<p>An actuator (10) has a linearly elongate frame (12), side (14a,b), end (16,17), and top covers (18) detachably and selectively mounted on side surfaces of the frame, a table mechanism (30) displaceable in the axial direction of the frame in response to energization of an electric motor (20), and a ball screw (24) for transmitting drive forces from the electric motor to the table mechanism. The operator can select various actuator configurations depending on the environment in which the actuator is to be installed and the application in which the actuator is to be used.</p> |
