Acme Screw Jack

Screw Jacks

1/4 to 350 ton capacity. Acme screw jacks offer positive mechanical action, precise positioning, and uniform lifting speeds. With both standard and custom engineered machine screw actuators.

Features & Benefits
  • Multiple Configurations
    Standard configurations include upright or inverted units with translating or rotating lifting screws, and top plate, threaded, or clevis ends.
  • Precise Positioning
    Controlled accurately for positioning within thousandths of one inch
  • Self Locking
    Models featuring higher gear ratios are inherently load holding as long as the actuator is not subject to vibration
  • Uniform Lifting Speeds
    Since many actuators feature the same gear ratios different capacities can be used in the same application to lift unevenly distributed loads with uniform speeds
  • Quick, Sure Operation
    All actuators are designed and built to be positive acting, for accurate response to motive power
