Ball bearing life
The bearing service life of the motor-integrated ball bearings determined
in accordance with the standard calculation method is largely determined
by the grease service life F10h and is approx. 30,000 to 40,000 operating
hours in standard use, taking into account a temperature and load spec-
trum. The fan or motor is maintenance-free due to the use of ball bearings
with life-time lubrication. Once the grease service life F10h has been
reached, it may be necessary to change the bearing. The bearing service
life may change compared to the speci
fi
ed value if operating conditions
such as increased vibrations, increased shocks, increased or excessively
low temperatures, humidity, dirt in the ball bearing or unfavourable control
modes are present. A service life calculation for special applications can
be created on request.
