General notes
(a) All dimensions are in millimeters.
(b) Tolerances:

 

  • P = average pitch diameter of ring ±0.18
  • A = width of ring ±0.20
  • B & H = height of ring +1.3. -0.5
    Variation in height throughout the entire circumference of any given ring shall not exceed 0.5 within these tolerances
  • C = width of flat on octagonal ring ±0.20
  • R1 = radius in ring ±0.5
  • 23 deg = angle ±0 deg 30 min
  • R-30 = for lapped joint only
