Generally, a shot-peening process is utilized in order to improve the bending fatigue strength of a tooth root of a gear. In this investigation, surface durability of austempered ductile cast iron (ADI) rollers is examined using a two-rolling-contact fatigue testing machine, and it is elucidated whether or not the surface durability is improved when an ADI roller finished by a cylindrical grinding machine is subjected to an additional shot-peening process on its surface. The pitting strength of shot-peened ADI rollers is just slightly improved. Furthermore, it is shown that austempered ductile cast iron rollers are more easily worn in comparison with steel rollers which are case-carburized and hardened. In particular, shot-peened ADI rollers show large amount of wear compared with non-shot-peened ones.
