Project Description

Quick Lifting Bevel Gear Screw Jack

The screw jack using bevel gear mechanism offers an extension to the range of uses of our precision screw jacks. As opposed to the worm gear screw jack, spiral bevel gear mechanism are used. So it offers higher efficiency and greater speed than other electro-mechanical screw jack. The duty circle up to 100% (continuous work).

As an added benefit, bevel gear jacks also act as miter boxes, making them an ideal choice for multi-jack systems. The range encompasses four sizes, with the transmission ratios 1:1, 2:1.

  • Available in machine and ball screw models
  • Threaded end conditions standard (load pad, clevis, and plain end condition available)
  • Protective boots and other options are available
  • Right hand and left-hand screw threads are available
  • Suitable for heavy duty cycle capabilities and multiple configurations.
