Features and Benefits

  • Environmental Protection
    The anode heavy-duty screw jack contains heavy duty seals that protect against very abrasive alumina dust.
  • Exceptional Wear Resistance
    Anode screw jacks use only heat-treated alloy steel worms.
  • Large Overload Capacity
    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.
  • Increased Durability
    They are built to take the compressive overloads caused by occasional high jacking of the frames and frozen pots.
  • Mechanical Advantage
    Oversized worm and gear set
  • High Temperature Resistance
    Engineered to withstand extreme heat using high temperature resistant grease
  • Configuration Options
    Translating or rotating models available
