As a result that a surface durability of case-carburized and hardened steels was examined using a two rollers contact fatigue testing machine, it was confirmed that the surface durability is appreciably improved by a barreling process. In the present paper, the effects of barreling process time upon surface properties of rollers were investigated under a process condition that author have currently used, and the relations between barreling process time, finished surface roughness and the surface durability were cleared. The present processes can easily be applied to a pair of Hypoid gears with a complicated tooth profile.
