Duff-Norton Modular Actuators
Duff Norton modular actuators are made for a variety of applications. They are custom made by matching standard actuators with electric, air, hydraulic or explosion proof drive units.
Duff Norton translating tube machine screw models feature a traveling lift nut which allows precise load positioning. Translating tube actuators are used when environmental contamination is anticipated as they have an enclosed lifting screw and translating tube. For use in locations relatively free of dust, dirt and moisture.
Optional limit switches and transducers are available on the translating tube machine screw modular actuator.
Anode Heavy Duty Screw Jacks
Screw Jacks - 1/4 to 350 Ton
The Anode heavy-duty screw jack has been modified for high temperature loads found in the alumina smelting industry.
The worm gears are made of wear resistant bronze and are up to 40% larger than our standard versions. This anode screw jack also contains heavy duty seals that protect against very abrasive alumina dust. Anode screw jacks use only heat-treated alloy steel worms.
These heavy-duty screw jacks have a large overload capacity to handle the side loading stresses caused by the thermal expansions and contractions of the frames. They are also built to take the compressive overloads caused by occasional high jacking of the frames and frozen pots.
