CENTAMAX Couplings for Marine, Powergen & Heavy Equipment – Original. In Stock. Ready to Ship

Original CENTA CENTAMAX Coupling Elements – Sizes 400 to 18000

The CENTAMAX coupling is a highly elastic CENTA coupling engineered for maximum durability, efficiency and reliability in marine, railway, power generation and industrial drives. Developed in close collaboration with engine and equipment manufacturers, including Wärtsilä and CAT, CENTAMAX ensures seamless integration and performance excellence. At AWELASTIC we supply original OEM CENTAMAX elements in all common sizes and fitment types: SB, SBE, SC, SCE, silicone and CENTAMAX-G.

CENTAMAX fitment types

• Type SB – the standard flange-mounted version, widely used in diesel generators, marine auxiliaries and industrial drives.
• Type SBE – a variation of the SB design with a different mounting arrangement, specified in certain generator and industrial applications.
• Type SC – the most common solution for larger CENTAMAX elements: bolts pass through the plain (unthreaded) holes of the element and tighten into the hub.
• Type SCE – for large and heavy-duty sizes: the element has threaded holes, so bolts screw directly into the element.
• CENTAMAX-G – supplied with SAE flywheel adapters.

Key features and benefits

• Superior durability: designed with high-quality materials, CENTAMAX couplings withstand extreme conditions and provide long-lasting performance.
• Optimized efficiency: high torsional flexibility reduces vibrations for smooth and efficient power transmission.
• High-quality engineering: manufactured to original OEM standards for reliability in critical applications.
• Advanced ventilation: the HTC (High Thermal Capacity) design allows superior power loss dissipation, making it possible to use smaller, cost-effective coupling sizes.
• Fail-safe design: available with an optional fail-safe device, preventing system failures in case of overload.
• Wide temperature range: from -45°C to +120°C, depending on material selection (NR, Si or CENTALAN HT).
• Versatile applications: marine propulsion couplings, shaft couplings and power transmission in industrial and marine settings.

Designed for excellence

CENTAMAX couplings provide resonance-free operation, shifting critical vibrations below operational speed and reducing stress on connected components. The product line includes CENTAMAX-S, CENTAMAX-G, CENTAMAX-HTC and CENTAMAX-B, each tailored for specific applications.

Trusted by industry leaders

As a preferred choice for marine coupling solutions, CENTAMAX is trusted by engine producers like Wärtsilä and CAT, ensuring compatibility and superior performance in demanding environments.

Frequently asked questions

Are these original CENTA CENTAMAX elements?

Yes. AWELASTIC supplies original OEM CENTAMAX coupling elements manufactured by CENTA, not aftermarket copies.

What is the difference between CENTAMAX SC and SCE?

SC elements have plain, unthreaded holes – the bolts pass through the element and tighten into the hub. SCE elements have threaded holes, so the bolts screw directly into the element. In some sizes (e.g. CENTAMAX 8000 SCE) both plain and threaded holes are present; in the largest sizes (e.g. CENTAMAX 18000 SCE) all holes are threaded.

How do I identify the correct CENTAMAX size and type?

Check the markings on your existing element and compare it with our CENTAMAX coupling identification guide. Dimensions, performance data and selection information are in the CENTAMAX catalogue and downloads. If you are not sure, send us a photo of the element and its markings.

Which material should I choose – NR, silicone or CENTALAN HT?

The material determines the permissible temperature range (overall from -45°C to +120°C, depending on material). Always choose the same material and shore hardness as specified for your drive, or contact us with your current element code.
