Screw Jack Systems provide comprehensive lifting and positioning design solutions for a wide variety of industries. Highly accurate and intensely reliable machine screw and ball screw jacks are matched with an considerable range of drive, connection, movement control, safety, and safety components to supply a complete package from an individual source.
We offers system design assistance, taking the imagine work out of item selection. Our years of software experience assures that all elements of the design process are considered. We also offer full assembly drawings, which gives time saving value and guarantees the correct system components are integrated into your design.
Worm Equipment Screw Jack systems are ruggedly designed and stated in standard versions with load handling screw jack china capacities from 1/4 ton to 100 tons. They might be used separately 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 made from ductile iron and proportioned to aid the rated capacity of the machine. MJ, 1/4 ton, and 1/2 ton models have light weight aluminum housings.
Each Worm Gear Screw Jack incorporates an alloy metal worm which drives a high strength bronze worm equipment (drive sleeve). The worm shaft is backed 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 products). 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 backed on anti-friction tapered roller bearings with exterior seals provided to prevent loss of lubrication. The drive sleeve can be 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 lead tolerance is approximately ±0.004″ per foot.
Designed with state-of-the-artwork CAD and CAE systems and sticking with stringent manufacturing requirements, these screw jacks meet up with all the necessary safety, cost-efficiency, and durability mandates of your application.
