A ball screw drive includes a lead screw for converting an auxiliary torque produced by an electric motor into an auxiliary translational force which acts on a steering rack in the steering system of a motor vehicle. One end of the lead screw and one end of the steering rack are each connected to a track rod via an axial link, and the ball screw drive has a ball nut mounted in a housing with a fixed bearing. In order to withstand lateral loads or lateral forces coming from the track rod or rods and acting in the radial direction, there is provided between an end of the lead screw connected to the track rod and the ball screw drive a plain bearing element which supports the lead screw radially against the housing.
