Abstract

A play-free radial ball bearing in which the inner bearing ring is constructed in two parts, whereby at least one of the two bearing ring elements (4, 5) is axially and radially movable and the bearing outer ring (6, 23, 25) has a race (2) with a radius that is clearly larger that the radius of the bearing balls (1). Due to the significantly greater osculation of the outer race (2) in comparison to the bearing balls (1), a restricted tipping of the shaft with, at the same time, freedom from play in the bearing, is made possible in connection with the two part movable inner ring.
