摘要： A hybrid bearing cage, suitable for high-speed applications, includes a plastic ring and a metal stiffener. Rollers, such as balls, are retained in roller retainers in the plastic ring. The roller retainers are joined by links. The metal stiffener has an annular portion and a plurality of radial extensions that extend over the links, reducing deflection and stress concentrations in the plastic ring due to centrifugal forces.

摘要： A cage for a rolling bearing assembly with optimized contact surfaces to reduce friction between the cage and the adjacent contact surfaces is disclosed. The rolling bearing assembly includes a radially inner bearing ring including a radially inner race defined on a radially inner rolling element facing surface, a radially outer bearing ring including a radially outer race defined on a radially outer rolling element facing surface, and a plurality of rolling elements supported to roll between the radially inner race and the radially outer race. The cage includes a first rim including a first rolling element guide surface facing a plurality of rolling elements. A first outer surface facing away from the first rolling element guide surface includes a first outward projection. In another embodiment two bearing assemblies are provided, and each of the bearing assemblies includes a cage with optimized contact surfaces.

摘要： A bearing, including: an inner ring defining a first groove; an outer ring including a radially inner surface, the radially inner surface facing an axis of rotation of the bearing and defining a second groove and a third groove; a cage radially disposed between the inner ring and the outer ring; a plurality of balls retained by the cage, and disposed in the first groove, and in the second groove; and a preloaded resilient washer assembly including a rigid washer and a resilient washer including a radially outermost surface disposed in the third groove. The resilient washer urges the rigid washer away from the outer ring in an axial direction parallel to an axis of rotation of the bearing.
