Screw Jack Systems provide comprehensive 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 considerable selection of drive, connection, motion control, safety, and safety components to supply a complete package from an individual source.

We offers system style assistance, taking the imagine work out of product selection. Our years of program experience assures that elements of the design process are believed. We also offer full assembly drawings, which gives time saving value and guarantees the right system components are worm screw jack integrated into your design.
Worm Gear 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 individually or in multiple plans. There are no “regular” travel lengths and all Worm Gear Screw Jack systems are designed to specification.
The jack housings are constructed with ductile iron and proportioned to support the rated capacity of the unit. MJ, 1/4 ton, and 1/2 ton models have aluminium 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 backed on antifriction tapered roller bearings with external seals provided to avoid lack of lubrication (sealed radial bearings on the MJ, 1/4 , 1/2, and 1 ton units). The drive sleeve is certainly supported 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 external seals provided to avoid loss 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 Class 2-C (Centralizing) tolerances. Jack lift shaft lead tolerance is approximately ±0.004″ per foot.
Designed with state-of-the-art CAD and CAE systems and adhering to stringent manufacturing requirements, these screw jacks satisfy all the necessary safety, cost-efficiency, and durability mandates of your application.
