CRM rotary module

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

Tech up  
Tech up

  • No slip ring: works with every kind of cable
    (electricity, data, air or fluids)
  • Can also be equipped with corrugated tubes
  • Small installation space, very low profile
  • Rotation angle up to 6,480° (depending on system)
  • Resistant to splashing water due to uninterrupted
    guide

Cost down  
Cost down

  • Cost-effective in case of repair (replacement of individual
    components possible)
  • Adaptable to technological development due to
    simple replacement of the used cable

Sustainability  
Sustainability

  • No additional copper components
    in the system (apart from copper in cable) Parts ate reusable
  • Less raw material required thanks to the option of partial repair  instead of complete replacement
  • Have your energy chains recycled as part of the igus "chainge recycling programme" at the end
    of its life cycle. Irrespective of their manufacturer. You receive a voucher: chainge programme
  • igus supports the circular economy of plastics and invests in chemical recycling

Test: clearance height  

Test: CRM rotary module and TB12 twisterband clearance height


In its test laboratory, which is the largest in the industry, igus compared the CRM rotary module and twisterband. The two series were evaluated with regard to their clearance height given the same rotation angle (6480°)
 
The results showed that, given the same rotation angle (6480 ), the CRM rotary module requires a lower clearance height that the twisterband. The rotary module's clearance height is approx. 99mm, while the TB12 twisterband's is approx. 260 mm.

Application example with rotary modules

Bridge bearing

The igus® 540° rotary module is used in the interior of the bridge bearing to realise pivoting movements.
