Centaflex A Size 30 – Compact Coupling for Small-Scale Power Transmission
The CENTAFLEX A Size 30 is a torsionally soft, elastic coupling ideal for small- to medium-scale drives requiring precise alignment and vibration damping. With a nominal torque capacity of 0.5 kNm, this size bridges the gap between microdrives and industrial-grade equipment—offering engineers a reliable and compact solution for light-duty mechanical power transmission.
⚙️ Key Technical Highlights
- Nominal Torque (TKN): 0.5 kNm
- Maximum Torque (TKmax): 1.4 kNm
- Continuous Vibratory Torque (TKW): 0.2 kNm
- Speed Range: up to 4000 rpm
- Temperature Range: –45 °C to +80 °C (natural rubber)
- Available in: Type 0 and Type 0–S
- Shore Hardness Options: 50 and 60
- ATEX Certified: Yes
🛠️ Common Applications:
- Compact diesel engines
- Agricultural machinery
- Pump and compressor units
- Gensets and PTO systems
- Automation and control assemblies
- Marine auxiliary systems
Thanks to its small footprint and resilient damping properties, Centaflex A Size 30 is a favored choice in machines where torsional vibration and space limitations must be addressed simultaneously.
Mounting Types
| Type | Description |
|---|---|
| Type 0 | Standard axial-radial bolted fit |
| Type 0–S | Enhanced with axial float (pins + bolts) for easier servicing and slight axial movement |
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
If your coupling element is marked with D.B.P. – 2019608 or JAP.Pat. – 778322, please note that these are patent numbers—not product codes. They indicate that your element is an original CENTAFLEX A design covered by international patents. However, they do not provide information about the size, type, or hardness.
To correctly identify your element, please check for additional markings or contact our team with:
- The element size (e.g. CF-A-030)
- The type (e.g. Type 0 or 0–S)
- The Shore hardness (usually 50 or 60)
- A photo of the existing element or machine label
