Acc. to DIN 5480 the recommended tolerances and deviations for tip and root circle diameters is given in the table below.
| Flank centering | Diameter centering | ||
| External diameter centering | Internal diameter centering | ||
| Tip circle diameter of hub, da2 | H11 | H11 | H7 |
| Tip circle diameter of shaft, da1 | h11 | h6 | h11 |
| Deviation for the hub root circle diameter, df2 | Adf2 = (0.2 * m + 1.73 * (Ae + TG)) | H7 | H14 |
| Deviation for the shaft root circle diameter, df1 | Adf1 = - (0.2 * m + 1.73 * (-As + TG)) | h14 | h6 |
where, Ae = space width, As = tooth thickness, TG = Overall Tolerance
