the Dana design guide lists normal and premium linear tolerances by component dimension. The first twelve rows use millimetres; the final row uses percentages.
Linear tolerance (mm)
| Dimension (mm) | Normal | Premium |
|---|---|---|
| 0–10 | ±0.12 | ±0.1 |
| 10–15 | ±0.2 | ±0.13 |
| 15–20 | ±0.25 | ±0.15 |
| 20–30 | ±0.3 | ±0.2 |
| 30–50 | ±0.4 | ±0.25 |
| 50–75 | ±0.5 | ±0.35 |
| 75–100 | ±0.65 | ±0.45 |
| 100–125 | ±0.8 | ±0.6 |
| 125–150 | ±1 | ±0.7 |
| 150–175 | ±1.2 | ±0.8 |
| 175–200 | ±1.5 | ±0.9 |
| 200–250 | ±1.8 | ±1.1 |
| >250 | ±0.8% | ±0.5% |
Design notes
- Dimension ranges reproduce the chart; the guide does not define how shared range boundaries are assigned.
- The >250 row is expressed as a percentage, not as an absolute millimetre tolerance.
- Confirm the required tolerances on the approved component drawing.
