• All dimensions are in millimeters.

• Dung sai
      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
