Screw Torque: Torque required to resist screw rotation (Translating Design Jacks) and traveling nut rotation (Keyed for Traveling Nut Design Jack). Lead: The distance traveled axially in one rotation of the lifting screw. Pitch: The distance from a point on a screw thread to a corresponding point on the next thread measured axially.

Jacton self locking gear jack incorporates an alloy steel or stainless steel worm shaft which drives a high strength bronze worm gear. The worm shaft is rotated by hand crank with handle, or by a electric motor. Then the worm shaft drives worm gear causes the acme thread lifting screw to translate or rotate,...

Speed of travel - gear ratio L (low speed) Worm gear screw jacks with trapezoidal screw pro-duce an advance of 0.25 mm for each full revolution of the worm shaft. That is, the linear speed is 375 mm per min at 1500 RPM. Worm gear screw jacks with ball screws achieve between 312 mm per min and 535 mm per min, depending on size and lead.

100 kN Cubic Screw Jacks main components with international standard materials: The main components are trapezoidal lifting screw (worm screw) with No.45 steel material, worm gear or travelling nut with bronze material, worm shaft with heat treatment No.45 steel material, thrust bearings, grease seals and gear housing with ductile iron.

Translating screw Jacks are most often selected. The main components of screw jacks are gear housing, trapezoidal lifting screw, worm screw and worm gear. Worm screw is rotated manually or by motor, then the worm gear will be rotated by the worm screw and the lifting screw moves through the rotating worm gear.
