ZnO-coated high-performance bearings developed

A research group consisting of National Institute for Materials Science (NIMS) and Tohoku University developed a coating technique using a zinc oxide (ZnO) material, an environment-friendly, low-friction material developed exclusively by NIMS. When bearing balls were coated with the ZnO material, the material's low frictional characteristics were maintained and the friction coefficient of the bearing was reduced by approximately one-third.
