ABSTRACT:
Material is first formed into a flat ring. Ball retaining pockets are then formed in the flat ring leaving bridge material between adjacent pockets. Bearing balls are inserted into the ball retaining pockets and bridge material between adjacent pockets is then reshaped such that the bridge material wraps partially around the balls, thereby retaining the balls and forming a rigid bridge between adjacent ball pockets. The bridge is proximate a line common to the centers of adjacent balls.
