The service life of variant crowned roller could be increased by 2 to 3 times for evener stress distribution, normally longer. The surface process of high-precision cylindrical roller adopts crowned super-precision technology. The roughness of surface will decrease and round deviation will be improved and cross net remained will make surface reserve oil film for coating after super-precision treatment so as to reduce noise and vibration of bearing for longer lifespan and to improve performance
