Abstract
A bearing device for a threaded spindle has a bearing housing with at least one receptacle configured to receive a bearing part of the threaded spindle. The at least one receptacle is a clamping bushing securing the bearing part by electromechanical elements or fluid-operated elements. The clamping bushing has a wall that is elastically deformable by a pressure medium. The wall and the bearing housing define an annular chamber configured to receive the pressure medium. A control unit is provided to control the pressure of the pressure medium and thus the clamping action of the clamping bushing.
