Our jacks were used in the first commercial aluminum-making plant in the United States and continue to be used in aluminum plants throughout the world.

The alumina smelting process involves high temperatures and loads. The Duff-Norton Mechanical Actuator | Heavy Duty | Anode Jack is a heavy-duty version of our standard actuator, and has been modified for each smelting facility's specific application.

The Duff-Norton Mechanical Actuator | Heavy Duty | Anode Jack's worm gears are made of wear resistant bronze and are up to 40% larger than our standard versions. Along with the larger worm gears are larger bearings and heavyduty seals. Sealing is very important because the alumina dust is very abrasive.

Duff-Norton Mechanical Actuator | Heavy Duty | Anode Jacks use only heat-treated alloy steel worms. Additionally, high temperature grease is used. These 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 highjacking of the frames and frozen pots.

Available in Imperial sizes
