製品説明

Worm Gear Screw Jack Description:

Screw jacks are a combination of a screw with a gearbox. There are three types of configurations that can be adapted to different requirements:

1. Translating screw design: The screw moves when the gearbox input shaft (worm shaft end) is activated. It includes a rounded screw protection tube on the back.

2. Anti-rotating keyed screw design: The screw engages, as in configuration translating screw design but with the difference that the screw with milled keyway or the back protective tube is square section.

3. Rotating screw design: The screw does not move with the driving of the worm shaft, it only turns; it is the corresponding travel nut that moves along the screw.
