Trapezoidal Axially translating screw (plain/keyed version)

     Driven by precision worm gearing (worm shaft and internally threaded worm wheel), the rotary motion is converted into axial linear motion of the screw, which travels/translates through the gearbox housing. The load is attached to the end of the screw. The cubic design allows for the upright or inverted orientation without special modification in the following 2 versions:

Plain: Suitable where the load is permanently attached to the jack, which will prevent the screw from turning.

Keyed: This is an anti-rotation version, suitable where the jack must move through free space before connecting with the load. In trapezoidal screw jacks, a milled slot in the screw is fitted with a key to prevent the screw from turning in free space. In ball screw jacks, a square guide is fitted to the end of the screw and runs within a square bottom pipe.
