These metric sized components are typically used on conveyor tracks, to enable a linear or rotary movement of heavy loads on those tracks. Three different versions are available: Type SBL, with a housing made of zinc plated, blue passivated sheet steel and a ball of plain finish steel; Type SNI, with a housing made of zinc plated, blue passivated sheet steel and a stainless steel ball; and Type NNI, with housing and ball both made of stainless steel. All types are RoHS compliant. The transfer units have a load capacity of 500 to 2000 N, depending upon size and type.
