A mounting sleeve particularly for the loose annular parts of a multi-row anti-friction bearing wherein the rows of rolling bodies are toward the axial ends of the outer ring. The mounting sleeve is approximately U-shaped with a slit opening of about 90.degree. in it extending along the sleeve. At axially opposite ends of the U-shaped sleeve are formed radially inwardly directed flanges which extend over a smaller circumferential angle than the sleeve, e.g. over an angle of about 180.degree., and are each symmetric around the U-shaped sleeve. Projections on the axial insides of the flanges rest axially either against the row of rolling bodies or against the separators for the row of rolling bodies. A radially outward projection opposite the slit opening in the sleeve aids in installation and removal of the sleeve.

Mounting sleeve for anti-friction bearing

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.
