Abstract:The steel ball bearing is more and more widely used in the engineering projects because of its good turning property and other advantages. In order to further improve the performances of steel ball bearing, to develop the potential of steel ball bearing and to widen its application prospect, the new high-performance friction pair material is required to use. The system composed of two objects not only directly contacting, but also producing the relative frictional motion is named as the friction pair. In the steel ball bearing, the friction pair is one of the key component parts. The friction performance and mechanical property of its materials can determine the advantages and disadvantages of the whole performance of steel ball bearing in a certain extent. The application prospect and key performance parameters of friction pair material at home and abroad are mainly introduced. And the similarities and differences of the methods of index detection in the different countries are also introduced.
