Table 2: Interference allowance and tolerance on d2
| Outside diameter, d2 | Interference allowance1) | Tolerance on d22) |
|---|---|---|
| Up to 50 | +0.3 +0.15 | 0.25 |
| Over 50 up to 80 | +0.35 +0.2 | 0.35 |
| Over 80 up to 120 | +0.35 +0.2 | 0.5 |
| Over 120 up to 180 | +0.45 +0.25 | 0.65 |
| Over 180 up to 300 | +0.45 +0.25 | 0.8 |
| Over 300 up to 500 | +0.55 +0.3 | 1.0 |
| 1) The average value for d2 taken from a number of measurements shall not be greater than the value specified for d2 plus the interference allowance. For seals having grooved outside surfaces, additional interference allowances are to be agreed upon.
2) The tolerance on d2 (i.e. d2 max– d2 min) is to be determined by taking three or more measurements equallyspaced around the circumference. |
