发明名称 Bearing manufacturing method and bearing without oxide under lubricant
摘要 There is provided a method for manufacturing a bearing, which has increased adhesive strength of lubricant to surfaces of rolling elements, a surface of a raceway or a surface of a cage. A surface of a ball, a raceway surface of an inner ring and a raceway surface of an outer ring are subjected to fluoride coating substitution process or ion bombardment process so that their oxygen concentration becomes not more than 2 ppm/mm2, by which surface oxide is removed. After the removal of the oxide, the surfaces are coated with a solid lubricant of silver, lead or the like. The surfaces from which oxide has been removed have good lubricant adhesion, making breaks in the lubricant unlikely to occur. Thus, the life of the bearing is prolonged.
