Abstract

A constant velocity universal joint including a housing having a plurality of longitudinally extending channels has an inner rotatable member having a plurality of radially disposed trunnions, each of which extends into a respective one of the channels. A ball and socket joint, including a ball member and a socket member, is disposed intermediate each trunnion and the housing. A bearing is located between each trunnion and the respective ball member to permit relatively frictionless axial movement between the trunnion and the respective ball member. The bearing includes a generally rectangularly shaped cage retaining a plurality of needle rollers on at least two of the sides of the cage. The central longitudinal axes of the needle rollers are disposed normally to the direction of axial movement of the trunnion with respect to the respective ball member.
