Screw Jack Systems offer comprehensive lifting and positioning design solutions for a wide variety of industries. Highly accurate and intensely dependable machine screw and ball screw jacks are matched with an comprehensive range of drive, connection, motion control, safety, and protection components to supply a complete package from a single source.
We offers system style assistance, taking the imagine work out of item selection. Our years of software experience assures that elements of the design process are considered. We also offer complete assembly drawings, which provides time saving value and guarantees the right system components are integrated into your design.
Worm Equipment Screw Jack systems are ruggedly designed and stated in standard versions with load handling capacities from 1/4 ton to 100 tons. They might be used individually or in multiple arrangements. There are no “regular” travel lengths and all Worm Gear Screw Jack systems are designed 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 aluminium 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 external seals provided to prevent 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 supported on anti-friction tapered roller bearings with external 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, depending upon jack configuration.
The threads are precision formed, worm screw jack 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 production requirements, these screw jacks fulfill all the required safety, cost-efficiency, and sturdiness mandates of your application.
