Performance Behaviors of Rolling Bearings and New Developments

Rolling bearings are broadly used in many industrial applications. The fatigue life failure of one of the elements of rolling bearing leads to loss of productivity in industries. The major causes of failure of rolling bearings are a rise in operating temperature, an increase in frictional torque, increased vibrations, centrifugal force effect in thrust bearings and lubrication starvation. All these factors lead to increased wear of balls and races. The literature survey reveals that the researchers studied the performance behaviors and characteristics of rolling elements of the bearing through analytical models and experiments. Many techniques (such as Envelop Analysis, Fourier Transform Analyzer, etc.) presented for continuous health monitoring of rolling bearings with/without modification in geometry and with the use of coated surfaces of the rolling elements. This paper presents a literature review about the analytical models and experimental methods for predicting fatigue life failure and a comprehensive study about the problems that occur and recent development in the rolling bearing.
