Abstract

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.
