Translating Screw Jack

A translating jack has a lifting shaft that moves through the gear box. A nut is integrated with the worm gear such that the worm gear and nut rotate together. When the lift shaft is held to prevent rotation, the lift shaft will move linearly through the gear box to move the load.

This printing press application (See Image Below), utilizes two upright translating ball screw jacks to set the proper gauge on the feed rollers.
