Rippling failure is well known as a plastic flow phenomenon on the surface layer of gears and rollers where sliding and rolling contact is repeated. We have already carried out some experiments using a roller testing machine, and examined the effects of the sliding velocity, the hardness of roller surface and the lubricating oil on the rippling. In the present study, we investigate the difference of the rippling occurrence due to the roller contact condition, that is, the influence of circumferential speed and relative contact position of rollers. Consequently, it is confirmed experimentally that the rippling is generated in the Hertzian contact region, whether the two rollers contact at the same position every rotation or not. Moreover, it is cleared that the generating part and the wavelength of the rippling hardly changed with increasing the load repetitions after the rippling first occurred.
