Abstract
A screw actuator (4) comprises a housing (1), a nut (5) and a screw (6) one of which is axially fixed with respect to the housing and the other of which is axially displaceable with respect to the housing for moving an head (21), as well as a motor (7) which comprises a stator (8) connected to the housing, and a rotor (9) which is drivingly connected to a rotatable part (6) of the screw actuator, the housing having a bore (10) accommodating at least the nut and/or screw, an axially fixed part of said nut or screw being supported with respect to a radial support abutment (11) which extends inwardly in the bore. The rotor of the motor is supported rotatably on a sleeve (13), said sleeve engaging the fixed part and extending away from the brake pad, said sleeve having a radially outwardly extending sleeve flange (14) which is interposed between said support abutment, and the axially fixed part.
