Roller bearing cage, has contour designed such that maximum diameter and guide regions are present at discrete number of points, where radii of regions of cage are smaller than radius of board, so that tapering gap results in slide bearing

摘要

The cage has rolling body bags guided to boards of an outer bearing ring at its outer surface. An S-shaped outer contour (5) of the cage is non-circularly designed such that maximum diameter (1) and guide regions (2) are present at a discrete number of points, which are evenly distributed over a periphery, where the outer contour between the guide regions is reduced in the diameter. Radii of contact regions are smaller than radius of the guide board of the outer ring, so that a tapering gap results in a slide bearing.
