Jack Screws

Palmgren jack screws are designed for lifting loads, pushing & pulling mechanical equipment and moving / adjusting the tight clearance of mechanical parts in applications requiring linear motion. Choose from a wide range of these screws, available in male and female thread variants on Raptor Supplies.

Features

  • Jack screws, also known as screw jacks, are linear motion actuators that are frequently used to lift or move loads.
  • They are used in applications requiring linear motion or pushing / pulling along a linear axis.
  • Each jack allows quick-acting height adjustment via a fine adjusting screw.
  • These screws have a self-locking feature for movement prevention and secure positioning.

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.
