A linear actuator ( 1 ) comprising a housing ( 6 ), a motor ( 2 ) comprising a stator with coils ( 4 ), a screw-nut system, and a rotor ( 5 ) axially and radially supported on the motor side by a bearing ( 11 ). The bearing comprises a ball ( 14 ) rigidly attached to the rotor, a cylindrical cavity ( 15 ) formed or positioned in the housing into which the ball ( 14 ) is inserted. A stop ( 17 ) is positioned in the cavity, supported in an axial direction of the rotor, against the ball ( 14 ) in essentially one point.
