Disconneting at 100 °C
Temperature is a long-time indicator for the machine load.
Excessive bearing load results in an increase in temperature
of the bearing. Provided that the anti-friction bearing is used
properly in accordance with the advised design instructions,
a nearly constant working temperature of the bearing will
turn up at constant working conditions after the initial operation
phase. If the temperature changes without alteration of
the speed or the load or without addition or reduction of
warmth, this is an indication for a disturbed lubrication condition.
Load changes due to malfunction of the non-located
bearing can be recognised by the temperature course of the
bearing. Bearing damages due to interruptions of the lubrication
film or malfunction of the bearing can be recognized early
by using a temperature monitoring device for the bearing.
Running period damages due to fatigue and ageing can not
be detected by a temperature monitoring device for the bearing.
The bearing temperature is measured by an electric temperature
probe directly on the outer ring of the bearing.
