The igus® 540° rotary module is used in the interior of the bridge bearing to realise pivoting movements.
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:
|Part No.||Cable diameter||Angle of rotation||Necessary rotary module cable length|
|CRM.250.08.01||5mm - 8mm||6480°||4,5m|
|CRM.250.11.01||8mm - 11mm||4320°||3,3m|
|CRM.250.15.01||11mm - 15mm||2160°||2,4m|
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.
