Abstract ud ud udROLLING BEARING FAULT DETECTION udON CENTRIFUGAL PUMP udUSING VIBRATION SIGNAL ANALYSIS ud udThe objective of this research is to obtain the vibration signal characteristic udgenerate from centrifugal pump, wich has defects on its bearing. The testing is udperformed on free load condition, centrifugal pump within rollig bearing inside, udand assumed that defects occurs in the bearing’s element only. Spectrum analysis udapplied to compare the vibration signal characteristic between good bearing and udfault bearing. udThe results show, first bearing fault indication that high amplitudo seen by udplotting wide range frequency. Furthermore, bearing within defect on its outer udrace generates dominant amplitude in 3xBPFO (197.5 Hz) frequency range, inner udrace fault generates dominant amplitude in 4xBPFI (435 Hz) frequency range. udWhile ball defect generates dominant amplitude in 2xBSF (62.5 Hz) frequency udrange. Good bearing has 0.802 volt amplitude, while inner race fault has 1.294 udvolt amplitude, outer race fault has 1.662 volt amplitude and ball defect has 2.006 udvolt ampitude
