Abstract
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.
