<p>A high performance, two-piece cage for a ball bearing assembly includes a first annular member having a plurality of pockets and a second annular member that serves as a retaining ring to retain the balls in the first annular member. The pockets of the first annular member enclose an arc slightly greater than 180 degrees of each ball. Recesses in the second annular member, corresponding to the pockets of the first annular member, make point contact with the balls to urge the balls into position in the pockets. The limited arc of the pockets allows the first annular member to be removed from its mold, even when made of a brittle high temperature material. Second annular member can be made from a material different from that of the first annular member and can be made radially thinner than the first annular member to facilitate visual inflection of the ball bearing assembly.</p> |
