Screw Jack Systems provide comprehensive lifting and positioning style solutions for a wide variety of industries. Highly accurate and extremely dependable machine screw and ball screw jacks are matched with an considerable range of drive, connection, motion control, safety, and safety components to supply a complete package from an individual source.
We offers system design assistance, taking the imagine work out of item selection. Our years of app experience assures that all elements of the design process are considered. We also offer complete assembly drawings, which gives time saving value and guarantees the correct system components are built-into your design.
Worm Gear Screw Jack systems are ruggedly designed and stated in standard models with load handling capacities from 1/4 ton to 100 tons. They might be used individually or in multiple arrangements. 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 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 high strength bronze worm gear (drive sleeve). The worm shaft is supported 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 supported on antifriction tapered roller or ball thrust bearings. Rotation of the drive sleeve causes the lifting screw to translate or rotate, dependant on 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 prevent lack 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, 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 satisfy all the required safety, cost-efficiency, and toughness mandates of the application.
