As for pitting, it is a phenomenon which is coused when the contact stress of a certain strength over the limit is repeated about 10^6 times. The phenomenon has much to do with such machine elements as antifriction bearing, gear, and rolling mill. And pitting confined the conditions of usage and the endurance of materials. Therefore ; in order to prolong the endurance of these mechanical elements, it is important to analyze the rolling condition of these mechanical elements, the characteristics of pitting of materials, and influence of surface finishing and heat treatment upon pitting. In this paper, pitting strength of normalized carbon steel was studied by using a Nishihara type testing machine under spindle oil lubrication condition with sliding. Effect of surface finishing on the fatigue life under contact stress were investigated throuth wearing loss anH roughness measurement, visual observation wearing surface
