This study investigates the detectability of roller bearing damage by the frequency analysis of bearing vibrations. The magnitude characteristics of peaks in the vibration spectra are analysed. It is shown that the frequency information of vibration spectra for undamaged roller bearings can be the same as that for damaged ones. However, the magnitude information of vibration spectra for undamaged roller bearings is different from that for damaged ones. Thus, to detect the initial fault of roller bearing reliably, both the frequency information and magnitude information of vibration spectra have to be used.
