Figure 8. Vibration analysis FFT representation of the raw signal. The reason there is no big amplitude at 1x BPFO of the raw acceleration signal can be explained as follows. When a ball hits the crack in the outer race, the actual vibration that occurs due to the hit has a much higher frequency than the BPFO.
