screw jack

Screw Jack Systems provide extensive lifting and positioning style solutions for a wide variety of industries. Highly accurate and extremely reliable machine screw and ball screw jacks are matched with an considerable selection of drive, connection, motion control, safety, and protection components to provide a complete bundle from a single source.

We offers system style assistance, taking the imagine work out of product selection. Our years of app experience assures that elements of the design process are believed. We also offer full assembly drawings, which gives time saving worth and guarantees the right 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 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 made from ductile iron and proportioned to aid the rated capacity of the unit. MJ, 1/4 ton, and 1/2 ton models have aluminum housings.

Each Worm Gear Screw Jack incorporates an alloy steel worm which drives a high strength bronze worm gear (drive sleeve). The worm shaft is backed on antifriction tapered roller bearings with external seals provided to prevent loss of lubrication (sealed radial bearings on the MJ, 1/4 , 1/2, and 1 ton systems). The drive sleeve is usually 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 stainless steel worm which drives a high 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 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 manufacturing requirements, these screw jacks meet up with all the necessary safety, cost-efficiency, and durability mandates of your application.
