ABSTRACT:
The present invention provides a method and apparatus for retaining bearing balls in a bearing assembly. For example, a cage assembly may comprise an annular cage having a plurality of pockets in which to snap-in bearing balls via openings having a width less than the diameter of the bearing balls. A retainer ring for the cage may have an inner diameter that is equal to the inner diameter of the cage. The cage assembly may comprise a plurality of cage webs, wherein each cage web is located between two adjacent pockets, and each cage web may be tapered (either radially, axially, or both radially and axially). The plurality of cage webs may be tapered such that the cage webs are tapered towards a distal end of each cage web and away from a proximal end of each cage web. An outer land may pilot the bearing assembly.
