| Abstract: | The metallographical structure and the processing method of the bearings that improve their stability are investigated. It is found that adoption of cryogenic treatment is able to reduce the content of austenite residuum after steel quenching as well as the density of spot defect in the steel, so that the influencing factor of metallographic structure on the dimension of the work piece is reduced. |

| Keywords: | bearing steel cryogenic treatment austenite residuum |
