screw jack

Screw Jack Systems provide extensive lifting and screw jack china positioning design solutions for a wide variety of industries. Highly accurate and intensely dependable machine screw and ball screw jacks are matched with an intensive range of drive, connection, motion control, safety, and safety components to provide 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 believed. We also offer complete assembly drawings, which gives time saving worth and guarantees the correct 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 may 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 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 high strength bronze worm gear (drive sleeve). The worm shaft is supported on antifriction tapered roller bearings with exterior seals provided to avoid lack of lubrication (sealed radial bearings on the MJ, 1/4 , 1/2, and 1 ton devices). The drive sleeve is certainly 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 higher strength bronze worm gear (drive sleeve). The worm shaft is supported on anti-friction tapered roller bearings with external seals provided to prevent loss 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 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 sticking with stringent manufacturing requirements, these screw jacks fulfill all the required safety, cost-efficiency, and sturdiness mandates of your application.
