ABSTRACT:
A moveable cage which has a pattern of holes surrounding and concentric with a central axis of the cage, and a short hard pin located within the cage, and movable back and forth between the two ends of the cage. A single drive device attached to the cage causes both translation and rotation of the cage. As the cage is advanced and rotated, the interior pin is caused to move backward and forward as the balls roll over the surface of the pin, so that the wear on the balls and on the surface of the interior pin is evenly distributed.
