A tripot universal joint has a plurality of roller assemblies mounted on trunnions of a drive shaft and run in longitudinal tracks of a housing. Each roller assembly includes a roller and a needle roller bearing for rotatably mounting the roller on a roller carrier. Each needle bearing includes a plurality of needle rollers and a cage. The cage has spaced end rings that are connected by a plurality of cross bars to retain the needle rollers with respect to the roller in the axial direction, and conformations that cooperate with the roller to retain the cage with respect to the roller in the axial direction.
