MCA (Metal C-Ring for axial pressure application)
Axial pressure application
| CSR | Nominal cross-section CSR: Cross-sectional dimension similar to the cord thickness for elastomer O-rings. |
|---|---|
| Code | Performance index: shows the wall thickness of the ring |
| Wt | Wall thickness Wt: Sheet thickness of the ring |
| ODR | Outer diameter of the ring ODR: Diameter range in which the ring can be finished. The outside diameter of the ring is freely selectable in the specified range |
| W | Groove width W min: axial design minimum dimension to ensure pressurization of the ring |
| R | Radius R: Design dimension that improves the support of the ring when pressurized. |
| OD | Outer diameter of the groove OD: corresponding design dimension to the outer diameter of the ring |
| ID | Inner diameter of the groove ID: corresponding design dimension to the outer diameter of the groove |
