Screw Jack Systems offer comprehensive lifting and positioning design screw jack china solutions for a wide selection of industries. Highly accurate and intensely reliable machine screw and ball screw jacks are matched with an extensive selection of drive, connection, motion control, safety, and security components to provide a complete bundle from an individual source.

We offers system style assistance, taking the imagine work out of item selection. Our years of application experience assures that all elements of the design 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 Gear Screw Jack systems are ruggedly designed and produced in standard models with load managing capacities from 1/4 ton to 100 tons. They might be used separately 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 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 backed on antifriction tapered roller bearings with exterior seals provided to avoid lack of lubrication (sealed radial bearings on the MJ, 1/4 , 1/2, and 1 ton products). The drive sleeve is definitely backed 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 steel worm which drives a high 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 usually 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 business lead tolerance is approximately ±0.004″ per foot.
Designed with state-of-the-artwork CAD and CAE systems and sticking with stringent manufacturing requirements, these screw jacks fulfill all the required safety, cost-efficiency, and toughness mandates of your application.
