Niasa Screw Jacks

We are able to distribute and supply an Niasa Screw Jacks in Delhi, India. 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 Series: The screw moves when the gearbox input shaft (worm shaft end) is activated. It includes a rounded screw protection tube on the back.
W Series: 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 series: The screw does not move with the driving of the worm shaft, it only turns; it is the corresponding nut that moves along the screw.
In applications that so require, there is a possibility to protect the screw with a bellow (available in different materials), to protect it in the outside environment and make the screw jacks suitable for outdoor operations or environments with a certain atmospheric aggressiveness.
Screw jacks are often the most optimal technical and economical solution for applications that require lineal, precise and safe movement, for transfer and for elevation, mainly for medium-heavy loads and medium-low speeds.

Their main advantages against other systems, such as pneumatic or hydraulic cylinders, are the following:
1. Greater movement and positioning precision.
2. Greater safety, due to their reversibility in many configurations (ask NIASA) and/or the incorporation of different braking devices.
