Abstract
A ball nut of a ball screw drive, in which the ball nut is mounted on a threaded spindle via balls. The ball nut has on its inner circumference a ball groove wound helically around an axis that extends over at least one winding, and a deflection body, with deflection ends, arranged on a circumferential face of the ball nut. The deflection ends engage into a recess of the ball nut, and adjoin an end and a start of the ball groove. The deflection body is supported on one side in radial directions and on the other side on a machine part. The deflection body is connected at its axial ends to bearings for mounting on the machine part. The bearings, which project circumferentially, engage into the recesses of the ball nut and are arranged with their bearing faces approximately flush with the outer circumferential face of the ball nut.
