Rotary module – rotation angle of up to 6480 °

The new CRM rotary module is lighter and more compact than, for instance, static guide troughs. It allows a rotation angle of up to 6480 ° and requires minimal installation space. Various types of cable (power, signal, FOC, pneumatic, oils) can be guided. Rotary unions that are inflexible and susceptible to faults are eliminated, allowing a simple, ready-to-install unit.
Possible areas of application:
General machine and plant engineering, Production plants / Material Handling, Machine tools, Industrial robots, Medical technology, Wind power stations, Rides / Theme Park, Satellite-telescopes/antennas
