ABSTRACT:
A combination bearing and apparatus for maintaining the relative axial location of the input and output members of a camshaft phase change device. Peripheral grooves are formed in the members to receive a plurality of balls which support the input member for rotation on the output member. Radial slots are formed in the output member for insertion of the balls, and the angular position of the balls is maintained by fingers formed on a retention member which has spoke members received in the slots, and which is held in engagement with the output member by a retaining ring.
