Abstract: A ball screw which has a threaded nut arranged on a threaded spindle, a helical ball channel in which balls are arranged delimited by ball grooves of the threaded spindle and the threaded nut, a ball cage which receives the balls and a spring element which bears with one end against the threaded nut and with another end against the ball cage. The spring element is arranged axially adjacent to the ball cage in an annular gap delimited by the threaded nut and the threaded spindle.

Abstract: A suspension actuator (1) for positioning a movably mounted component of a motor vehicle suspension, including a first actuator component (4), which is to be connected to the movably mounted component, and a second actuator component (3), which is to be connected to a fixed suspension component, wherein both actuator components can be axially adjusted relative to one another via a ball-type linear drive (5), which includes a threaded spindle (6) and a nut (7) running thereon. Either the nut can be driven via a drive motor (10) for the axial adjustment of the threaded spindle or the spindle can be driven via a drive motor for axial adjustment of the nut.

Abstract: A ball-screw drive, which has a spindle nut arranged on a threaded spindle and an axial bearing which is arranged so as to act on the threaded spindle and which has a bearing part arranged so as to be rotatable relative to the threaded spindle. The bearing part is arranged so as to be captively retained on the threaded spindle by a captive retention means.
