MCA-F (Metal C-Ring spring energized for axial pressure application)

To the overview
Metal C-Ring

Axial pressure application

  • The reference diameter for MCA-F type rings is the outside diameter.
  • Nominal cross-section CSR: Cross-sectional dimension similar to the cord thickness for elastomer O-rings.
  • Performance index: shows the wall thickness of the ring
  • Wall thickness Wt: Sheet thickness of the ring
  • 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
  • Groove width W min: axial design minimum dimension to ensure pressurization of the ring
  • Radius R: Design dimension that improves the support of the ring when pressurized.
  • Outer diameter of the groove OD: corresponding design dimension to the outer diameter of the ring
  • Inner diameter of the groove ID: corresponding design dimension to the outer diameter of the groove
