Abstract

A device for level adjustment for a motor vehicle includes a ball screw. The screw nut of the ball screw is driven by an electric motor. The spindle of the ball screw is displaceable with respect to a housing. The ball screw is supported with respect to the housing using two axial self-aligning bearings with a common pivot point such that the housing can pivot with respect to the spindle, thereby avoiding loads on the balls of the ball screw.
