New Three-Ton Machine Screw Actuator From Duff Norton Excels In Positive Mechanical Positioning Applications

Charlotte, NC - Duff Norton has been experiencing high demand for this key capacity for some time and is pleased to officially release the new actuator to industry. For applications requiring positive mechanical positioning the new three-ton actuator is the ideal solution.

The new three-ton capacity machine screw actuator has a standard 24.2 efficiency rating, can be driven at 2 horsepower maximum, and is available with Top Plate, Clevis End, or Threaded End mounts.

The actuator can be driven either by a manual crank or via gear motor, which is connected, to the horizontal worm shaft.
