A play-free radial ball bearing, includes an inner bearing ring and two outer bearing rings which are disposed in spaced-apart relationship and define a common raceway. A spring element applies an axial force on one of the outer bearing rings to thereby press the outer bearing rings resiliently against one another. The outer bearing rings and the spring element are surrounded by a tolerance ring which is made of plastic material to provide a structural unit, whereby the tolerance ring has a shoulder on one end for radially surrounding the spring element and at least one retaining lug on another end for radially surrounding the other one of the outer bearing rings.

Play-free radial ball bearing

A chiplessly made angular contact bearing comprising an outer ring (,) and an inner ring (,) is configured as a self-retaining unit by the fact that the inner ring (,) comprises uniformly spaced resilient retaining tabs (,) which, as viewed in longitudinal cross-section, comprise two sections (,) that are disposed angularly relative to each other and separated by a vertex (,), the diameter of the retaining tabs (,) is largest at the vertex (,) and the diameter of the axially outer section (,) of the retaining tabs (,) is smaller than the inner diameter of the outer ring (,).
