Screw Jack Systems offer comprehensive lifting and positioning design solutions for a wide variety of screw jack china industries. Highly accurate and intensely dependable machine screw and ball screw jacks are matched with an intensive selection of drive, connection, motion control, safety, and safety components to provide a complete bundle from an individual source.
We offers system design assistance, taking the imagine work out of product selection. Our years of software experience assures that elements of the look process are considered. We also offer full assembly drawings, which gives time saving value and guarantees the right system components are integrated into your design.
Worm Equipment Screw Jack systems are ruggedly designed and produced in standard models with load managing capacities from 1/4 ton to 100 tons. They might 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 constructed with ductile iron and proportioned to aid the rated capacity of the machine. MJ, 1/4 ton, and 1/2 ton models have aluminium 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 prevent lack of lubrication (sealed radial bearings on the MJ, 1/4 , 1/2, and 1 ton devices). The drive sleeve is definitely 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 backed 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 lead tolerance is approximately ±0.004″ per foot.
Designed with state-of-the-artwork CAD and CAE systems and adhering to stringent production requirements, these screw jacks satisfy all the necessary safety, cost-efficiency, and sturdiness mandates of the application.
