Abstract: Rolling element bearings (REB) find widespread domestic and industrial applications. Proper function of these appliances depends on the smooth and quiet running of the bearings. In industrial applications these bearings are considered as critical mechanical components and a defect in such a bearing, unless detected in time, causes malfunction and may even lead to catastrophic failure of the machinery.[1] Defects in bearings may arise during the manufacturing process as well as over using and weathering of the bearings. Therefore detection of these defects is important for condition monitoring as well as quality inspection of bearings. Different methods are used for detection and diagnosis of bearing defects; they are classified as vibration and acoustic measurements, temperature measurements and wear debris analysis. The purpose of this study is to monitor the condition and diagnosis of fault that may occur in rolling element bearing.[1]
