Abstract
Disclosed herein is a bearing assembly comprising: an outer race having an inner surface; an inner race having an outer surface, the inner surface of the outer race and the outer surface of the inner race defining a bearing assembly raceway; a plurality of main rollers positioned within the bearing assembly raceway, the main rollers in contact with the inner surface of the outer race and the outer surface of the inner race; a plurality of mediate rollers positioned within the bearing assembly raceway counter-rotating with the main rollers such that each of the mediate rollers is in rolling contact with a pair of the plurality of main rollers; and a cage positioned in the bearing assembly raceway for at least partially bounding each of the mediate and main rollers. In one embodiment, the cage can be positioned within the bearing assembly raceway and comprises a cage body, the body having a plurality of parallel annular rims joined by a plurality of rungs, the rungs separated so as to define a plurality of main roller openings in the cage body for receiving the plurality of main rollers, the rungs having a plurality of mediate roller retainers extending from the rungs, the retainers …
