   Screw Jack

Screw jack is used in applications where linear motion is required. Lifting of any load, pushing or pulling of mechanical equipment, adjusting of tight clearances of mechanical parts can be done by screw jacks. Mechanical capacity of screw jacks is between 5kN and 2000kN. Jack screws can be used as linear motors, linear actuators, or mechanical lifts depending on type of motion. Screw Jack Turkey

How Screw Jacks Work ?

Main components of screw jacks are; trapezoidal lifting screw, worm screw, worm gear and gear housing. Worm screw is rotated manually or by motor. Worm gear is rotated by worm screw. The lifting screw moves through the rotating worm gear. The linear motion speed of lifting screw depends on thread size and rotation ratio of worm gears.

In some models of jack screws, The lifting screw does not move up and down. It only rotates around its axis. A lifting nut (also known as travelling nut) moves along the screw. The lifting nut of jack screw is made of bronze to decrease friction.
