Centaflex A coupling - Size 400A/400AS – Heavy-Duty Coupling for High-Torque Industrial, Marine, and Power Applications| 2019608 | 778328
The CENTAFLEX A coupling Size 400 (also referred to as 400A coupling or 400AS coupling) is a large, torsionally soft elastic element developed by CENTA for high-torque, high-load powertrains.
With a nominal torque of 5.0 kNm and peak torque up to 12.5 kNm, the CF-A-400 delivers exceptional vibration damping, misalignment tolerance, and reliability for continuous-duty installations where downtime is unacceptable.
Designed for heavy industrial, marine, and energy-sector applications, the Size 400A / 400AS represents the upper end of the CENTAFLEX A series—combining proven German engineering with long-term operational safety.
Where the CENTAFLEX A coupling Size 400 Is Used
While less common than smaller models, CF-A-400 elements are integral to systems requiring high continuous torque and mechanical stability, including:
- Large diesel / gas generator sets
- Industrial engine test benches
- Offshore energy and hybrid propulsion systems
- Marine auxiliaries and shaft line drives
- Power-plant mechanical drives
- Large compressors and pumping stations
These couplings provide precise torsional damping and misalignment compensation—critical for heavy rotating machinery where uptime and balance are paramount.

Match the Original Shore – Avoid Costly Failure
Large couplings like the CENTAFLEX A size 400 are specified through Torsional Vibration Analysis (TVA) during OEM system design.
Installing an element with the wrong Shore A hardness or a non-original compound can lead to:
- Unwanted resonance and vibration
- Accelerated wear of shafts or bearings
- Unexpected downtime and repair costs
Always replace using the exact Shore value (50 or 60) specified by the equipment manufacturer to preserve the driveline’s designed torsional stiffness.

Genuine CENTA Means Performance and Traceability
Authentic CENTAFLEX A couplings include:
- Molded CENTAFLEX branding and part number
- Production date and international patents (D.B.P. 2019608 / JAP.Pat. 778322)
- OEM-validated rubber compounds for heat and load stability
- Optional protective UV-resistant packaging
⚠️ Replicas may mimic appearance but often lack verified Shore ratings, proper dynamic testing, or long-term heat resistance—posing serious mechanical risk in high-torque systems. More: Centaflex Original vs. Copies – What to Look For and Why It Matters
