Screw Jack Systems offer extensive lifting and positioning style solutions for a wide variety of industries. Highly accurate and extremely reliable machine screw and ball screw jacks are matched with an intensive 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 guess work out of product selection. Our years of software experience assures that elements of the design 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 models with load managing capacities from 1/4 ton to 100 tons. They might be used individually or in multiple plans. There are no “standard” travel lengths and all Worm Gear Screw Jack systems are built to specification.
The jack housings are made from ductile iron and proportioned to aid the rated capacity of the machine. MJ, 1/4 ton, and 1/2 ton models have aluminium housings.
Each Worm Gear Screw Jack incorporates an alloy steel worm which drives a higher 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 products). The drive sleeve is usually 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 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 satisfy all the required safety, cost-efficiency, and durability mandates of your application.
