In order to elucidate the effect of an energy saving type lubricant on surface durability, steel rollers are tested under four kinds of EP gear oils with additives of V.I. improver and molybdenum disulfide using a sliding rolling contact fatigue tester. The effect of V.I. improver and the usefulness of molybdenum disulfide under ordinary Hertzian stress range could be basically understood. The fatigue life depended on coefficient of friction and surface temperature of the roller. The fatigue life and surface failure could be explained by an amplitude of ratio of stress to hardness considering the coefficient of friction, hardness distribution change due to temperature change of the roller surface and work-hardening.
