Flexible Coupling for Screw Jack System

Multiple screw jacks lifting system is composed of screw jacks and other jack accessories.

Pillow block is used for long connecting shaft for screw jack system.

Worm Gear Screw jacks can be motorised by connecting electric motors through a B14 flange or a B5 bell housing with coupling. 

Ball screw working principle is to turn the rotary movement into a linear motion, or linear motion into the ideal rotary motion products. So the ball screw jacks have high precision,reversible and efficient features.

An Electric Linear Actuator is an actuator that creates motion in a straight line, in contrast to the circular motion of a conventional electric motor.

SWL Stainless Steel Hand Crank Screw Actuator is a basic lifting component. It has many characteristics, such as compact structure, small size, light weight, wide power source, no noise, convenient installation, flexible use, multiple functions, various supporting forms, high reliability and long service life. It can be used alone or in combination. It can accurately control and adjust the height of lifting or propulsion according to a certain program. It can be driven directly by motor or other power or manually. It has different structure type and assembly type, and lifting height can be customized according to user's requirements.

Our high performance series typically has 50% greater duty cycle capabilities than the standard worm gear machine screw jack. So you get more from a machine screw jack before you need to upgrade to a ball screw jack.

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.
