Claim:
An actuator, comprising a gear unit and a motor unit, the gear unit having a gear housing and the motor unit having a motor housing and an internally located rotor with a drive shaft and an essentially cylindrical one piece bearing housing on the drive side, wherein the bearing housing protrudes, along with a bearing housed therein and the drive shaft ducted therein, into an opening in the gear housing, wherein the outside of the bearing housing and the inside of the opening in the gear housing have been geometrically mutually harmonized such that clamping points and tension-free places will form between them when the actuator has been assembled, and wherein a circumferential pretensioning force impacting on the bearing via the bearing housing is established by means of the clamping points at respective axial end areas of the bearing, wherein elevations are provided as clamping points on the outer circumference of the bearing housing, the elevations are located in a respective axial end area of the bearing.
