4.8 Radial eccentricity, concentricity and axial eccentricity

The shaft and 󹪞ange accuracies are always checked in accordance with DIN 42955, IEC 60072.

For shaft heights 180, 225 and 280, however, the 󹪞ange accuracy is checked in accordance with

DIN 50347. Data deviating from these values are indicated in the dimension drawings.
