Page: 32 / 126

Covers or tarpaulins used to protect the equipment against the weather must not come into
contact with the surfaces of the equipment. Use wooden spacer elements to ensure that air can
circulate freely around the equipment.
Storing indoors
The storage rooms must provide protection against extreme weather conditions. They must be
dry, free from dust, frost and vibration and well ventilated.
Bare metal surfaces
For transport, the bare surfaces (shaft ends, flange surfaces, centering edges) should be coated
with an anti-corrosion agent which will last for a limited amount of time (<6 months). Apply
suitable anti-corrosion measures for longer storage times.
Condensation drain hole
Open any condensation drain holes to drain the condensation depending on the environmental
conditions, every six months at the latest.
Storage temperature
Permissible temperature range: -20 °C to +50 °C
Maximum permissible air humidity: 60%
For machines that have a special design regarding the ambient temperature in the operating
state or the installation altitude, other conditions could apply regarding the storage
temperature. In this case, refer to the machine rating plate for data on the ambient temperature
and installation altitude.
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.
