Product Description:
Ceramic bearings are typically constructed with a ferrous inner and outer ring with ceramic balls in stead of steel.
They takes many advantages over steel bearings, such as higher speed and acceleration capability, increased stiffness, lower friction and more.
Ceramic bearings are made from Si3N4 which have greater hardness than steel.
Ceramic bearing balls have smoother surface than most steel bearings balls.
They require less lubricant and exhibit lubrication degradation, which results in increased bearing life.
Ceramic bearings are applied on high temperature, high speed, friction, semiconductor and food processing and so on.

Advantages of Ceramic Bearings |
u essentially increased life time u high stiffness because of high Young’s modulus,lower vibration u wear resistance and cost effective lubrication u electrical insulation and non-magnetism u high temperature resistance up to 1000oC u high corrosion resistance to most acids and alkalies |

Product Description:
Silicon nitride ceramic bearings:the rings and balls are all silicon nitride ceramics with cages made by PTFE, PEEK etc.
Full si3n4 full ceramic bearing1s rings and balls are made from Silicon Nitride full ceramic ,PTFE cage as standard structure.Also Nylon,Peek,PI,phonelic cage are available.
Full si3n4 ceramic bearing is more suitable for higher temperature and higher load application usage.Meantime,si3n4 ceramic is applied on high speed,high precision,highest precision abec7 can be achieved.
