CENTAMAX G

CENTAMAX-G Series Couplings – The OEM Standard for Generator Drives and Industrial Diesel Power Systems

Showing all 6 results

The CENTAMAX-G series is a high-performance family of torsionally soft flexible couplings engineered by CENTA Germany specifically for diesel-driven generator sets, marine auxiliary power units, and industrial rotating machinery.

Designed to solve the unique challenges of generator drives, the G-Series provides stable torsional behavior, efficient vibration damping, and precise torque transmission, even under fluctuating load conditions.
At the core of every CENTAMAX-G coupling is a proven mechanical concept combining a natural-rubber elastic element, an aluminum outer ring, and a highly reliable taper-lock connection system.
This makes the G-Series one of the most widely used OEM couplings in generator sets worldwide.

What Makes the CENTAMAX-G Series Special?

 
1. Torsionally Soft Architecture for Generator Systems
Generator drives operate within narrow torsional ranges. CENTA’s torsionally soft rubber element shifts critical resonances below idle speed, preventing harmful torsional peaks and electrical instability under varying loads.

 

2. High Damping, Stable Output
The natural rubber (NR) compound offers superior damping characteristics, absorbing engine irregularities and smoothing generator output — especially important in:
  • standby gensets
  • load-variable power plants
  • marine auxiliary generators
  • industrial backup systems
3. Taper-Lock Connection – Secure, Accurate, and Fast

One of the defining features of the CENTAMAX-G series is its taper-lock hub system.

Instead of conventional shrink-fit hubs or keyed shafts, the taper-lock system provides:

  • Quick installation without machining
  • Perfect concentricity for low vibration
  • High torque transfer capability
  • Easy removal or replacement during maintenance
  • Repeatable accuracy with every installation
Depending on size, G-Series couplings typically use:
  • 3535 taper bush (G-1800)
This design ensures a secure, slip-free mechanical connection that meets generator OEM standards.

 

4. SAE Flywheel Compatibility
CENTAMAX-G couplings are engineered to bolt directly onto standard SAE flywheels.
Available adapter plates include:
SAE 11.5 — SAE 14 — SAE 18
This makes the G-Series suitable for virtually every major engine manufacturer in gensets and industrial power.

 

5. High Thermal Stability
The G-Series design incorporates ventilated outer rings, helping maintain thermal balance in enclosed generator housings or marine engine rooms.
Improved airflow significantly increases the lifetime of the natural-rubber element.

 

6. Fully OEM-Defined Torsional Behavior
All CENTAMAX-G couplings are calibrated through Torsional Vibration Analysis (TVA) in cooperation with engine and generator manufacturers.
Only original CENTA elements guarantee:
  • correct torsional stiffness
  • proper resonance behavior
  • balanced damping curves
  • reliable long-term performance
Aftermarket copies do not replicate this behavior and often fail prematurely.

Where Are CENTAMAX-G Couplings Used?

The G-Series is installed in thousands of power systems worldwide, especially in:
  • Industrial diesel generator sets (stationary and mobile)
  • Marine auxiliary power units and emergency gensets
  • Offshore platform power modules
  • Industrial engines powering compressors, pumps, fans
  • Utility-scale generator installations
  • Military and civil emergency power equipment
Whenever safety, uptime, and vibration control are essential, the CENTAMAX-G is the preferred OEM solution.
