Screw Jack Systems offer extensive lifting and positioning style solutions for a wide variety of industries. Highly accurate and intensely dependable machine screw and ball screw jacks are matched with an comprehensive range of drive, connection, movement control, safety, and safety components to provide a complete package from an individual 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 believed. We also offer full assembly drawings, which 
gives time saving value 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 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 made of ductile iron and proportioned to support 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 higher strength bronze worm gear (drive sleeve). The worm shaft is supported 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 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 supported on anti-friction tapered roller bearings with exterior 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 business lead tolerance is approximately ±0.004″ per foot.
Designed with state-of-the-art CAD and CAE systems and adhering to stringent production requirements, these screw jacks fulfill all the necessary safety, cost-efficiency, and sturdiness mandates of the application.
