The image is the ENVELOPE SPECTRUM of a rolling-element bearing's vibration signal, with the characteristic fault frequencies (BPFO outer / BPFI inner / BSF ball / FTF cage) marked; the computed features are in the metadata. Classify the bearing condition as one of: normal, inner_race, outer_race, ball.
