Fatigue life tests in rolling sliding contact were carried out with the quenched and tempered JIS S45C and JIS C6241B rollers under the constant load. The tests were run with the C6241B-special aluminum bronze rollers which were attached on the high speed shaft and the S45C-carbon steel rollers which were attached on the slow speed shaft. The results are summarized as follows ; 1. It was reconfirmed that the fatigue limit of the contact surface was different when the hardness of the two testing pieces was different. 2. It was found that the surface roughness and wear of the contact surface was small, when there was some difference in the hardness. In the discrepancy of the hardness, it was found that harder one is rather better to a certain extent. The limits were from H_RA 5 to H_RA 10.
