Abstract: Ball screw, having a spindle nut (2) which may be provided on a recirculating ball screw (1) and on the inner circumference of which turns (3) of ball grooves (4), helically wound around an axis, are provided in which balls (5) can roll, at least one return element (8), arranged on the outer circumference of the spindle nut (2) and provided with a return duct (9) for the balls (5), at its two ends connecting a start of a turn (3) to an end of a turn (3) in order to permit a continuous recirculation of the balls (5), the return element (8) between its two ends being supported on a support (15, 21), the return element (8) being resiliently supported by means of at least one spring element (14) on the support (15, 21).

Abstract: A combined radial and axial bearing is defined by the fact that the bearing ring (1) of the radial bearing is held at an axial end by a mounting bore in the runner plate (2) of the axial bearing, and the positively locking engagement is brought about by means of a ring (3) which is arranged between the bearing ring (1) and runner plate and is configured in such a way that the bearing ring (1) and runner plates (2) are prevented from rotating with respect to one another in the circumferential direction but limited axial displacement is possible.
