Stainless steel screw jack SWL stainless steel screw jacks are specifically designed for positioning and lifting applications that are located in wet, corrosive and harsh environments. Metallurgical properties of stainless steel allow it to remain ductile even atvery low temperatures.All exposed surfaces and components feature stainless steel or bronze construction Nitrile rubber seals protect all internal mechanisms.

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. Working Principle of Screw Jacks 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.
