Roller chains are commonly used to transmit mechanical power in many kinds of machineries for wide industrial fields. Roller chain manufactures are doing a lot of efforts to improve the wear resistance through conventional real chain type wear testing with huge amount of time and cost. In this study, a new wear testing machine is developed to evaluate wear amounts more efficiently without using main chain components such as inner plate, outer plate and roller. The results show that the nearly same amounts of wear rate and wear status can be obtained between the newly developed wear testing machine and the conventional machine. It may be concluded that the newly developed wear testing has sufficient reproducibility and can be used more conveniently for investing roller chains compared to the conventional wear testing machine.
