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.
