Duff Norton has introduced a new addition to its existing ball screw actuator line up. The new one-ton capacity ball screw actuator has a standard 23.1% efficiency rating, can be driven at half the maximum horsepower, and is available with top plate, clevis or threaded end mounts. As the horizontally mounted worm shaft turns, sliding contact is made with a worm gear inside the actuator housing. The worm gear is attached to a ball nut fitted with re-circulating steel balls that makes translating contact with the ball screw, reducing friction to a minimum and converting torque to thrust. The positive action of the low friction ball screw, which has also been heat treated for less wear, and nut design provides longer life at load and requires less power to achieve a specified thrust.
