About Mounting Tolerances Thrust Needle Roller And Cage Assembly

• Thrust needle roller and cage assemblies are complements of small diameter needle rollers, arranged in a spoke-like configuration.
• Needle rollers are equally spaced by means of a cage, its web section separates the rollers and provides guidance to keep them tracking in an orbital path.
• The purpose of these assemblies is to transmit a thrust load between two relatively rotating objects while greatly reducing friction.
• Thrust needle roller and cage assemblies also can be unitized with lipped washers to serve as raceway surfaces for the needle rollers.
• Washers can be supplied separately or can be mechanically unitized to the thrust needle roller and cage assemblies for ease of handling.
