Statewide Bearings supplies a range of high-quality linear motion screw jacks Australia-wide.
The generic term ‘screw jack,’ – or ‘jackscrew’ – generally refers to a product that utilises a gearbox assembly and a transmission medium (lead screw, ball screw or roller screw) which, through the use of a motor or hand wheel, converts this rotary motion into linear motion.
Screw Jack applications are endless, but screw jacks are traditionally used to pull, push, lock, tilt, pivot or lift and lower. The screw jack can be supplied using different ratios combined with different lead on the screws, thus offering a very large range of size and load capabilities. Literally anything from a few kilos to thousands of tonnes.
We can offer many screw jack (jackscrew) configurations from metric and imperial versions, ball screw jacks, acme screw jacks, electric screw jacks, bevel screw jacks, stainless jacks, upright, inverted, high duty cycle, plain or ball screw nuts, bellow protected and special coatings for specific environments. Even screw jack repairs subject to inspection.
