Abstract
Abstract An anti-friction ball bearing assembly, adapted for mounting within a housing comprising an outer sleeve and an inner sleeve concentrically fitting within the outer sleeve, the inner sleeve having a central opening for the passage of a shaft therethrough, the inner sleeve having a number of tracks defining paths for the circulation of balls between the sleeves and the shaft during movement between the shaft and the bearing assembly, the balls, during a portion of their circulation path, contacting the shaft and the inner surface of the outer sleeve at a plurality of raceway surfaces provided thereon, the outer sleeve having on its outer surface at least one annular groove, an ''''O'''' ring disposed in the annular groove and in contact with the inner surface of the housing to accommodate misalignment between the housing and the shaft.
