Screw Jack Systems offer extensive lifting and positioning style solutions for a wide selection of industries. Highly accurate and extremely reliable machine screw and ball screw jacks are matched with an extensive range of drive, connection, movement control, safety, and protection components to provide a complete package from an individual source.
We offers system design assistance, taking the guess work out of product selection. Our years of application experience assures that all elements of the look process are considered. We also offer complete assembly drawings, which gives time saving value and guarantees the correct system components are integrated 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 may be used individually or in multiple plans. 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 light weight aluminum 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 supported on antifriction tapered roller bearings with exterior seals provided to avoid loss of lubrication (sealed radial bearings on the MJ, 1/4 , 1/2, and 1 ton models). The drive sleeve is certainly backed 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 higher strength bronze worm gear (drive sleeve). The worm shaft is supported on anti-friction tapered roller bearings with exterior seals provided to avoid 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 adhering to stringent production requirements, these screw jacks meet up with all the necessary safety, cost-efficiency, and sturdiness mandates of your application.
