Rubber elements for maximum flexibility
Everllence (former MAN Energy Solutions) engines with CENTA flexible couplings are strong partners for your vessel operation. Available in a variety of materials and configurations, CENTA couplings accommodate many different applications and industries, whose varying conditions affect its elements during operation. Size, geometry, and material characteristics are some of the relevant parameters for the transmission of the torque.

Everllence PrimeServ is a global authorized service provider for the CENTA product line, enhancing the competencies of the entire Everllence PrimeServ service network as well as improving the service level toward our customers.
A flexible coupling is a mechanical element composed of rubber elements. It is installed on a four-stroke engine and connects two shafts to transmit torque while allowing for some degree of misalignment and angular movement. A flexible coupling also reduces the stress and wear on the shafts and other components in the system by dampening vibration.
Service intervals of CENTA flexible coupling
Rubber is a natural material that hardens over time and loses its flexibility. For that reason, the original equipment manufacturer (OEM) recommends carrying out an annual inspection of the condition of the rubber according to the following intervals:
- After 1,000 operating hours
- After 4,000 operating hours
- Thereafter every 6,000 operating hours or annually (whichever is earlier)
The periodical inspection of the couplings, according to manufacturers’ recommendations as stated above, is required by the relevant classification societies. The rubber segment of the coupling should be replaced after 10 years or 50,000 running hours.
Benefits of servicing flexible couplings
There are several risks associated with delayed servicing of CENTA couplings:
- Exposure of the drive train and all connected system components to stresses beyond their limits
- Premature wear and tear on components in the drive train
- Failure of the bearings in driving and driven parts
- In case of failure, the lead time for the rubber component replacement can be more than eight weeks
