| titleOfInvention | Ball bearing |
| abstract | (57) [Problem] To provide a ball bearing which can prevent ball separation even at high temperature and high speed and can improve lubricity at high temperature and high pressure. According to this ball bearing, since an oxide film is formed on the surface of the ball, the oxide film acts as a buffer material in combination with an oil film of grease, and the stress on the ball surface is increased. The concentration is alleviated to prevent the ball 4 from peeling off. Therefore, according to this ball bearing, the separation of the ball 4 can be prevented even under high temperature and high speed rotation, and lubricity at high temperature and high pressure can be improved. |
