6.6 Measuring the temperature of the anti-friction bearing
1. The temperature of the bearing may only be measured during standstill.
2. Insert the temperature measuring probe [2] through the condensation drain hole [1]
directly after the variable speed gear unit has stopped.
• Depending on the type of variable speed gear unit, the condensation drain hole
has the following diameter:
3. Measure the bearing temperature at test points T1 and T2. If the bearing temperature
exceeds 100 °C (212 °F) at one of the test points, the respective anti-friction bearing
must be replaced.
To ensure safe working conditions and explosion protection, it is necessary that
the temperature of the anti-friction bearing does not exceed 100 °C (212 °F) at test
points T1 and T2 (see following figure).
If the temperature exceeds 100 °C (212 °F), replace the affected anti-friction
bearing.
The temperature of the anti-friction bearing can be measured with commercially
available temperature measuring probes. Important: Only use temperature mea-
suring probes with a maximum diameter of 4 mm (condensation drain hole).
