Abstract：This paper presents a comprehensive elaboration of research focus, methods and progress in the field of rolling contact fatigue of bearing steels. The paper firstly analyzes the distribution of Hertzian stress components inside material under rolling contact as well as material response to cyclic stress, revealing the root cause of fatigue happening at subsurface. Secondly, methods of fatigue testing on bearing steels are summarized, with their advantages and disadvantages analyzed. Thirdly, key factors that influence the rolling contact fatigue life of bearing steels are discussed. Finally, two main manifestations of subsurface-induced rolling contact fatigue of bearing steels, crack growth and microstructural decay, are systematically elucidated, where the vital fatigue mechanisms are introduced and key research directions in the future are proposed.
