Rolling element bearing faults are among the main causes of breakdown in rotating machines. The influence of surface defects on contact behaviour is of great importance in many tribological situations. This paper presents the review of Vibration response of ball bearing with surface defect on the races of ball bearing. The effect of different types of defects affect the bearing performance but the most common type is the surface defects on the races which may cause sudden failure of machine and hence rated life reduces. Surface defects include surface roughness, waviness & misaligned races. These are caused due to manufacturing error & operating conditions. Bearing failures contribute major cause of machinery breakdown resulting in costly downtime. To prevent such failure bearing condition monitoring methods have been developed The study of vibration response due to surface defect is necessary for condition monitoring of rolling element bearing to improve bearing performance.
