The rolling contact fatigue tests with specific sliding 0% and 20% measuring tangential force, the pulsating compression fatigue tests and the completely reversed torsion fatigue tests were carried out using six structural metals. The relationships of the fatigue limit among the rolling contact fatigue, the pulsating compression fatigue and the completely reversed torsion fatigue were examined on the basis of the stress analyses under the contact surface. Then the fatigue limit ρ_s under the rolling contact fatigue with specific sliding 0% and 20% could be estimated from the tensile strength σB, the yield stress σ_y and Young's modulus E as ρ0%=0.07σB√E/σ_y and ρ20%=0.05σB√E/σ_y respectively.
