Yes, FFT will show bearing frequencies, if there is a defect with the bearing. Enveloping/shock pulse/demodulation are terms used for early detection of impacting/repetitive events. Bearing fault should also show up in velocity FFT and time waveform in g's

another question, in which stage we can decide if the bearing change is required or no rely on vibration data?
