Screw Jack Systems provide extensive lifting and positioning style solutions for a wide selection of screw jack china industries. Highly accurate and intensely reliable machine screw and ball screw jacks are matched with an intensive range of drive, connection, movement control, safety, and safety components to supply a complete bundle from an individual source.
We offers system design assistance, taking the guess work out of product selection. Our years of program experience assures that elements of the look process are believed. We also offer complete assembly drawings, which gives 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 might 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 of 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 equipment (drive sleeve). The worm shaft is supported on antifriction tapered roller bearings with external seals provided to prevent lack of lubrication (sealed radial bearings on the MJ, 1/4 , 1/2, and 1 ton products). The drive sleeve can be 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 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 avoid 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 Course 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 production requirements, these screw jacks satisfy all the required safety, cost-efficiency, and sturdiness mandates of the application.
