Centaflex A Size 400 – Heavy-Duty Coupling for High-Torque Industrial, Marine, and Power Applications

The Centaflex A Size 400 is a large, torsionally soft elastic coupling designed for high-torque, high-load drive systems. Built for extreme operating conditions, this coupling size is typically used in heavy industrial, marine, and energy sector applications where equipment must run reliably under continuous load.

With a nominal torque rating of 5.0 kNm and a maximum of 12.5 kNm, CF-A-400 is one of the largest and most powerful elements in the CENTAFLEX A range—engineered for systems where failure is not an option.

🛠️ Where Is Centaflex A Size 400 Used?

While less frequently ordered than mid-range sizes, Size 400 elements are installed in:

• Large generator sets (diesel or gas-powered)
• Industrial engine test benches
• Offshore energy systems
• Marine propulsion auxiliaries or hybrid shaft lines
• Power plant mechanical drives
• Large compressors or pumping stations

⚙️ These elements are typically chosen where high continuous torque, misalignment tolerance, and vibration isolation are essential, especially in rotating systems with critical uptime requirements.

⚠️ Match the Original Shore – Avoid Costly Failure

Large couplings like Size 400 are selected using TVA (Torsional Vibration Analysis) and stiffness models during OEM design. Replacing with the wrong Shore A hardness or a replica element risks:

• Unexpected resonance
• Rapid degradation
• Overload on shafts or bearings
• Unscheduled downtime

📌 Always replace with the original Shore hardness (typically 50 or 60). Read more: 🔗 Understanding Shore Hardness in Centaflex A Couplings

🔍 Genuine CENTA Means: Performance, Traceability, Safety

• Marked with Centaflex branding
• Include production date + patent numbers
• May be coated or packed in UV-resistant bags
• Designed with OEM torque specs

🛑 Copies may look similar but often lack proper Shore rating, dynamic testing, or heat resistance.
