Bearing is one of machine components which is used to support rotary shaft. Unbalance force and impropriate lubrication which occur on bearing will eventually cause local defect. This defect can be detected by measuring vibration signal which is generated by the bearing. Detecting local defect requires specific methods to process the vibration signal, such as: shock pulse and peakvue (stress wave propagation) methods. Research on comparing results between shock pulse, peakvue, and vibration methods has not been done so far. <br /> <br /> <br /> In this research, shock pulse, peakvue, and vibration measurements are done to detect local defect on ball and roller bearing, each of which consisting of normal bearing, and bearing with outer and inner race defects. Some parameters are varied in this research to assess the variation of shock pulse, peakvue, and vibration analysis. <br /> <br /> <br /> Based on the analysis of test results, it can be concluded that the shock pulse method is capable to identify defect on bearing and abnormal bearing operation. Similarly peakvue method can also identify some defects but cannot <br /> <br /> <br /> detect abnormal bearing operation, in contrast, vibration method was failed to detect the existence of faults and abnormal bearing operation.
