2 Angled Cabinet U-Handle, our GN 322 Two-Spoked Handwheel, and our GN 744 Fluid Level Sight Glass.

These components were fabricated of aluminum to take advantage of its many fine qualities…and you could fairly say of them, in every visible way, they shine!

GN 665 Series Arched Pull Handles

2009-07-29T13:21:00.002-06:00

Diane here with another new product to introduce to you from our line of standard machine components. Today we're showing off our GN 665 Series Arched Pull Handles.

Available in metric sizes, the tapped-type handles are produced from elliptical aluminum extrusions and have a black powder coated textured finish. The end pieces are made of zinc die-cast with a silver powder coated textured finish. The mounting screws, hexagon nuts, and washers are zinc-plated.

These handles are notable for their elegant design and are RoHS compliant.

Characteristics of Common Plastics Used in Machine Components

2009-07-23T08:34:00.007-06:00

Diane posting, here to talk about—or rather scratch the surface of—plastic. In the nearly 150 years since plastic materials were conceived, these man-made materials have evolved into countless types for every possible use. Today I’ll just touch on a few categories of plastic that are frequently used in industrial parts.

Nylon is a technopolymer, and is typically referred to as polyamide (PA). Nylon was the first commercially successful synthetic polymer. The wide variety of different modifications that can be made to technopolymer allows it to be produced with different mechanical properties, chemical resistance, temperature resistance and colors, even crystal-clear. Nylon can be used as the matrix material in composite materials, with reinforcing fibers like glass or carbon fiber, and which then have a higher density than pure nylon. Such thermoplastic composites (25% glass fiber) are frequently used in components where their good heat resistance—up to 150°C (300°F)—making them practical competitors with metals. Glass fiber reinforced nylon is used in the production of J.W. Winco’s WN 300 Nylon Plastic Adjustable Levers, shown here.

Polypropylene (PP) is a thermoplastic polymer that is rugged as well as unusually resistant to many chemical solvents, bases and acids. It is resistant to fatigue and tolerates high heat—66°C (150°F). It can be extruded or molded. Many physical finishing techniques can also be used on polypropylene, such as machining. Surface treatments can be applied to PP parts in order to encourage adhesion of inks and paints. Fiberglass reinforced polypropylene is used for our MFE Cabinet U-Handles.

Elastomers/thermoplastic elastomers are polymers with the property of elasticity. The term, which is derived from elastic polymer, is often used interchangeably with the term rubber. Components of these materials can be stretched and bent without exerting great force. Once the deforming force relaxes or no longer acts at all, the parts take their original shape. At ambient temperatures rubbers are relatively soft and deformable. Their primary uses are for seals, adhesives and molded flexible parts such as wheels. Elastomers can be made in varying degrees of hardness and can be dyed easily. Elastomer is also often used for non-skid pads like those on the bases of our SNSM Snap-Lock Non-Skid Leveling Mounts.

Thermoplastic elastomers (TPE), sometimes referred to as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) which consist of materials with both thermoplastic and elastomeric properties. TPE is used as an outer coating on our EN 5337.6 Softline Star Knobs, to provide a soft, ergonomic grip.

Duroplast is a resin plastic reinforced with fibers (either cotton or wool) making it a fiber-reinforced plastic similar to glass-reinforced plastic. It is light, flexible and strong, but has low elasticity. Phenolic resins are among the most commonly used Duroplast materials. Unlike technopolymer, Duroplast and phenolic plastics cannot be melted because they remain rigid up to degradation temperature. The coloring and dyeing options of components made of Duroplast are limited. Duroplast is used in our EN 940 Three Spoked Handwheels to make them strong and durable.

Like I said, that just scratches the surface of plastics and all there is to know about their use in industrial components. You can find some additional technical information about plastics in our Web site’s Technical Section, including General Heat Resistance for Plastic, Material Characteristics Chart of Duroplast and Technopolymer Plastics, and
Material Properties Chart of Elastomers (Rubber).

GN 316 Interchangeable Insert Ratchet Wrenches

2009-07-15T10:54:00.005-06:00

Diane reporting, with another new product from our line: series GN 316 Interchangeable Insert Ratchet Wrenches with Reversing Lever. Made of steel and available in metric sizes, these RoHS-compliant Ratchet Wrenches are ideal for assembly and repair work, as well as fixed applications on machinery and equipment. The housing of the wrench is coated with black matte plastic in a textured finish. The knob is made of glass fiber-reinforced polyamide technopolymer.

In order to reverse the operation of this wrench, you simply move the cam lever from its middle position either to the left or to the right to obtain the function required. In the middle position the ratchet function is eliminated and the spanner can be used in both directions as an ordinary wrench.

These wrenches are available in tapped insert type, round bore with keyway, and square bore type. The inserts are easily interchangeable--to exchange the inserts remove screw and cover--and can be supplied individually upon request. For certain minimum quantities, hexagon and modified inserts with inch size threads, round bores with keyway, and square holes are available. Other handle lengths are offered upon request.

Choosing Spring Loaded Devices for Positioning and Locking

2009-07-13T12:18:00.024-06:00

Diane here, to talk to you today about the engineer’s options when he/she needs to align, hold, or latch different parts of equipment together. When this is your objective, you need a spring loaded device, and the options for that component are many and varied.

Breaking it down most simply, these sorts of devices consist of a body, an internal spring, and a ball or nose. They may also have a knob, button, or lever for the operator to control by hand. The general purpose of these components is to use the force in the spring to apply pressure so that the ball or nose will remain nested in some sort of hole or other receptacle. This way two or more elements of the equipment can be aligned or fixed into a determined relative position.

There are countless uses for positioning and locking components. They are used in workholding applications, as well as for indexing, latching, ejecting, and even electrical contacts.

So let’s examine the various types of components in this category (featured in our Section 10, Indexing, Spring and Ball Plungers).

Indexing plungers: These have a beveled or rounded nose that inserts easily into an indexing receptacle. The nose is long enough to fix the position firmly, preventing movement in any direction. In order to move the position of the plunger, the operator must mechanically retract the nose. An example is this GN 617 indexing plunger (non-lock out type).

Spring plungers: Spring plungers differ from indexing plungers in that they have a nose designed to allow for movement when some side force is applied. In other words, it isn’t necessary (or possible) to retract the nose mechanically. Consequently, these plungers are not appropriate if heavy side load is involved in the application. Shown is our SPNL short spring plunger (note the nylon locking element in the side of the threaded body).

Hand-retractable spring plungers: These plungers are sort of a hybrid of the two above types, and include a knob for manual retraction of the plunger. Among other things, they are used for manual or automated holding, as in workholding applications. Here you see our LRSS stainless steel hand retractable spring plunger (lock out type).

Ball plungers: These have a ball instead of a nose, and no knob. The shallow depth of the ball allows for easy movement in and out of position, but as with spring plungers, they do not perform well with heavy loads. The illustration is our GN 615 steel ball plunger with threaded body (note the slot provided for installation with a screwdriver).

Side thrust pins: These components are designed for fixturing small parts and holding them in place with constant pressure, as shown in the illustration. In the photo you see the GN 713 zinc-plated steel side thrust pin, which has a threaded body.

Quick release pins: Instead of body with a nose, these components consist of a rod or stem, from which small side securing pins protrude. A button in the handle retracts or extends these pins so that the quick release pin can be removed or secured in place (see application example).

The component in the illustration is our GN 114.2 steel rapid release pin. We offer many other options for quick release pins, including stainless steel components, heavy duty construction, and self-locking features.

So far this seems fairly simple, right? Spring-loaded components aren’t rocket science (especially if yours truly can explain them). We offer these types of components in many sizes, both inch and metric. But there are more options than that to consider. Let’s start with balls and noses.

Balls and noses: Balls, as mentioned above, allow for easy position changes. However, their holding force is limited. Noses may be round for reduced friction and similar easy positioning. They can also be chamfered for easier insertion into indexing holes. Flat noses have a larger contact area but will obviously resist side motion. Hex noses can allow installation of the plunger from the front with a hex wrench, but are subject to faster wear.

The material chosen for the ball or nose is also key: case hardened steel noses are strong and heat-resistant, but can mar the surface to which they press. Delrin® is a very strong plastic that holds up well, is self-lubricating, and will not mar. Nylon also resists marring and corrosion but doesn’t wear as well and can’t be used in temperatures above 82ºC (180ºF). Phenolic plastic is an economical option but is more brittle. Stainless steel is the best choice for sterile applications.

Body attributes: The body of a plunger varies depending upon installation considerations. It may be threaded, it may have a lock nut for securing the mounting (see illustration). Or it might be smooth for push-fit installation, or smooth and weldable. Threaded body plungers may have a locking element or patch. There may be a hex or slot on the end to assist in mounting.

The same material issues apply to the body as to the nose or ball. Case-hardened steel stands up to high forces. Steel may be zinc-plated or have a black oxide finish. Stainless steel tolerates high forces, heat, and corrosion. Brass is another option for metal plungers. As for plastic, a Delrin® body is non-magnetic and resists corrosion but will not tolerate heat.

Space considerations may require you use a short or stubby plunger. An extra-long plunger (“long-travel”) or long nose can be used to meet side force holding requirements or for holding up metal sheets. This latter is illustrated by our GN 611 long stroke spring plungers.

Springs: Springs are generally made of steel or stainless steel, and their end force determines the applications for which the plunger is appropriate. For detents, you will need a heavy or standard end force. If you want an easily retractable plunger, use standard or light end force. Heavy end forces permit the plunger to hold its position by end force alone. Light end forces prevent marring. Many of our plungers are available in all three versions.

Hand-operating elements: For hand-retractable plungers, the plunger incorporates an element that the hand can hold, pull, or manipulate. Options include knobs with or without knurling, L-handles, T-handles, and pull rings. Some plungers have a threaded end that will accept whatever knob or handle the user wishes to install. There is also the cam-action indexing plunger, which is designed so the turning of a handle in a circular direction causes the nose to retract.

J.W. Winco offers the unique type of cam-action indexing plunger pictured here, which permits the plunger pin to be held in either a retracted or protruding position. View GN 712 and GN 712.1 for full details.

Lock out or non-lock out: Last, but not least, is the issue of whether or not the plunger needs the option of holding a retracted position. Lock out type plungers are designed so the operator can pull the plunger into a retracted position, perform a turn of the knob or handle, and let go, and the plunger nose will stay retracted. Cam-action plungers may be either version.

Receptacles for plungers: Obviously the ball, nose, or pin of a plunger or release pin needs a receptacle. The receiving element need be no more complicated than a drilled hole or indentation. It may also be a flange or a mounting block that is mounted by welding or screws to a surface. See the illustration for an example using a mounting block, our GN 412.2.

Accessories: Spacer bushings are a useful component of plunger applications, and compensate for the body thread lengths on indexing plungers to allow mounting through walls of varying thicknesses. Ball chains and lanyards can be used as ways to “tie” removable plungers and release pins to a piece of equipment so they will not be lost, as you see in the illustration (our GN 113.3 rapid release pins with a ball chain).

Well, as far as these varied and useful positioning and locking components, that’s all I got. But if you want to know even more, visit Section 10 of our online catalog, or contact one of our Technical Sales associates!

GN 417 Indexing Plunger Mechanisms

2009-06-29T09:37:00.005-06:00

Diane here, with another new product recently added to our line: series GN 417 Indexing Plunger Mechanisms.

These mechanisms offer a possible mounting option for applications requiring a latch, and are RoHS compliant. The plunger housing is zinc die-cast with black plastic coated textured finish. The plungers themselves have stainless steel plunger pins and springs, with the option of a pull ring in stainless steel, or a pull knob of matte black glass fiber reinforced nylon plastic. The fastening range of these mechanisms is designed to accommodate ISO 7092 washers.

The Right Component for Your Applied Force

2009-06-23T13:03:00.008-06:00

Diane posting today, and thinking about the process of selecting the right component based on what it needs to do. What I mean is, starting with the motion or action required of the operator, considering the requirements of the application and the environment in which it will be used. Is a knob appropriate, or would a U-handle be better? What sort of U-handle?

So let’s do a handy little rundown of the “applied forces” that an application may require, and review the best types of components for each motion.

1. Lift. You can use a knob for lifting if the force required is less than a pound, but typically U-handles are the best choice. Directly fighting the force of gravity generally requires a more heavy-duty handle, like a bridge handle (see here our EN 628.1 bridge handle), and you’ll definitely need to know the load capacity, to be sure it can hold up to the strain. Our catalog at www.jwwinco.com includes load capacity for our U-handles.

2. Up-Down. This refers to the direction of motion applied, and differs from lift in that you are not lifting the entire weight of the apparatus. Because the force is significantly less, you could use a ball knob, push-pull knob, a U-handle, or a handle.

3. Left-Right. Obviously, 90 degrees off from #2 above, you can use similar components.

4. Pull. Again, ball knobs, push-pull knobs, and U-handles all work. But when choosing the right one, take into account how much force will be used (for more force, use a U-handle), and consider the ergonomics involved (for two-finger pulling, use a knob that allows for grip, is comfortable, and is non-slip, like our GN 76 mushroom knobs).

5. Push. Use a ball knob or push-pull knob. If the application requires a larger knob, make sure it fits comfortably in the palm. If using a smaller knob, you may want to choose one with a concave surface to prevent the finger from slipping.

6. Push-pull. When both motions are significant, you may be looking at an application that requires more force, and therefore a larger component. Make sure the knob or U-handle is comfortable to operate and allows for a good grip.

7. Circular. To determine the best component for a circular motion, you must consider many aspects of the application. If you’re looking for fine, precise adjustments, a control knob is best. If you want a larger range of motion or are moving more mass, choose a crank handle or a handwheel. (Handwheels with digital indicators to measure the motion are an option, like the HK/HKL series.) A control lever is another possible choice.

8. Circular for clamping. If the circular motion is being used to clamp or release, an adjustable (clamping) lever could be your best choice. We offer the unique torque-free component shown here, the GN 927 clamping lever with eccentrical cam. If you want to use a knob instead, a lobe or prong knob would be your best bet, as these allow for the grip required for turning. Handwheels are another option.

9. Rotate. Your options for rotating motion are many, and depend upon the torque and speed needed, as well as the space accommodations. In confined spaces, use a lever with a ratcheting feature or an adjustable lever. For low torque, use a knurled, lobe, T-handle, or prong knob. For higher torque, use a crank handle or handwheel. The latter is the best choice if speed is crucial.

10. Rotate-pull. The ideal choice for this is an adjustable lever, like our GN 300.4 zinc die-cast adjustable levers with secure clamping force.

11. Rotate-push. Any knob that provides a good rotational grip will work, such as a fluted, knurled, lobed or prong knob.

12. Multiple motions. A ball knob could work (knurling may be a boon), although a handle would offer more leverage. Choose fixed or rotating based on whether rotation will be required.

Keep in mind that many other factors come into play to determine the size, material, and design of your component choice. But basing your selection on the required applied force and motion is an essential way to begin!

GN 728.5 Economic Stainless Steel Cabinet U-Handles

2009-06-16T07:18:00.005-06:00

It's Diane, presenting another recently-introduced product in our line: series GN 728.5 Economical Stainless Steel U-Handles. These U-handles are cast from European Standard 1.4308 stainless steel with a matte shot-blasted finish, and are RoHS compliant.

We offer these handles in two versions, bottom mount with blind tapped holes, and top mount with thru holes for socket head cap screws. Because the hole center dimension is identical in both versions, they can be mounted in pairs opposite each other. The handles are an excellent low-cost option for applications requiring stainless steel.

Sanitary Machine Design

2009-06-05T07:41:00.009-06:00

Diane here, focusing on the topic of how to design machinery for clean room applications. If a machine is to be used for food processing, medical use, or other sanitary applications, there are a lot of things to consider in the design. And of course, that means making sure the components utilized are appropriate for sanitary use as well.

The American Meat Institute has prepared an excellent checklist of things to consider when designing equipment of this nature.

1. Cleanable to a microbiological level: Food equipment must be constructed to ensure effective and efficient cleaning over the life of the equipment. The equipment should be designed as to prevent bacterial ingress, survival, growth and reproduction on both product and non-product contact surfaces of the equipment.

Our GN 5339.5 stainless steel triangular knobs were specially designed for use on machinery in the food industry. The smooth and enclosed areas as well as the corner radii comply with the requirements of hygiene standards.

2. Made of compatible materials: Construction materials used for equipment must be completely compatible with the product, environment, cleaning and sanitizing chemicals and the methods of cleaning and sanitation.

Our LWKX-TPA casters are corrosion-resistant and can withstand up to 110°C (230°F) sterilization by pressure steam cleaning, so they are perfect for medical, dental, instrumentation, hospital, food service and laboratory equipment.

3. Accessible for inspection, maintenance, cleaning and sanitation: All parts of the equipment shall be readily accessible for inspection, maintenance, cleaning and sanitation without the use of tools.

4. No product or liquid collection: Equipment should be self-draining to assure that liquid, which can harbor and promote the growth of bacteria, does not accumulate, pool or condense on the equipment.

The design of our GN 565.5 stainless steel handle is without hollows or other places that debris might collect.

Of similar material and design is our GN 949 stainless steel handwheel, also appropriate for sanitary applications.

5. Hollow areas should be hermetically sealed: Hollow areas of equipment such as frames and rollers must be eliminated wherever possible or permanently sealed. Bolts, studs, mounting plates, brackets, junction boxes, nameplates, end caps, sleeves and other such items must be continuously welded to the surface not attached via drilled and tapped holes.

Our GN 341.1 leveling feet are designed with a convex bolt head seat on the base to reduce the formation of deposits and simplify cleaning. The adjustable height sleeve shrouds the thread to resist accumulation of impurities.

6. No niches: Equipment parts should be free of niches such as pits, cracks, corrosion, recesses, open seams, gaps, lap seams, protruding ledges, inside threads, bolt rivets and dead ends.

7. Sanitary operational performance: During normal operations, the equipment must perform so it does not contribute to unsanitary conditions or the harborage and growth of bacteria.

Obviously one way to achieve this is the use of stainless steel components. Yet another example of our many all-stainless steel parts is the GN 300.5 adjustable lever.

8. Hygienic design of maintenance enclosures: Maintenance enclosures and human machine interfaces such as push buttons, valve handles, switches and touchscreens, must be designed, to ensure food product, water or product liquid does not penetrate or accumulate in and on the enclosure or interface. Also, physical design of the enclosures should be sloped or pitched to avoid use as storage area.

9. Hygienic compatibility with other plant systems: Equipment design must ensure hygienic compatibility with other equipment and systems, such as electrical, hydraulics, steam, air and water.

10. Validated cleaning and sanitizing protocols: Procedures for cleaning and sanitation must be clearly written, designed and proven effective and efficient. Chemicals recommended for cleaning and sanitation must be compatible with the equipment and the manufacturing environment.

“Keeping it clean” can be painstaking when you’re designing equipment. We’re here, as always, to advise and assist with your cleanroom machinery project.

The Circle of Commerce: Parts for Printing Equipment

2009-06-02T10:36:00.005-06:00

Diane posting, after a recent visit to the plant that has printed our company’s catalogs for many years. Ripon Printers is a large facility in central Wisconsin that has a full range of coldset and heatset web presses as well as sheetfed equipment. They also have high capacity, specialized bindery equipment, and offer folding, drilling, shrink-wrapping and polybagging services as well.

Needless to say, Ripon has an impressive plant, with lots and lots of machines. As we bided our time between press checks of our new 1,000-page catalog, we looked at some of them. There was a stacking machine nearby, as you see here.

And all over this machine, we spotted J.W. Winco parts! Indeed, the manufacturer of this machine happens to be a customer of ours. It’s not surprising—the printing industry is a major user of the kinds of components we supply.

Certain workings of this stacker are controlled by these GN 324 type handwheels with revolving handles.

Other parts we spotted included our very popular GN 300 adjustable levers and FPKS four-pronged knobs.

It was an excellent example of what I call “the Circle of Commerce.” We are a customer of Ripon Printers, they are a customer of the stacker manufacturer, and the stacker manufacturer is a customer of ours!

Indeed, the world’s commerce is like one big well-oiled machine, and it’s exciting to be a part of it.

GN 711 Metric Size Self-Adhesive Rulers

2009-05-18T07:38:00.005-06:00

Diane here, with another one of our featured products. Today we look at our series GN 711 metric size self-adhesive rulers. These are handy for use in coordination with control knobs when you want to add a means of measurement to your machine, and are one of the items offered in our Section 9, Control Knobs.

Three models of this self-adhesive ruler are available and all are RoHS compliant. The stainless steel version is scale etched and 0.6 mm thick. A white plastic version is highlighted in silver, scale printed, and 0.3 mm thick. The transparent plastic version is scale printed and 0.3 mm thick. Six different figure sequences are available, and the rulers are offered in 100, 200 and 300 mm lengths.

To apply the ruler, the protective strip is removed from the back and the ruler can then be affixed to the specific surface. Meanwhile, we also offer GN 711.1 indicator arrows in all three materials for use with these rulers.

Put a Toggle Clamp on the Barbie

2009-05-14T07:56:00.004-06:00

Diane reporting today, and I'm in a summer mood. That's because this past week a clever do-it-yourselfer who calls himself “Arctikdog” posted to the Weld Talk message board all about his latest project. He built himself two double walled and insulated cabinet smokers, just in time for barbeque season.

I was interested to read his post, not because I can weld, or even because I like brisket. No, I was interested in his use of some of J.W. Winco’s components: our series 431 toggle clamps. I can see why these clamps were an elegant solution to Arctikdog’s design challenge.

As he writes, "The door closure system that I used was a pull down clamp. This gives me a positive closure on the door, and also allows adjustment if your gasket ever gets compressed over time. They were easy to position and weld for me, and I didn’t have to 'invent' something. I got them from J.W. Winco, and they have a large selection of goodies to choose from."

I can see why Arctikdog chose these latch-type horizontal mounting base toggle clamps for his application...I'm sure they serve the purpose perfectly. (By the way, these clamps made of zinc plated sheet metal steel with a red vinyl hand grip, come in three sizes, and are also available in stainless steel.)

Sure, we like it when we can sell a component to an engineer whose project involves a mass-produced machine. But it's also nice when one of our parts just helps a guy have a tastier summer.

Bolt Tensile Strength

2009-05-08T10:57:00.003-06:00

Diane here, posing the question: What’s the difference between my world (the world of the marketing person) and the engineer’s world? Answer: I only deal with three fasteners: staples, clips and tape. Engineers deal with a staggering number of fasteners when creating a design, and even after they’ve selected the appropriate fastener—say, a bolt—there are still numerous things to consider. Today we’ll look at just one: tensile strength.

In my very simplified world of fasteners, my options might boil down to this: which kind of clip will have the strength to hold this number of pages together? The regular staple? The ginormous binder clip? Well, that’s not really an accurate analogy to tensile strength, but the point is, an engineer must be much more particular than I, math- and physics-wise, to confirm the bolt of choice can handle the stress of the job.

Stress of this kind is typically measured in psi (pounds per square inch) or MPa (meter-pascals). Those are measures of pressure, so what you’re looking to find out is the amount a pressure your bolt can handle. This is not a simple question, even if you know the strength of the material used for the bolt. Other factors involved are size of the bolt, whether it’s square or round, whether the threads are fine or coarse pitch (fine threads, logically, are stronger), and much more.

Because of these complexities, bolts are given ratings to simplify your choices. SAE or DIN/ISO grades will provide you with an accurate measurement of the stress a particular bolt can handle. Our Web site’s Technical Section includes a handy chart of bolt minimum tensile strength.

But what exactly is meant by tensile strength? A lot of things, and you can break it down more specifically. First, you have Proof Strength, which is used to determine tolerable torque, and is ~95% of Yield Strength. Yield Strength is the point at which your bolt will start to deform. And lastly there is Ultimate Tensile Strength, the point at which your bolt will break.

There are other factors that influence the stress a bolt can handle in a particular application. For one thing, tensile strength ratings assume the nut is fully threaded onto the bolt. Meanwhile, the nut itself needs to be adequate strength and support the shear load. The machine is assumed to be operating under typical room temperature, and the torque on the bolt needs to be greater than the load torque so that tension changes don’t result in fatigue. There may be other factors besides load that effect the bolt. In an application that is subject to vibration, that means additional stress as the load on the bolt repeatedly reverses.

When I think about all this, I have one of those rare moments when I’m glad I’m not an engineer. I can pretty much eyeball whether I need a paperclip or a ginormous binder clip. If you become as baffled as I am about selecting the right bolt, just call our Technical Sales Associates for assistance. Bolts are included in our Section 19, Fasteners and Seals.

The Wonders of Bearings

2009-05-05T08:52:00.003-06:00

Diane posting, and I just want to share my great admiration for those splendid components known as bearings. Bearings can trace their origins back to the royal halls of ancient Egypt, you know. The logs that were used to roll immense stone blocks for the pyramids were some of the earliest bearings.

I admire bearings because they can be used to outsmart the laws of physics. Well, actually, nothing can outsmart the laws of physics, but smart engineers use some laws to outsmart others. In the case of bearings, we are battling against both friction and gravity, for the purpose of increasing machinery speed and efficiency.

When designing a bearing, the engineer must be at his best. If you’re creating, say, a U-handle, you can err a bit in size and configuration and still have the part perform its function. Not so with bearings: they require precision, or they will do more harm than good to a machine.

You’ll find these durable, high precision components in applications such as computers, VCRs, cars, trains, planes, construction equipment, machine tools, refrigerators and fans.. .wherever there is a requirement for high speed rotation, minimal vibration and noise reduction.

Plain bearings were developed for the automobile industry in the 1920s. Since then, all manner of these useful components have been developed. For example, rod end bearings such as our DIN 648 have an integrated rod that can be used to mount the outer bearing ring. Shown here is the female tapped version; there is also a male version with threaded stem. Various combinations of bearing types can be combined in one housing to manage bearing loads from several directions at once.

For simplicity’s sake, let’s look at how a plain bearing works. Check out our GLRSW Stainless Steel Series K Spherical Plain Bearings for a good example. You have an inner ring and an outer ring, between which may be sandwiched a set of balls, pins or rollers, which are lubricated (the GLRSW uses chrome plated steel ball bearings). One of the rings is fixed, and the other is free to rotate. Some sort of clamping or pressure fit will be used to affix the stationery ring.

The material used for a bearing is key. For its inner ring, our GLRSW uses a special high-strength bronze (CuSn8) with a PTFE liner.

Proper and stable mounting of the bearing are also essential to good performance. Looseness will result in vibration and noise, shock loads relative to speed, and eventually the actual destruction of the bearing and adjacent parts. Meanwhile, seeing as friction always creates heat, wear and tear, lubrication is an essential part of a bearing. Otherwise, once again bearing destruction is the result. The bearings shown on this post have nifty PTFE liners which make them, in fact, self-lubricating and maintenance-free.

You’ll need to bring your engineering expertise “to bear” when calculating the appropriate bearing for your application, taking into account things like static and dynamic load ratings and limiting speed. Fortunately the bearings we offer have all this information included in the dimensional tables, and you can always consult with our Technical Sales Associates for any information you need about our components.

For our selection of bearings, and various components and accessories that work with them, visit our catalog Section 13.

Conveyors: Industrial Slot Car Sets

2009-04-30T08:28:00.004-06:00

It’s Diane again, here to reveal even more about my childhood cravings to be an engineer. The other day I blogged about tube clamping components, comparing them to Tinker Toys. Well, it’s one kind of fun to make structures, and another to make things that move. Even more than Tinker Toys, as I kid I liked toy trains and slot car tracks. What fun to lay out tracks and crossroads and drive little vehicles all over the rec room!

In the industrial design world, the equivalent of this childhood fun is conveyors. The industries that utilize conveyors are in every field you can imagine, but the theme is always the same: moving large quantities of items along a designated path.

The most common type of conveyor is the belt conveyor, which consists of a long belt mounted on a moving chain. The chain conveyor is a simpler version where the product being moved is affixed directly to the chain. A third method of conveying material involves trolleys and slats.

Sometimes conveyors use other sorts of apparatus to move material: a screw for dry bulk substances like grain...a vertical lift conveyor that behaves like a small elevator...roller and skate wheel conveyors for sliding crates along.

Along with the simple belts or chains, there are all the elements of the conveyor support structure: the adjusting rods, guide rails, clamps, brackets and support bases. Like the tube clamping components we discussed previously on this blog, these parts are industrial “Tinker Toys” which work together to make the track that contains and transports materials.

But wait, there’s more: you may also need sensing devices to add intelligence to your conveyor system. These include photocells, temperature sensors, pressure gauges and counters, all of which may serve to sense problems or trigger events.

The possibilities for designing conveyors are as endless as the industries that require them. However, if you know anything about conveyors, there is one common issue: wear and tear. Obviously these installations undergo constant use—sometimes 24/7—and they may be used to transport materials that are abrasive, wet, hot, or otherwise inherently destructive. That’s why any business that operates conveyors must have a source of replacement conveyor components. Kind of like having a hobby store where you can get new HO track, knowing your dog will occasionally chew on your train set.

And it’s also why the initial design of a conveyor system must be mindful of the wear-and-tear issue, both in terms of structure and in employment of components that have good enough quality to stand up to the demand.

The items you see in this post are some of the high quality conveyor components included in our product line. You can check out our catalog Section 17 to see our adjusting rods, cross blocks, clamps, brackets, support heads, and bases. We have access to far more products than these, including all the elements of standard conveyor systems, and our Technical Sales Associates would be happy to assist you in finding everything you need for your conveyor design.

When I was a kid, I used my train set, installed under the Christmas tree, to transport pine needles from place to place. The wear and tear of the pine needles was less of an issue than the disruption when track was displaced by our cat. Maintenance had to be constantly on site making repairs, but that can happen with conveyors.

Choosing the Right Hinge

2009-04-28T12:43:00.013-06:00

Greetings, it's Diane, and I have an interesting factoid for you. Know what is the closest to a rhyme for the word "orange"? Door hinge. Yup, it's a fact.

That's all very well, but seeing as this is the J.W. Winco blog, of course we're going to take our topic a step further and actually tell you about door hinges. When you're building any sort of enclosure with access to it's interior, hinges will be a concern. So here are the factors to consider when choosing the right hinge:

Number one is the weight of the lid or door, which can determine both the size and material of the hinge. Our selection of hinges includes a variety of sizes of hinges in zinc die cast, steel, stainless steel, and plastic, and all of these options have their place.

A less obvious consideration is how the enclosure functions and how the door opens. Will it need to open fully, or just 90 degrees? Which way will it swing? Is there room for external hinges or must they be internal? Will the doors need to hold a particular position? Some examples of hinges with interesting functions from our line include the EN 160 Lift-Off Hinge, which is designed for easy unhinging of the door, and the EN 151.2 Lockable Hinge, with a built-in adjustable lever for locking the door into position.

Meanwhile, our GN 161 Hinges are designed specifically to join standard aluminum profiles, a unique but definitely desirable functionality.

Hinges seem like a very elementary sort of component, but certain design innovations can make them pretty tricky and impressive. Our GN 127 Adjustable Alignment Hinges are available in three versions that make them adjustable in different directions. Their design provides for perfect alignment of a door in its frame.

Meanwhile, if security is an issue in your application, you may want to choose a hinge that mounts on the inside of the door, and/or is welded on, like our GN 128 Weldable Hinges.

And of course, the final element in hinge selection is esthetics. All other functions aside, sometimes you just want a hinge to look good. We offer a hinge that incorporates both form and function, the GN 238 Adjustable Alignment Hinge. It combines the adjustable feature of the GN 128 with cover caps that keep the hinge literally clean while also giving it a clean look.

So that's a quick overview of some of the options when you select a hinge. You'll note that we don't happen to offer a orange door hinge. You know, like in the poem:

An engineer, quite fond of orange,
Was trying to spec in a door hinge...

Yeah, you're right--that's not a real poem. Not much of a rhyme either, if you ask me!

EN 5337.8 Safety Star Knobs with Keys

2009-04-23T07:28:00.004-06:00

Diane here today, with our latest featured product, our new series EN 5337.8 Safety Star Knobs with Keys in metric sizes.

These RoHS-compliant star knobs were developed for applications where access by unauthorized personnel is not permitted. The shape of the keyhole profile is identical to the key profile, and the protruding part of the key can be folded so that releasing and clamping for the knob are not impeded, even when the key is in the lock.

Made of glass-fiber reinforced technopolymer plastic, the knobs have a tapped brass insert and are temperature resistant up to 100°C (215°F). The hand knob has a black, matte finish, and the underside plastic cover is ultrasonically welded to the handle body. The knobs are resistant to solvents, oils, grease, and other chemical agents. The keys are made of red plastic with a stainless steel stem. Several sizes are offered standard, and one with a stainless steel insert is available upon request.

RoHS for Earth Week

2009-04-21T07:29:00.003-06:00

Tomorrow is the big day, Earth Day, and we would be remiss in not celebrating the occasion in our own little way. It’s Diane here, greening it up this week with the rest of the J.W. Winco crew. And our timely topic this week is RoHS.

Maybe RoHS means no more than Roy Orbison High School to you, but to us, it’s something we deal with every day. That’s because engineers often need to know if the components they are considering spec’ing into their designs meet the requirements of the company that will sell the machine. And a lot of times, some of those requirements are environmental, and may involve RoHS.

The Restriction of Hazardous Substances Directive, or RoHS, was adopted in 2003 by the European Union, and took effect on July 1, 2006. While it is sometimes called “The Lead-Free Directive,” RoHS actually restricts the use of six hazardous materials in the manufacture of various types of electronic and electrical equipment: lead, mercury, cadmium, Hexavalent chromium (Cr6+), Polybrominated biphenyls (PBB), and Polybrominated diphenyl ether (PBDE).

The restrictions of RoHS apply to the following categories of equipment:

Large and small household appliances
IT equipment
Telecommunications equipment
Consumer equipment
Lighting equipment—including light bulbs
Electronic and electrical tools
Toys, leisure, and sports equipment
Medical devices (currently under moratorium and exempt)
Monitoring and control instruments (currently under moratorium and exempt)
Automatic dispensers

While RoHS applies to countries in the European Union, other countries have adopted similar regulations, or are currently debating whether they should. Meanwhile, specific manufacturers may require RoHS compliance or other specific requirements concerning the use of hazardous materials.

When we launched our latest version of our Web site last year, we made a point of saving engineers some trouble by addressing RoHS compliance for each of our 1,200 series of included products. Compliant or sometimes-compliant items have an appropriate logo on the page.

For other materials requirements, our Technical Sales Associates are proficient at finding out whatever engineers need to know about the components we offer.

The whole business can be quite complicated. I mean, “Polybrominated diphenyl ether”? That’s a mouthful! But it’s all for a worthy cause: cutting down on toxic materials in order to make the world a healthier place for industrial workers, as well as all of us.

Have a happy Earth Day!

Tube Clamping Components vs. Tinker Toys

2009-04-17T15:01:00.003-06:00

Diane here, digging in our industrial toy box of parts for machine designers, and coming up with a handful of tube clamp components. Ooh, what can we build with these?

Just like with Tinker Toys, the possibilities are endless. You see, tube clamping components are nifty devices that enable you to easily build jigs, fixtures, and operating systems using standard metric round and square tubing.

You have your two-way connector clamps, which connect pairs of tubes at right angles. And there’s your flanged two-way connector clamps, which connect those pairing of tubes to other surfaces. Then there’s your flanged connector clamps, which join a single tube to another surface. You can also connect two tubes in a T-formation, or end to end, or to a swiveling connector, and so on, and so on.

Our line of tube clamping components gives you other options, like connecting a large diameter tube to a small one, round to square, and all those permutations. As I recall, with Tinker Toys the holes were either small enough to hold the sticks tightly, or big enough so they could spin freely. It’s not like they’d work for a square stick!

Meanwhile, there’s the material issues. Unlike Tinker Toys, where your material choice was wood, wood, or wood, these tube clamps come in shot-blasted aluminum, plastic coated aluminum, or stainless steel. Fun!

I know you’re already envisioning the great race car, steam shovel, or windmill you could build with these, but wait, there’s more. Depending upon the requirements of your application, you can control the clamping function on these clamps with a socket head cap screw, a hex head cap screw, or an adjustable lever.

Okay, now for the final awesome element. (And Tinker Toys can’t touch this.) You can incorporate linear actuators in your design. A linear actuator is a guide tube that mounts to other surfaces or tubing and has an internal system that allows you to use a handwheel to move the tube in a linear direction.

Check out this illustration to see how some of these components work. Here you see two linear actuators, each with a handwheel (one has a nifty counter) mounted to each other by a connector with an adjustable lever. The entire contraption has a flanged base.

Way better than Tinker Toys--I know, right? All you need is tubing and tube end plugs (oh, and we have those too) and you have endless possibilities. And seriously, I’m not really talking about race cars, steam shovels and windmills…well, maybe windmills, come to think of it.

So check out our Section 16--Tube Clamping Components, where you can purchase the most popular of these components right online via our estore. We also just added a digital 83 page catalog you can view right on the website to see every possible permutation of tube clamp components and linear actuators we have to offer you, and believe me, it’s cool.

Well, that was fun! Of course, now I’ve got these parts strewn all over the J.W. Winco rumpus room and I have to put them all back in the industrial toy box....but it was worth it to share them with you!

O-Rings for Online Purchase

2009-04-14T07:29:00.004-06:00

It's Diane posting today. As you'd expect, at J.W. Winco we're always working on making our online catalog more complete. It currently contains almost all the components we stock (plus many others we sell), but in the past we have only shown a general sense of the hundreds of metric seals and fasteners we offer.

We hope in the months to come to add many more products in this category, in full detail. That means you'll be able to check pricing for seals and fasteners right online, and purchase them through our estore.

First in line is our OR 638 series of NB70 O-rings, and we want to give these simple but important components a big welcome to the site! We've got about 125 of the most popular sizes of these O-rings available for online purchase, and yes, they are in stock.

Meanwhile, you can still reference our immense online O-ring chart that shows you hundreds of available sizes of metric O-rings. Contact us and we can obtain any of these for you as well. This is a pretty handy chart, by the way, and includes British and Japanese cross references and dimensions for a plethora of O-rings.

You gotta love it when you can use "plethora" and "O-rings" in the same sentence.

We'll be letting you know of more products in this category (our Section 19 – Fasteners and Seals) as they go online.

Joe Grand and DIY Engineering

2009-04-09T13:58:00.006-06:00

Diane here, to talk to you about a guy named Joe Grand. I feel like I am the last person in America to learn about him, so I'm making up for that by offering him the stupendous honor of joining the J.W. Winco Blog's growing pantheon of Engineers We Love.

I learned about Joe from a little piece in the latest issue of Product Design and Development. His subject was how engineering innovation nowadays occurs not only from within the corporate industrial community, but more and more often from hackers and do-it-yourselfers.

And Joe himself is a prime example. As a young guy, he and a group of other hackers who dubbed themselves "the L0pht" made big news by (1) being called upon to testify to Congress about government computer security issues, and (2) claiming they could bring down the Internet in a half hour if they so chose.

Since then, Joe (also known by his handle, "Kingpin" or "KP") has been a renowned inventor, entrepreneur, and author. He also appears on the Discovery Channel's "Prototype This" show, developing inventions like the wearable air bag.

Back to the PD&D story. Joe made the point that the economic downturn has set a lot of engineers loose on the world with mad skills and plenty of free time. As do-it-yourself hobbyists, these folks are congregating on sites like Hack-a-Day, MAKE, and Joe’s own Grand Idea Studio, comparing notes, sharing information.

And what are these DIY engineers up to? Well, they're tweaking existing consumer products into new versions. And they're also devising completely new stuff, like stationary bike book holders and robots with 3D heads modeled of your face. You could spend all day checking out these great inventions! (No, Boss, I didn't spend all day doing that...I wrote this post, for one thing!)

At J.W. Winco we have a history of supporting DIY-ers by supplying them with standard components that, while simpler than a servo, can be essential parts to home engineering projects. For example, over the years we have sold lots of our DIN 6335-TP star knobs to folks who have downloaded this great plan for making your own drafting table, designed by a customer of ours named John Petersen.

Our Technical Sales Associates work with engineers from huge corporations, but they are just as happy to assist hobbyists and do-it-yourselfers. And we'd love to help you out sometime, Joe Grand! I can picture our adjustable levers incorporated into something like your Gamecaster Cybercam, for sure!

What Type of Leveling Device Should I Use?

2009-04-08T07:36:00.029-06:00

Diane here, trying to resist the temptation to pun on today’s subject. You know, stuff like "in today's post I'm going to level with you." That's because today's post is all about levelers, aka leveling pads or feet or mounts. These simple devices support your machine, and therefore, are as varied in design as machines themselves.

Will the equipment be motionless or will it involve vibration that needs to be controlled? How much weight must the feet support? What type of floor will the machine stand on, and will the environment be wet, hot, caustic, sterile? Let's talk about some of these considerations and how they affect your choice for best leveling device. I promise not to "pad" this post with non-essential info. I will put my best "foot" forward. Ooh, the suspense "mounts." Sorry. Let's begin.

First, the two basic styles are:

Tapped type: These are mounts that have a tapped hole for attaching to a threaded fastener, i.e, the "female" style. Your advantage is a lower profile, but what you lose is the ability to adjust the height, as you would with a stud type. Pictured here for illustration is a tapped version of the Ny-Lev mounts we manufacture right at J.W. Winco.

Stud type: These types of leveling feet have a threaded stud for both attachment and leveling. The stud is easy to attach, and the position can be locked using a jam nut, typically included. Standard stud lengths are available, and you also have the option of cutting the stud to length. Shown here is the stud version of our Ny-Levs. We offer tapped and stud Ny-Levs in inch and metric sizes, in many base sizes, stud lengths, and different threads.

Second, choose your materials. In the interest of strength, in most cases the socket (tapped type) or stud is made of metal. However, the base material varies:

Plastic base: Pros are the lighter weight and reduced cost. Also can add vibration control. Cons are reduced load tolerance and durability. Shown is the GN 343.3, a technopolymer plastic base alternative to our Ny-Levs.

Metal base: Supports heavier loads and provides greater durability. Downside is you are adding more weight than with a plastic base. Also, you'll have poor vibration control unless you also add an elastomer pad. Here you see the GN 340 steel base leveling mount, offered with or without a pad like so many of our levelers.

Stainless steel: For food industry, medical, and other sterile applications, you may need a stainless steel base or all-stainless steel leveling mount. Many of our levelers are offered in stainless steel versions. We also have a special mount for sanitary applications, the GN 341.4 that you see pictured here.

Now consider some special features:

Non-skid: If slipping and sliding of the machine is a concern, you may want to add a non-skid pad to your leveling foot. Many of the mounts in our offering include this option. We also offer the Snap-Lock mount, pictured here, which is designed with a special snap-on non-skid pad that resists peeling off.

Swivel-ability: Whether tapped or stud type, these types of levelers include a bearing surface or other means for the base to swivel up to 15° off axis on uneven surfaces. This allows the leveling mount to adjust to uneven surfaces for maximum surface contact and greatest possible stability of equipment. Many of our levelers offer the swivel feature, like the Level-It mount, shown here.

Anti-vibe/heavy duty: Of course your choice of leveler will be determined in part by the weight of the machine it must support. Our leveling mounts dimensional tables also include load information. A corollary issue to load is the amount of vibration the machinery generates. If vibration is a concern, look for mounts designed to be "anti-vibration," like our Anti-Vibe line, sample pictured here.

Got an extreme situation like drill presses, CNC equipment, stamping presses or injection molding equipment? You may require a mount designed for super high vibration, like our "Mighty Mount" levelers, example shown here.

Anchorable mounts: All types of levelers can offer lag bolt holes, enabling the leveling foot to be secured to the floor or platform with bolts. There is also the option of a specially configured base (teardrop shape) with hole for mounting bolt, like the PolyMount shown here. The advantage of this type of foot is that it prevents "walking" of the machine. Disadvantage is that more effort is required if you want to move the equipment. Also, if you are dealing with high vibration levels, holes can add additional stress to the base and possibly result in failure.

There are also a variety of types of levelers geared for particular requirements, including:

Glides: These are designed with a pad or base material that allows the supported equipment to be easily moved by sliding. This type of foot permits easily movement and relocation. Glide base material is typically harder and more abrasive-resistant than an anti-vibration base. Downside is that vibration can cause walking and movement. Shown here is one of our Glide-Rite mounts, which offer a nylon or elastomer pad.

Low-profile design: This type of mount is used when equipment height is restricted, and permits equipment to sit lower to floor or platform. Con is that weight distribution in the pad may be limited due to thinner material. Our LP 100, illustrated here, is a low profile mount available in many variations.

Low-cost: Sometimes weight, vibration, and unevenness are not worries, and you simply need an inexpensive foot to do the job. In that case a simple leveler of one-piece design can provide cost savings, like our Rattle Mounts.

Well, that gives you a mounting number of issues to consider in selecting the right leveling device for your application. Check out even more options in our Leveling Elements section. And if you have special issues or concerns, by all means contact our Technical Sales Associates (800-877-8351) and we'll be glad to assist. We'll do everything but "foot" the bill, and that's on the "level."

Okay, now I'm even driving myself crazy with these puns!

GN 115-NI Stainless Steel Door Locking Mechanisms

2009-04-06T07:49:00.004-06:00

Diane reporting, with our latest featured product, our new series GN 115-NI Stainless Steel Door Locking Mechanisms in metric sizes.

These RoHS-compliant locks are an economical design and offer a straightforward locking action, rather than a locking and clamping action. The knob, lock housing and hardware are all constructed of stainless steel, making this lock an excellent choice for corrosive environments. The choice of nine differently-shaped catch plates provides a range of latching distances from 6 to 28 mm or .236 to 1.10 inches.

For more door-locking mechanisms, please see our catalog Section 3, which features pull handles and access hardware.

Nuts and Bolts and Pitch, Oh My!

2009-04-02T10:12:00.001-06:00

Sometimes it's the little things, as all engineers know. The functionality of the most immense, complicated machinery can be compromised by failure of something as small as a nut.

Diane reporting today, here to share with you some more helpful information we provide in our Web site's Technical Section. If you're struggling with spec'ing in metric fasteners and need to know about size options, pitch, and drill sizes, we've got the table for you: check out our Metric Thread Pitch Table.

And while you're at it, take a look at our Limits for Metric (Standard) Coarse Threads for bolts table. It has everything you need to know about the specs for metric bolts, including normal engagement length, major diameters, pitch diameters, and minor diameters for standard metric thread sizes M 1-M 39.

Meanwhile, we have an equivalent table for metric nuts as well.

Just a reminder that you can see all the treasures available in our Technical Section HERE.
