CENTAMAX 4000 Coupling | CENTA CM-4000-SC | Trusted OEM Coupling for Marine Gensets and Industrial Drives
The CENTAMAX 4000 NR Type SC is a high-performance torsionally soft coupling element, designed for diesel engines in marine generators, industrial drives, and construction machinery. Engineered with premium natural rubber (NR), it delivers stable torque transfer, vibration damping, and misalignment compensation, protecting engines and driven equipment from harmful torsional loads.
This size is especially common in diesel gensets installed on smaller vessels, where space is limited but reliability is non-negotiable. Compact, durable, and proven worldwide — the CM-4000 SC is the go-to choice for operators who value uptime and performance.
At AWELASTIC, we don’t just sell couplings — we supply confidence. Every CENTAMAX 4000 SC element we offer is new, original, and in stock, backed by our expertise and trusted by customers across marine, powergen, and heavy industries.
