Figure 7.2: Misalignment combination
The misalignment as a percentage is calculated as follows:
7.3. Hub bore specifcations
When boring, or reboring the hub, it must be ensured that:
- the hub is precisely aligned,
- the form and positional tolerances in accordance with DIN ISO 286 are adhered to (see
figure 7.3).
Life-threatening danger!
The max. permissible bore diameters specified in table 7.3 may not be ex-
ceeded. If the permissible values are exceeded, the hub could crack during op-
eration. This could cause life-threatening danger due to flying parts.
Attention!
Never clamp onto the sealing surface! The operator bears the sole responsibil-
ity for any damages that may occur due to defective rework on the unbored /
roughly bored coupling parts.
