Abstract
A bearing cage assembly comprising of a plurality of discrete bridge elements coupled between first and second cage support wire rings having selected tensions, and conforming to the surfaces of associated rolling elements. The discrete bridge elements maintain rolling element in separation, provide rolling element retention within the bearing assembly, and function as a lubrication reservoir for grease lubricated bearings. The discrete bridge elements may be disposed between adjacent rolling elements, or may be configured to pass through axial bores of hollow rolling elements.
