CENTAFLEX® - R

The CENTAFLEX-R is a simple robust ROLLER coupling with a progressive torsional characterisation. Ideal for boat drives, providing a very low stiffness at low torque (& speed) which shifts the torsional resonance below idle speed and prevents gearhammer (gear chatter).

And there are also numerous applications for this kind of coupling in many different industrial drives.

Using the rubber-in-compression principle with rubber rollers between cams, the coupling offers high reliability as it is free from a bonding process common in couplings of equal performance.

The associated cams are profiled using sophisticated computer design(CAD) backed by extensive physical testing.

Important features and advantages of the CENTAFLEX-series R.

Progressive torsional characteristic with very low stiffness at low torque and increased, but moderate stiffness at high torque
Simple, reliable, no bonding, only rubber in compression
Special developed, temperature resistant elastomer CENTALAN with high damping, suitable for high ambient temperature of more than 100°C (212°F)
For commercial heavy duty or difficult applications we recommend the special "HD" rubber roller, which are also oilresistant.
Well proven in service and approved by classification societies.

High allowable energy loss by intensive inner and outer bentilation
Suitable for blind fitting in bell housings
Economic / easy maintainable design
Protected by international patents
Area of application : flange mounted units or well aligned independently mounted units on rigid mounts
The CF-R is part of the CENTA- Antriebe family of marine drive couplings covering a range between the more than 100 000 times proven CENTAFLEX-DS (Dual Stage) series and the well established, CENTAX series up to 500 kNm.


	CENTA Couplings for flange mounted gears This simple, robust roller coupling has a progressive characteristic, which is ideal for boat drives. Its extremely low stiffness at low torque shifts the resonance below idling speed and thereby avoids gear chatter. It is very reliable, with no rubber bonding, only compressed temperature resistant elastomeric rollers transmit the torque. The couplings are fail-safe and suitable for blind assembly. Torque range 0.25-15 kNm.
