Abstract: Rolling contact bearing defects are analyzed in this paper experimentally. RCB plays a major role in rotating parts under high speeds and loads and are widely used in many machinery components. The defect or malfunctioning in this rolling elements leads to severe consequences in productivity and also costly downtime. So if we could monitor these rolling elements and could predict the severity of defect prior to they actually happen much advantage could be gain than after failure of rolling elements. Therefore vibration monitoring was used to detect various defects. This paper also shows compatibility of Vibration analysis technique for detecting the distributed defects in rolling elements. Experimental analysis is done on roller bearing with different load condition (1kg ,2kg,3kg) and without load condition with respective to speed of shaft in rpm (1000,2000,3000) . Then the comparison is carried out between healthy and defective bearings on the basis of results obtained from FFT analysis. The results extracted from experiments are presented and explained in detail.
