摘要：Bearing is an indispensible element of almost any rotating machinery. These bearings in due course oftime undergo damage which may be confined to inner race, outer race, ball, cage, or all of these. Using various state ofthe art technologies like Vibration Analysis, Shock Pulse Method, and Acoustic Emission, these bearing faults can beidentified, without dismantling the machine. Among all these vibrational analysis of bearing signature is a classicaltechnique. This study differs from the others due to the load carried by the bearing. In practice, the load applied is withsome eccentricity and produces unbalanced force on bearing. The vibration response from ball bearing due to thechange in mass, eccentricity for loading and with varying speed is found experimentally by using FFT analyser. Thispaper presents an experimental study of bearing vibration and application of FFT spectra as a smart tool for diagnosisand identification of bearing faults like inner race defect, outer race defect and ball defect.
