The simulation of rolling contact fatigue strength of traction drive elements was proposed. It can consider the effect of size and distribution of inclusions in the material and the traction force generates on the contact surface. The estimation formula of rolling contact fatigue strength which evaluates the shear stress was obtained by the experiment. The maximum size of inclusions which affect the fatigue strength was estimated by the observation of material and the statics of extremes. As the result of simulation, 820 MPa of average rolling contact fatigue strength was estimated. The error was 4% in the experimental result of 790 MPa.
