Shore Hardness: Why You Must Match the Original

Centaflex A couplings are not generic rubber parts. Each Shore hardness—50 or 60—has a very specific dynamic behavior, directly affecting torsional stiffness, resonance characteristics, and system lifespan.

Replacing a worn element with the wrong Shore hardness can lead to premature failure, noise, or torsional resonance.

Always match the original Shore value (usually marked on the coupling or machine documentation). These elements are often selected during OEM design together with TVA (Torsional Vibration Analysis) and machine-specific calculations.

📌 About D.B.P. – 2019608 and JAP.Pat. – 778322

Many original CENTAFLEX elements bear the markings D.B.P. – 2019608 or JAP.Pat. – 778322. These are international patent numbers, confirming that your element is an authentic CENTA product, but they do not indicate the size, type, or hardness.

To ensure a correct match, check:

  • Size and series code (e.g., CF-A-080)
  • Mounting type (0 or 0–S)
  • Shore hardness (usually 50 or 60)
  • Or send us a photo—we’ll identify it for you.
