- Q: Can the lifting screw be keyed to prevent rotation?
Posted Date: 2014/07/26 - Q: What is rotating screw jack?
A: A lofting screw keyed to the worm gear as a single unit, forcing the lifting screw to rotate, but not translate. A travelling 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.

A: Some loads don’t prevent lifting screw rotation. These applications require a keyed screw jack. A key, fixed to the jack housing and inserted in a keyway milled into the lifting screw, forces the lifting screw to translate without rotating.
