Lude stainless steel screw jacks are specifically designed for positioning and lifting applications that are located in wet, corrosive and harsh environments.

Heavy Duty Worm Gear ACME Screw Jacks combine an acme screw jack, motor and gear reducer into a single compact unit.

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.

Screw jack/lift is a basis jack-up part, accomplish the functions such as lifting, drop, push and inverting through worm gear drives screw.

The Anti-Disengagement Bushing is a safety device preventing the translating trapezoidal screw from disengaging from the Screw Jack in the event of an accidental overstroke. The  AntiDisengagement Bushing features a trapezoidal thread which guarantees the full load support during the attempted overstroke.
