Needle rollers are equally spaced means of 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 utilized with lipped washer to serve as raceway surface 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.
