3.2.2 Storage
Note
Replacing roller bearings
•
Even if the motor was stored for more than three years under favorable conditions (i.e. in
a dry, dust-free room that is not susceptible to vibration), you must replace the bearings.
• If the motor was stored under unfavorable conditions, you must replace the bearings after
approx. 18 months.
NOTICE
Seizure damage to bearings
If the motors are stored incorrectly, bearing seizure damage can occur (e.g. brinelling) as a
result of vibrations.
• Observe the instructions for putting into storage.
The motors can be stored for up to two years in a dry, dust-free room that is not susceptible
to vibration (v
eff
< 0.2 mm/s) without the specified storage time being reduced.
