Q: What is rotating screw jack?
A: A lifting screw keyed to the worm gear as a single unit, forcing the lifting screw to rotate, but not translate. A traveling nut, attached to the load, is driven by the rotation of the lifting screw. This type jack is ideal for applications that can not accommodate a screw protection tube and save enough mounting space.
