Screw Jack Systems offer 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 considerable 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 item selection. Our years of app experience assures that elements of the look process are considered. We also offer full assembly drawings, which provides time saving worth and guarantees the right system components are built-into your design.
Worm Equipment Screw Jack systems are ruggedly designed and stated in standard models with load handling capacities from 1/4 ton to 100 tons. They might be used individually or in multiple arrangements. There are no “standard” travel lengths and all Worm Gear Screw Jack systems are designed to specification.
The jack housings are constructed with 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 gear (drive sleeve). The worm shaft is supported on antifriction tapered roller bearings with external seals provided to avoid loss of lubrication (sealed radial bearings on the MJ, 1/4 , 1/2, and 1 ton models). 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, depending upon 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 worm screw jack anti-friction tapered roller bearings with exterior seals provided to avoid loss of lubrication. The drive sleeve is usually 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 Class 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 production requirements, these screw jacks fulfill all the required safety, cost-efficiency, and toughness mandates of your application.
