1ton Worm Gear Ball Screw Jack Price

A 1-ton worm gear ball screw jack is a high-efficiency linear actuator used to lift or position loads up to 2,000 lbs (10 kN). Unlike standard machine screw jacks, ball screw versions use rolling-element bearings between the screw and nut, which reduces input torque requirements by up to two-thirds and allows for higher duty cycles. Because ball screws are highly efficient, they are not self-locking. A brake motor or external locking device is required to hold the load in position.

A 1ton (2,000 lbs) worm gear ball screw jack is a high-efficiency linear actuator designed for high frequency use (NOT continuous use), high speeds, and precise positioning. Unlike standard machine screw jacks, these utilize recirculating ball bearings to minimize friction, which significantly reduces the input torque required—often by up to two-thirds. Ball screw, rolled thread, diameter 20 mm,  lead 5 mm, 10 mm or 20 mm. The most common standard worm gear ratios are 5:1 (high speed) and 20:1 (low speed). Ball screw can be customized in length and cut for free. Ball screw jacks are not self-locking at any standard gear ratio because of their high efficiency and low internal friction. A brake motor or external locking mechanism is always required to prevent the load from backdriving the jack when power is removed.
