Rolling bearing material including material and keep rolling bearing components, rivets and other auxiliary materials. The vast majority of the steel rolling bearing and its parts, rolling bearing steel is usually a high carbon chromium steel and carburizing steel. With the development of modern science and technology and rolling bearing usage is increasing, more and more high to the requirement of bearing, such as high precision, long life and high reliability, etc. For some special purpose bearings, bearing materials are also required to have high temperature resistant, corrosion resistant, nonmagnetic, properties, such as temperature, radiation resistance. In addition, bearing materials include alloy materials, non-ferrous metals and non-metallic materials. In addition, made of ceramic bearing has been used in motorcycle, automobile, subway, aviation, aerospace, chemical industry, etc.
