Screw Jack Systems offer extensive lifting and positioning design solutions for a wide selection of industries. Highly accurate and extremely reliable machine screw and ball screw jacks are matched with an considerable range of drive, connection, motion control, safety, and safety components to provide a complete bundle from an individual source.
We offers system style assistance, taking the guess work out of item selection. Our years of app experience assures that all elements of the look process are believed. We also offer complete assembly drawings, which provides time saving value and guarantees the right system components are integrated into your design.
Worm Gear Screw Jack systems are ruggedly designed and stated in standard models with load managing capacities from 1/4 ton to 100 tons. They might be used individually or in multiple arrangements. There are no “standard” travel lengths and all Worm Gear Screw Jack systems are designed to 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 aluminium housings.
Each Worm Gear Screw Jack incorporates an alloy steel worm which drives a high strength bronze worm equipment (drive sleeve). The worm shaft is supported on antifriction tapered roller bearings with exterior seals provided to avoid lack of lubrication (sealed radial bearings on the MJ, 1/4 , 1/2, and 1 ton systems). 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, dependant on jack configuration.
The Inch and Metric Worm Gear Machine Screw Jacks incorporate an alloy or screw jack china stainless worm which drives a higher strength bronze worm gear (drive sleeve). The worm shaft is supported on anti-friction tapered roller bearings with exterior seals provided to prevent lack 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, 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 adhering to stringent manufacturing requirements, these screw jacks fulfill all the required safety, cost-efficiency, and strength mandates of your application.
