An electromechanical actuator arrangement (50) comprises an electromechanical motor (10) and a rail arrangement (35). The rail arrangement (35) has a rail (30) relative which the electromechanical motor drives in a main displacement direction (3). The electromechanical motor has electromechanically active actuators attached to a motor block (20) and are arranged to provide an actuating action against the rail. The rail arrangement has further at least one guide member (31) provided parallel to the main displacement direction. The guide members have a guiding surface (36) facing the motor block. The motor block in turn has guidance surfaces (37) facing the guiding surface of the guide members. The guiding surface or the guidance surface has a tangent line parallel to the main displacement direction. The other one of the guiding surface and the guidance surface has a tangent surface in a second plane parallel to the first plane
