3.4.7.
It is highly recommended to implement a vibratory control in accordance with the ISO 10816 standard to detect
any sign of mechanical evolution before breakdown.
Vibration and bearings temperature control
Accelerometers must be located closed to the bearings
Moreover, it is highly recommended to monitor the bearings temperature. This control can detect temperature
evolutions that are the first signs of the bearings end life. We recommend the process below:
- record initial bearing temperature after 1 hour of running.
- calculate the temperature rise = bearing temperature – ambient temperature.
- if temperature rise increase by 15°C during the machine life, the motor must be stopped.
