Abstract
The invention concerns ball bearings which automatically take up play, are self-centering and self-adaptable to the stress. The bearing comprises an inner ring (1), an outer ring in two parts (2a, 2b), balls (3), an elastically yieldable element (4) and a case (5). One of the rings is formed of two parts (2a, 2b) which are relatively movably fitted together and some of the four rolling raceways along which the balls roll have set-back depressions arranged along their circumference. Application in particular in the automobile industry.
