Storage time
Turn the shaft once every year to avoid bearing brinelling. Prolonged storage periods reduce the
useful life of the bearing grease (aging).
Open bearings
• For open bearings, e.g. 1Z, check the status of the grease when stored for longer than 12
months.
• Replace the grease if it is identified that the grease has lost its lubricating properties or is
polluted. The consistency of the grease will change if condensation is allowed to enter.
Closed bearings
• For closed bearings, replace the DE and NDE bearings after a storage time of 48 months.
NOTICE
Storage
The motor can be damaged if you use it or store it unprotected outdoors.
• Protect the motor against intensive solar radiation, rain, snow, ice and dust. Use a
superstructure or additional cover, for example.
• If required, contact the service center, or technically coordinate outdoors use.
4.5.4 Securing the rotor
Depending on the version, the machine is fitted with a rotor shipping brace. This protects the
bearings against damage due to shock and vibration during transport or storage.
NOTICE
Motor damage due to vibrations
Not using the rotor shipping brace can cause damage to the machine if it is jolted during
transport or storage. Material damage can result.
• If the machine is fitted with a rotor shipping brace, this should always be used when
transporting the machine. The rotor shipping brace must be attached during the transport.
• Protect the motor against strong radial shocks and vibration when storing, as the rotor
shipping brace cannot completely absorb these forces.
• Do not remove the rotor shipping brace until you are ready to push on the output element.
• If the customer already has mounted parts, such as a coupling or belt pulley, the bearings
can be damaged during transport. In this case, make sure that the customer uses a rotor
shipping brace.
• For machines with a vertical type of construction:
– Do not remove the rotor shipping brace until the machine is in a vertical position.
– If a machine has to be transported in a horizontal position, the rotor must be fixed in
position before the machine is turned onto its side. Vertical machines can be supplied in
the horizontal position from the manufacturing plant.
