Abstract
The invention concerns an operator assembly having a tubular housing extending along a central axis (X1) and a transmission mechanism arranged in an inner bore of the housing and extending along the central axis (X1). The transmission mechanism providing a screw with a threaded outer surface and a nut with a threaded inner surface. The nut is radially mounted around the screw and the inner thread is configured to cooperate with outer thread. The operator assembly further provides angular contact bearings that are radially arranged between the inner bore of the housing and an outer surface of the rotating nut to support in rotation and guide the nut within the housing. The angular contact bearings are axially adjacent and are disposed within an angular contact ball bearing and an angular contact roller bearing.
