Abstract
A cage for lipless roller bearings, in which two rows of bearings are separated and supported by a support ring that is wedge- or cusp-shaped in cross-section at the longitudinally inward ends of the roller rows. The support ring surfaces facing the roller ends are so shaped (e.g. having a surface that is inclined to the roller end, or having a larger radius of curvature than the curved roller end, with the axes of curvature being placed inward of the roller axes) that there is defined a lubrication-receiving space between the support ring and the ends of the supported rollers which increases in width toward the radial interior of the bearing, to improve lubrication characteristics. Advantageously the cage may be used with a lipless self-aligning roller bearing, or a lipless conical or tapered roller bearing.
