摘要： PROBLEM TO BE SOLVED: To provide a rolling bearing whose useful life is adequately extended even under high-speed rotation with dmn value of 1.4 million or more, or in a corrosive environment not allowing the use of a lubricant. SOLUTION: A ball 3 is manufactured by the following method. Silicon nitride spherical bodies are put in the mill pot of a planet ball mill, and the planet ball mill is actuated. Centrifugal force resulting from revolution and that resulting from rotation generated in the mill pot are given to these spherical bodies, thereby making the spherical bodies collide with each other, and moreover, making them collide with the inner wall of the mill pot. Then, finish polishing is performed after a ball mill process for introducing displacement in ceramics crystals forming the surfaces of the spherical bodies is performed. In the ball mill process, the compressive residual stress of a surface layer is set to be not less than 500 MPa. COPYRIGHT: (C)2008,JPO&INPIT
