Can someone explain me how are the different frequency bands useful for detecting bearing faults using resonance demodulation?

This presentation has a pretty good overview of characterizing bearing faults. In essence, once the measured frequency content does not match what is considered a good response from a bearing, it can be flagged as faulty or nearing fault.
