Centaflex 250A coupling CF-A-250-0-50 is a torsionally soft OEM elastic element developed by CENTA Germany for wind turbine drivelines, generator units, and large industrial machinery.
Its Type 0 (bolt connection) provides a robust, secure mounting, while the 50 Shore rubber compound ensures smooth torque transfer, vibration damping, and excellent misalignment tolerance.

OEM Manufacturing Quality
Produced in Germany under CENTA’s ISO-certified standards, the CF-A-250-0-50 coupling guarantees:
• Accurate torsional stiffness and TVA-calibrated damping curve
• Consistent dimensional tolerances
• Long service life even under continuous load

• Long service life even under continuous load
Why Choose Original CENTA Elements
Aftermarket replicas often differ in rubber hardness and torsional behavior, leading to misalignment stress and vibration. Genuine CENTA elements deliver the exact stiffness and damping values defined by the OEM’s torsional vibration analysis.
Non-original copies can cause:
• Resonance and vibration issues
• Accelerated wear or shaft damage
• Unexpected downtime or mechanical failure
