Centaflex 4A coupling CF-A-004-0-50 is a torsionally soft OEM elastic element designed by CENTA Germany for miniature mechanical drives and compact automation systems that require extremely smooth torque transmission and alignment flexibility.
Its Type 0 (bolt connection) ensures rigid but compact assembly, while the 50 Shore natural-rubber compound offers outstanding damping capacity — protecting sensitive instruments and small motors from vibration and misalignment.
This model is commonly used in precision automation, measuring devices, and small hydraulic or pneumatic setups, offering long service life and low noise even under continuous operation.

Why Choose Original CENTA Couplings
Aftermarket imitations often fail to match the exact torsional and material properties required for precision systems, resulting in noise, resonance, or early fatigue.
Only genuine CENTA Germany couplings ensure OEM-calibrated performance verified through Torsional Vibration Analysis (TVA) and real-world endurance testing.
