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 extensive selection of drive, connection, motion control, safety, and security components to supply a complete package from a single source.
We offers system design assistance, taking the guess work out of item selection. Our years of software experience assures that elements of the look process are considered. We also offer full assembly drawings, which provides time saving value and guarantees the correct system components are built-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 might 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 constructed with 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 higher strength bronze worm equipment (drive sleeve). The worm shaft is backed on worm screw jack 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 systems). 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 worm which drives a higher 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 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, depending upon jack configuration.
The threads are precision formed, typically using Class 2-C (Centralizing) tolerances. Jack lift shaft 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 meet up with all the required safety, cost-efficiency, and sturdiness mandates of your application.
