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.
