Abstract
An actuator assembly includes an actuator with a cylinder-shaped shaft rotatable around an axially extending center axis (A), and the shaft includes an envelope surface. The assembly further provides a fixed, tubular bearing surrounding a section of the shaft, the bearing having an inner surface facing the envelope surface of the shaft so that an interface between the shaft and the bearing is created. The interface provides at least one circumferential groove and at least one complimentary circumferential ridge. The groove is arranged in the one of the envelope surface of the shaft and the inner surface of the bearing and the complimentary ridge is arranged in the other of the envelope surface of the shaft and the inner surface of the bearing.
