Abstract
A light weight bearing cage assembly (100) consisting of a plurality of snap-on bridge elements (104) coupled between first and second cage support rings (102A, 102B) conforming to the surfaces of adjacent rolling elements (10). The snap-on bridge elements maintain rolling element (10) in separation, provide rolling element retention within the bearing assembly, and function as a lubrication reservoir between the rolling elements for grease lubricated bearings. Each snap-on bridge element may be individually removed and replaced by snap-on engagement with the first and second cage support rings. Optional locking clips or rings (300, 302) fitted over each snap fitting end of the bridge elements optionally provides additional security against accidental uncoupling of the bridge elements from the first and second cage rings.
