There is provided a method for manufacturing a bearing, which has been increased in adhesive strength of lubricant to surfaces of rolling elements, a surface of a raceway or a surface of a cage. A surface 6 of a ball 4, a raceway surface 7 of an inner ring 2 and a raceway surface 8 of an outer ring 3 are subjected to fluoride coating substitution process or ion bombardment process so that their oxygen concentration becomes not more than 2 ppm/mm<2>, by which oxide of the surfaces 6, 7, 8 is removed. After the removal of the oxide, the surfaces 6, 7, 8 are coated with a solid lubricant of silver, lead or the like. The surfaces 6, 7, 8 from which oxide has been removed have good lubricant adhesion, making the breaks of the lubricant unlikely to occur. Thus, the life of the bearing is prolonged. <IMAGE> |
