Ball screw jacks MA and SJ series (screw jacks)

Ball screws exceed the application limits of traditional Acme screw jacks. High linear speeds, the ability to withstand a continuous duty cycle, no wear at the nut, zero axial play, an exact estimation of the expected service life, half the energy consumption and half the installed power.

Servomech jacks are suitable for push or pull loads, in various mounting positions (vertically up/down or horizontally).

Servomech ball screw jacks are ideal for industrial and automation applications in general and are used in a wide range of sectors such as heavy mechanical applications, steel mills, sheet metal production and processing, the manufacture of tube and pipe, metal wire, marble, wood, stone, glass processing machines, printing and processing machines, presses for the production of rubber and plastic, telecommunications, the marine sector and railways. They are also suitable for applications in the food and beverage industry.

Servomech ball screw jacks are the right product for all machine constructors looking for higher productivity, greater efficiency and better performance, while at the same time reducing costs and saving energy
