Abstract

In a roller bearing cage which holds the set of rollers in the raceway of aninner ring to form a structural unit, the lateral rings are interrupted by slots. Webs extend between the lateral rings. In this way, the cage gives way radially, which makes it possible to push the rollers over one of the flanges of the inner ring to assemble the bearing. To stabilize the cage during operation, projections are provided on the webs, which, as needed, contact the raceway of the outer ring and secure the radial position of the webs.
