Screw Jack Systems offer extensive lifting and positioning style solutions for a wide selection of industries. Highly accurate and intensely dependable machine screw and ball screw jacks are matched with an comprehensive range of drive, connection, motion control, safety, and security 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 look process are believed. We also offer full assembly drawings, which provides 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 plans. There are no “regular” 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 unit. MJ, 1/4 ton, and 1/2 ton models have light weight aluminum housings.

Each Worm Gear Screw Jack incorporates an alloy metal 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 prevent lack of lubrication (sealed radial bearings on the MJ, 1/4 , 1/2, and 1 ton systems). The drive sleeve can be 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 steel worm which drives a higher strength bronze worm gear (drive sleeve). The worm shaft is supported on anti-friction tapered roller bearings with external seals provided to prevent lack of lubrication. The drive sleeve can be 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 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 worm screw jack production requirements, these screw jacks meet all the required safety, cost-efficiency, and durability mandates of the application.
