8.4 Replace bearings
The bearing service life depends greatly on the operating conditions and so cannot be
calculated reliably. In the operating conditions specified by the operator, bearing life can be
calculated and indicated on the rating plate. If no information is given, changes in vibration
and noise pattern can serve as an indicator that an immediate bearing replacement is
necessary.
