Screw Jack Systems provide 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 protection components to provide a complete package from an individual source.
We offers system style assistance, taking the imagine work out of item selection. Our years of program experience assures that all elements of the look process are considered. We also offer complete assembly drawings, which gives time saving worth and guarantees the correct system components are built-into your design.
Worm Equipment 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 separately 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 made from 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 metal 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 avoid loss of lubrication (sealed radial bearings on the MJ, 1/4 , 1/2, and 1 ton devices). 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 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 avoid lack of lubrication. The drive sleeve is usually 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 Course 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 meet up with all the required safety, cost-efficiency, and strength mandates of the application.
