Upright Keyed Features

Upright Translating Keyed Ball Screw Jacks - 1/4 Ton to 75 Ton

Upright translating keyed ball screw jacks are supplied with a device that prevents rotation of the lift shaft. Anti-rotation is accomplished by a square guide attached to the screw translating inside a square stem cover attached to the jack. The square stem tube is supplied with lube fittings.

An upright translating keyed ball screw jack has a lifting shaft that moves through the gear box. The lift shaft extends out from the top of the worm screw jack. 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.

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