Bearing diagnosis
2. Short signal path
The signal path between the bearing and the measurement
point must be as short and straight as possible. Shock
pulses lose strength over a long signal path (especially
when it has a large cross section) and are dampened when
deflected by bends in the path.
3. Loaded region
Shock pulses are generated mainly in the rolling interface,
where the load carrying element touches the raceway.
Therefore, the measurement must be located in the loaded
region of the bearing housing (as defined by the bearing's
emission window). Ideally, the measurement point should
be in line with the load direction.
Measurement is possible
only in the area defined by
the dotted lines.
