Rolling bearing's production characteristic, had decided below its technological process has three big characteristics: 1. specialized in the bearing part processing, uses the bearing special purpose equipment massively. If the steel ball processing uses rubs, grinder equipment and so on ball machine. The specialized characteristic also manifests in the bearing part production, like specialized production steel ball steel ball company, specialized production miniature bearing's miniature bearing factory and so on. 2. automated the bearing produces the specialty changed into its production automation to provide the condition. Uses the completely automatic, the semiautomation massively in the production special-purpose and the non-special purpose machine, and produces the automatic line to promote the application gradually. If heat treatment from generatrix and assembly from generatrix and so on.because 3. advanced the bearing produces the mass scale request, causes its use advanced engine bed, the work clothes and the craft possibly becomes. Like numerically-controlled machine tool, three fingernail fluctuation chuck and protective atmosphere heat treatment and so on.
