Screw Jack Systems provide comprehensive lifting and positioning style solutions for a wide variety of industries. Highly accurate and intensely dependable machine screw and ball screw jacks are matched with an comprehensive selection of drive, connection, motion control, safety, and safety components to provide a complete bundle from an individual source.
We offers system style assistance, taking the guess work out of item selection. Our years of program experience assures that elements of the look process are considered. We also offer complete assembly drawings, which provides time saving worth and guarantees the right system components are integrated into your design.
Worm Equipment Screw Jack systems are ruggedly designed and stated in standard models with load managing 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 built to specification.
The jack housings are constructed with ductile iron and proportioned to aid 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 metal worm which drives a higher strength bronze worm gear (drive sleeve). The worm shaft is backed on antifriction tapered roller bearings with exterior seals provided to prevent loss of lubrication (sealed radial bearings on the MJ, 1/4 , 1/2, and 1 ton systems). The drive sleeve is backed 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 external seals provided to prevent 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 lead tolerance is approximately ±0.004″ per foot.
Designed with state-of-the-art CAD and CAE systems and sticking with stringent production requirements, these screw jacks fulfill all the worm screw jack required safety, cost-efficiency, and strength mandates of your application.
