Damage to the roller bearings
If storage conditions are inappropriate there is a risk of bearing seizure damage. This can
result in material damage, such as damage to bearings caused by vibration.
On machines that have been supplied with a rotor shipping brace, secure the rotor as per the
notes on transportation (Page 32). Protect the machine against strong radial vibrations, since
the rotor shipping brace might not absorb these completely.

If the customer has already mounted parts, for example coupling, belt pulley, etc., the bearing
can be damaged during transport.
In this case, make sure that the customer uses a rotor locking device.
