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 |
