    摘要: An electric actuator (13) comprises a housing (17) which contains a screw mechanism (11) and an electric motor (5) which is driveably connected to the screw mechanism (11) which provides a linear movement in response to a rotational movement of the electric motor (5), said screw mechanism (11) comprising a screw (12) and a nut (33) one of which is supported rotatably with respect to the housing (7) by means of an angular contact ball bearing (31), said screw (12) by means of an intermediate coupling element (18) engaging an actuating member (16) for transferring axial forces. The intermediate coupling element (18) engages the screw (12) by means of an axial connection (53, 54) which allows radial movements.
