Play between an axially pre-tensioned ball bearing assembly mounted on a rotating motor shaft and the bore of the motor's end shield, in which the bearing is received, is prevented by use of a disc having a formed-on, wedge-shaped rim, which is pressed into the space between the bearing's outer surface and the wall of the bore. Centering for the pretensioning spring can be provided by an oppositely protruding, wedge-shaped rim, also formed on the disc at the time of manufacture.
