Screw Jack Systems offer extensive lifting and positioning style solutions for a wide variety of industries. Highly accurate and extremely dependable machine screw and ball screw jacks are matched with an extensive selection of drive, connection, motion control, safety, and safety components to supply a complete package from an individual source.

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

Each Worm Gear Screw Jack incorporates an alloy metal worm which drives a high strength bronze worm gear (drive sleeve). The worm shaft is backed on antifriction tapered roller bearings with external seals provided to avoid loss of lubrication (sealed radial bearings on the MJ, 1/4 , 1/2, and 1 ton devices). The drive sleeve is usually supported on antifriction tapered roller or ball thrust bearings. Rotation of the drive sleeve causes the lifting screw to translate or rotate, depending upon jack configuration.
The Inch and Metric Worm Gear Machine Screw Jacks incorporate an alloy or stainless worm which drives a high strength bronze worm gear (drive sleeve). The worm shaft is backed on anti-friction tapered roller bearings with external seals provided to avoid lack of lubrication. The drive sleeve is certainly 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 Course 2-C (Centralizing) tolerances. Jack lift shaft lead tolerance is approximately ±0.004″ per foot.
Designed with state-of-the-artwork CAD and CAE systems and sticking with stringent production requirements, these screw jacks meet all the required safety, cost-efficiency, and strength mandates of the application.
