Inverted Rotating Features

Inverted Rotating Ball Screw Jacks - 1/4 Ton to 100 Ton

An inverted rotating ball screw jack has a lift shaft that moves a nut as it turns. The lift shaft is fixed to the worm gear. This causes the load, which is attached to the travel nut, to move along the lift shaft. An inverted rotating ball screw jack has the lift shaft extending out the bottom of the jack.

Depending on size, inverted rotating designs are available with optional accessories such as boots, motor mounts, right-angle reducers, motors, encoders and rotary limit switches.
