MAN is Authorized Service Provider for the CENTA coupling product line. CENTA coupling and MAN engine, two companies with long and rich histories in the marine and power market, are partnering to improve the value delivered to customers in the industry.   CENTA flexible coupling is a element composed of rubber. It is fixed on a four-stroke engine and connects engine to gearbox or alternator for transmit torque while allowing for some degree of misalignment and angular movement. CENTA rubber coupling additionally reduces the stress and wear on the engines and other components in the system by dampening vibration. Available in a variety of materials and configurations, CENTA couplings accommodate many different applications and industries. Size, geometry, and material characteristics are relevant for the transmission of the torque.

MAN services for CENTA coupling (carried out by expert MAN engineers):

-Yearly inspection of CENTA couplings product line -CENTA coupling element replacement services -Sell Original spare part kits for CENTA coupling -Service for alignment checks and engine installation

Best time to service CENTA flexible couplings by MAN energy solution

couplings rubber elements is a natural material that hardens over time and loses its flexibility. For this reason, carrying out an yearly inspection of the quality of the rubber is recommended by the OEM according to the following intervals: first time: after 1000 working hours second time: after 4000 working hours Thereafter every 6,000 operating hours or yearly (whichever is earlier)   The periodical inspection of the couplings, according to CENTA company recommendations as stated above, is required by the relevant classification societies. After 8 years or 45,000 working hours, it is recommended that the rubber element of the coupling is replaced.

Flexible couplings service importance

-In case of failure, the lead time for the rubber element delivery can be more than 10 weeks -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 engine or gearbox    

lifetime of CENTA Coupling

  Lifetime in normal operating conditions = 10 years / 50,000   Running hours if operating at medium speed (If operating is at speeds above 1.200 rpm) = 5 years /25,000 hours  

lifetime of CENTAMAX coupling

The theoretical lifetime in normal operating conditions is 5 years. In PTO (Power Take Off) applications, this lifetime will be reduced.  

lifetime of CENTALINK coupling

The theoretical lifetime in normal operating conditions is 10 years.  

Extend the life of the coupling rubber element:

Ensure favorable operating conditions by avoiding exposure to extreme temperature, ozone, UV, chemicals, shock, loads – torsional impacts, misalignments.
