    The microscopic mechanisms for rolling contact fatigue and changes of microstructure during rolling contact are reviewed for rolling bearings.It is pointed out that the local microscopic plastic deformation and carbon diffusion are determinants for control of fatigue and structural change.The influences of operating condition and material heat treat-ment of bearings on rolling contact fatigue life are analyzed.
