Frequently Asked Questions

How do jack screws work?

Jack screws are gearbox assemblies (either worm gear or bevel gear) and transmission products (lead screw, ball screw or roller screw) that convert rotary motion to linear motion using a motor. They can push, pull, tension, lock, unlock, tilt, pivot, roll, slide, lift or lower loads weighing a few kilos to thousands of tonnes.

What standards do these jack screws comply with?

These jack screws are built in accordance with ISO EN standards for use in machinery, lifting tables and platforms.

What are the components of a jack screw?

  • The screw is the most important component.
  • It may be attached to a plate that houses load or to another piece of machinery that is then moved.
  • Instead of a plate, an attached nut or nut flange is sometimes used, so that the screw remains stationary and only the nut assembly moves.
  • There is also a fixed base unit that houses the gears.
