摘要: An electric actuator (13) comprises a housing (7) which contains a screw mechanism (11) and an electric motor (5) which is driveably connected to the screw mechanism 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 (13) one of which is supported rotatably with respect to the housing (17) by means of an angular contact ball bearing (31), said angular contact ball bearing (31) comprising two pairs of contact points the working lines (40,41) of which intersect each other. One pair of contact points has a working line (41), the angle of which with respect to the axis (42) of the bearing (21) is smaller than the corresponding angle of the other working (40) line.
