Screw Jack Systems offer comprehensive 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 extensive selection of drive, connection, motion control, safety, and security components to provide 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 elements of the design process are considered. We also offer complete 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 produced in standard models with load managing capacities from 1/4 ton to 100 tons. They may be used separately or in multiple arrangements. 
There are no “regular” travel lengths and all Worm Gear Screw Jack systems are designed to screw jack china specification.
The jack housings are made of 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 steel worm which drives a higher strength bronze worm gear (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 devices). 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, 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 external seals provided to prevent lack of lubrication. The drive sleeve is definitely 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 manufacturing requirements, these screw jacks meet all the necessary safety, cost-efficiency, and strength mandates of the application.
