Features:
Needle roller and cage thrust assemblies are complements 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.
Designed to transmit thrust load between two relatively rotating objects while greatly reducing friction.
