worm screw jack

Screw Jack Systems offer 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 comprehensive selection of drive, connection, movement control, safety, and security components to supply a complete bundle from a single source.

We offers system design assistance, taking the imagine work out of item selection. Our years of software experience assures that all elements of the design process are considered. We also offer full assembly drawings, which provides time saving value and guarantees the right system components are integrated into your design.
Worm Equipment Screw Jack systems are ruggedly designed and stated in standard versions with load handling capacities from 1/4 ton to 100 tons. They may 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 constructed with ductile iron and proportioned to support the rated capacity of the unit. MJ, 1/4 ton, and 1/2 ton models have aluminum housings.

Each Worm Gear Screw Jack incorporates an alloy steel worm which drives a high strength bronze worm gear (drive sleeve). The worm shaft is backed on antifriction tapered worm screw jack roller bearings with exterior 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 usually 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 exterior 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, dependant on 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 adhering to stringent manufacturing requirements, these screw jacks meet up with all the required safety, cost-efficiency, and durability mandates of the application.
