Effect of Slip in Performance of Rolling Element Bearings

Performance analysis of rolling element bearings is a complex phenomenon, which has been studied by researchers from many points of view. A variety of parameters such as operating torque, PV value, and slip rate plays role in performance of rolling element bearings. In conventional bearing design and analysis an assumption of “pure rolling” is made. This assumption is not rigorous especially in lightweight and high-speed bearings. This paper reviews the effect of slip in performance of rolling element bearings such as frictional loss, torque, heat generation, wear and rolling contact fatigue. The research work already done on the performance of bearings under slip and partial slip conditions has been studied and reviewed.
