Screw Jack Systems offer comprehensive lifting and positioning style 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, motion control, safety, and protection components to provide a complete bundle from a single source.
We offers system design assistance, taking the guess work out of item selection. Our years of application experience assures that elements of the design process are considered. We also offer complete 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 versions 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 designed to specification.
The jack housings are made from ductile iron and proportioned to support the rated capacity of the unit. 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 equipment (drive sleeve). The worm shaft is backed 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 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 higher strength bronze worm gear (drive sleeve). The worm shaft is backed on anti-friction tapered roller bearings with exterior seals provided to prevent lack 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 
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-artwork CAD and CAE systems and adhering to stringent production requirements, these screw jacks fulfill all the required safety, cost-efficiency, and strength mandates of the application.
