CENTAMAX 18000 CAT Design Coupling – OEM NR with Unique CAT Bolt Pattern
The CENTAMAX 18000 CAT Design is a torsionally flexible OEM coupling element developed by CENTA Germany specifically for Caterpillar® 3512 and 3516 engines. While it shares the same proven elastic performance and torque range as the standard CENTAMAX 18000, this version incorporates a unique CAT-specific bolt pattern, making it the correct fitment for many CAT generator sets and propulsion engines.
🔧 Key Features of the CAT Design
- Exclusive Bolt Pattern – Engineered for CAT 3512 / 3516 flywheel configurations. This pattern differs from the standard SC and SCE layouts, ensuring precise fitment without modification.
- Extreme Torque Handling – Nominal torque capacity ~22,000 Nm and peaks up to 40,000 Nm, suitable for the largest diesel and gas engine drives.
- Natural Rubber (NR) Elastomer – Usually in Shore 72 for TVA-calculated stiffness.
- Temperature Range – Reliable from –45 °C to +80 °C.
- SAE J620 Standards – Typically for SAE 24 flywheels used in CAT heavy-duty engines.
- OEM Original Only – Manufactured in Germany by CENTA with full traceability.
Applications of CAT Design CENTAMAX 18000
- CAT 3512 / 3516 Marine Generators – Proven in auxiliary and propulsion gensets aboard offshore platforms and commercial vessels.
- CAT Gas & Diesel Power Units – Ensures vibration-free operation in high-output generator systems.
- CAT Rail and Industrial Drives – Trusted for traction and auxiliary power where reliability is mission-critical.
- Heavy Equipment – Provides secure torque transfer in mining, drilling rigs, and continuous-duty CAT-powered machinery.
Why Choose the CAT Design?
Unlike standard SC or SCE fitments, the CAT Design CENTAMAX 18000 guarantees:
- Exact bolt compatibility with CAT 3512 and 3516 flywheels.
- OEM reliability engineered in cooperation with Caterpillar®.
- Protection against downtime – no retrofitting, no mismatched parts, no resonance issues.
