Thrust needle roller bearings are components of small diameter needle rollers arranged in a spoke like configuration. Needle rollers are equally spaced by means of a cage whose 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 bearings can also be unitized with lipped washers which service as raceway surfaces for needle rollers. Washers can be supplied separately or can be mechanically unitized to needle roller bearings for ease of handling.Thrust Needle Roller bearings and Cage Assemblies
