SCREW JACKS introduction NIASA N/W/R Series screw jacks are a combination of a screw with a gearbox. There are three types of configurations that can be adapted to different requirements: …… N: The screw moves when the gearbox input shaft (worm shaft end) is activated. It includes a rounded screw protection tube on the back. …… W: The screw engages, as in configuration N but with the difference that the back protective tube is square section, which means it can be an anti-rotating screw. …… R: The screw does not move with the driving of the worm shaft, it only turns; it is the corresponding...
