A keyed for traveling nut jack (sometimes referred to as a rotating screw jack) features a lifting screw keyed to the worm gear as a single unit, forcing the lifting screw to rotate, but not translate. A flanged traveling nut, attached to the load, is driven by the rotation of the lifting screw. This type of jack is ideal for applications that cannot accommodate a screw protection tube or require a flush mount. Refer to the keyed for traveling nut dimensional drawing for each jack model. You can view a keyed for traveling nut jack in the Engineering Overview – Jack Designs on the Jack Designs page.
