Anode Jack Actuator

Rotating and Translating Inverted Style Anode Jacks

The Anode Jack was developed in partnership with the Aluminium Industry.

They were used in the first commerical aluminium making plant in the United States and continue to be used in aluminium plants throughout the world.

The Alumina smelting process involves high temperatures and loads.

The Anode jack is a heavy duty version of our standard actuator, and has been modified for each smelting facilities specific application.

The worm gears are made from wear resistant bronze and are up to 40% larger than standard versions. Along with the larger worm gears are larger bearings and heavy duty seals, sealing is very important becase the alumina dust is very abrasive.

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 high jacking of the frames and frozen pots.
