Designed by us, the Rotary Nut groups differ from all of the other groups in that they have a fixed trapezoidal screw and drive transmission directly to the rotating nut. This system of drive directly to the mobile part allows the use of various mobile units on the same screw with independent positioning of each carriage.
These Groups are composed of nitrided steel supports that used with a fixed trapzoidal screw, by means of the rotating nut with bearings, and assembled with drive transmission components like paired bevel gears, pinions, gear wheels etc. forming complete Manoeuvring Groups for fitting to adequately designed machinery. The Rotary Nut groups have some standard models with mobile patform driven by paired bevel gears (ratio 1:1 or 1:2) and other special models using a gearwheel or chain pinion drive.
Support for screw from TR 20 to TR 60.
