Centaflex 250AS coupling CF-A-250-0-S-50 is a torsionally soft OEM elastic coupling element produced by CENTA Germany for wind turbine, marine, and industrial power units.
Its Type 0-S (pin connection) design allows controlled axial float for easier installation and maintenance, protecting shafts and bearings from thermal expansion.
The 50 Shore natural rubber compound provides superior vibration isolation and alignment flexibility for systems operating under continuous dynamic load.

Fitment Type
Type 0-S (Pin Connection) – CENTA’s axial-float mounting design allowing minor axial movement, simplifying maintenance and reducing bearing load in dynamic drivetrains.
OEM Manufacturing Quality
Every CF-A-250-0-S-50 element is produced in Germany under CENTA’s ISO-certified standards with strict quality control. OEM elements ensure:
• Correct torsional stiffness and TVA-verified damping characteristics
• Dimensional precision and perfect OEM fit
• Stable performance and long service life under continuous duty
• Correct torsional stiffness and TVA-verified damping characteristics
• Dimensional precision and perfect OEM fit
• Stable performance and long service life under continuous duty
Why Choose Original CENTA Couplings
Imitation couplings often deviate in hardness and torsional stiffness, leading to resonance and vibration. Genuine CENTA Germany elements guarantee OEM-calibrated behavior, proven through dynamic TVA testing.
Using replicas risks mechanical imbalance, shortened service life, and drivetrain failure.
