Product DescriptionProduct Info
Anti Block Design1

 

A-Split Gear Design

  • Best suited for light dynamic loads (1/3 jack capacity or less) and full jack capacity for static loads.
  • A split gear and dowel pins maintain gear alignment.
  • Adjustments are made by tightening the sleeve (housing) cap.
  • Typically reduces endplay to 0.010" — 0.015" without increased torque.
  • Available on Translating and KFTN models, 500-pound to 75-ton (upright and inverted).
  • Available on some keyed models.
  • Order using an “A” designation in the suffix of the part number.
Anti Backlash Design2

 

A90 Design

  • Best suited for medium dynamic loads (1/2 to 3/4 jack capacity) and full jack capacity for static loads.
  • This design incorporates a hardened steel plate pinned to the top of the internal gear and a secondary nut placed above the steel plate. Setting the backlash is accomplished by tightening the dog point set screws located inside the secondary nut.
  • The set screws are externally adjustable.
  • Typically reduces endplay to 0.008" — 0.012" without increased torque.
  • Available on upright translating models, 25-ton to 100-ton.
  • Order using an “A90” designation in the suffix of the part number.
Anti Backlash Design3

 

A95 Design

  • Capable of handling full jack capacity in dynamic as well as static conditions.
  • This design allows the gear teeth to remain intact and therefore retain their full load carrying capacity.
  • Adjust endplay by tightening the sleeve (housing) cap.
  • Typically reduces endplay to 0.008" — 0.012" without increased torque.
  • Available on upright and inverted translating models, 2-ton to150-ton.
  • Order using an “A95” designation in the suffix of thepart number.
