Screw Jack Systems provide comprehensive lifting and positioning style solutions for a wide variety of industries. Highly accurate and extremely reliable machine screw and ball screw jacks are matched with an considerable selection of drive, connection, movement control, safety, and protection components to provide a complete package from an individual source.

We offers system style assistance, taking the guess work out of item selection. Our years of app experience assures that all elements of the look process are considered. We also offer complete assembly drawings, which gives time saving worth and guarantees the correct system components are integrated into your design.
Worm Equipment Screw Jack systems are ruggedly designed and produced in standard versions with load handling capacities from 1/4 ton to 100 tons. They might be used separately or in multiple arrangements. There are no “standard” travel lengths and all Worm Gear Screw Jack systems are built to specification.
The jack housings are constructed with ductile iron and proportioned to aid the rated capacity of the machine. MJ, 1/4 ton, and 1/2 ton models have light weight aluminum housings.

Each Worm Gear Screw Jack incorporates an alloy steel worm which drives a high strength bronze worm equipment (drive sleeve). The worm shaft is supported on antifriction tapered worm screw jack roller bearings with exterior seals provided to avoid loss of lubrication (sealed radial bearings on the MJ, 1/4 , 1/2, and 1 ton models). The drive sleeve is backed on antifriction tapered roller or ball thrust bearings. Rotation of the drive sleeve causes the lifting screw to translate or rotate, dependant on jack configuration.
The Inch and Metric Worm Gear Machine Screw Jacks incorporate an alloy or stainless worm which drives a higher strength bronze worm gear (drive sleeve). The worm shaft is backed on anti-friction tapered roller bearings with exterior seals provided to prevent lack of lubrication. The drive sleeve is supported on anti-friction tapered roller or ball thrust bearings. Rotation of the drive sleeve causes the acme thread lifting screw to translate or rotate, depending upon jack configuration.

The threads are precision formed, typically using Class 2-C (Centralizing) tolerances. Jack lift shaft business lead tolerance is approximately ±0.004″ per foot.
Designed with state-of-the-art CAD and CAE systems and sticking with stringent manufacturing requirements, these screw jacks meet all the necessary safety, cost-efficiency, and durability mandates of the application.
