HD series helical gear reducer 90 degree gearbox

A screw jack system is where more than one screw jack is operated in unison to achieve a linear movement. The screw jack system arrangement is also commonly referred to as a “screw jacking system”.

Electric screw jacks can also be called electric screw jacks, which include worm gear jacks and electric motors. 

Sluice gate is a common application for Trapezoidal Screw Jacks.

Worm Gear Screws Jacks can provide long duty life, high load capacity and flexible design. They come in two major categories, Ball Screw and Machine Screw.

The Crank Handle Screw Jack are ideal solutions for applications where electricity or power generators is inconvenient or dangerous, light weight, low duty cycle, low target cost and short travel length. The working principle of the hand operated worm gear screw jack is that the worm (also called the input shaft) is manually rotated by the hand wheel, the worm wheel is rotated by the worm, and the trapezoidal lifting screw is moved by the rotating worm wheel. The linear motion speed of the worm wheel manual screw jack trapezoidal lifting screw depends on the thread size and the worm gear speed ratio. Hand Operated Screw Jack is composed of hand wheel or hand crank and a worm gear screw jack.It is ideal solutions for applications where electricity or power generators is inconvenient or dangerous.

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.

This Micro cubic screw jack is special with a customized screw head.
