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 selection of drive, connection, motion control, safety, and protection components to provide a complete bundle from a single source.
We offers system design assistance, taking the imagine work out of item selection. Our years of app experience assures that elements of the design 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 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 “standard” travel lengths and all Worm Gear Screw Jack systems are designed to specification.
The jack housings are made of ductile iron and proportioned to support the rated capacity of the machine. 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 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 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 loss of lubrication. The drive sleeve is 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 satisfy all the necessary safety, cost-efficiency, and sturdiness mandates of your application.
