Screw Jack Systems offer extensive 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 comprehensive selection of drive, connection, movement control, safety, and protection components to supply a complete bundle from an individual source.
We offers system style assistance, taking the imagine work out of item selection. Our years of application experience assures that elements of the look process are considered. We also offer full assembly drawings, which provides time saving worth and guarantees the right system components are integrated into your design.
Worm Gear Screw Jack systems are ruggedly designed and produced in standard versions 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 built to specification.
The jack housings are made from ductile iron and proportioned to support the rated capacity of the machine. 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 high strength bronze worm equipment (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 systems). The drive sleeve is usually 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 avoid 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, dependant on jack configuration.
The threads are worm screw jack 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-artwork CAD and CAE systems and sticking with stringent production requirements, these screw jacks meet all the necessary safety, cost-efficiency, and sturdiness mandates of your application.
