Bearing replacement interval
The bearings are subject to wear and must be replaced after a defined number of operating
hours.
For average load levels, the bearings must be replaced after approx. 25,000 hours.
Bearing replacement intervals can be extended if the motor is operated under favorable
conditions, e.g. low average speeds, low radial forces (cantilever forces), vibration load.
Note
Harsh operating conditions
If the motor is subject to harsh operating conditions (e.g. continuous operation at n
vibration/shock loads, frequent reversing duty etc.), the bearing replacement intervals t
can decrease by up to 50%.
