Thrust bearing tests were carried out under water lubrication with hot-pressed Sialon, ZrO_2 and Al_2O_3 fine ceramics. The life of Sialon balls mating with Sialon races was the highest, and it was reduced when mating with ZrO_2 or Al_2O_3 races. The lives of ZrO_2 balls and Al_2O_3 balls mating with Sialon races were longer than those of their self-mated contact. Th friction coefficient of thrust bearings consisting of Sialon balls and/or races was comparatively small. The amount of wear of balls or races mating with Sialon was small, while that of Sialon mating with ZrO_2 or Al_2O_3 was large. The main failure modes of Sialon balls were flaking in the case mating with Sialon races, and wear in the cases mating with ZrO_2 and Al_2O_3 races. Those of ZrO_2 and Al_2O_3 balls were wear with micro flaking, and wear, respectively.
