High Precision Spherical Roller Bearings for Vibratory Applications Plastic Wheel

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.

    1. Higher limit speed:

    Ceramic is lighter than steel and can effectively restrain the centrifugal force, therefore enhances the limit speed.

    2. Higher precision usage:

    Ceramic has hardness and elastic modulus than steel which means ceramic bearing is stiffer more rigid than steel bearing thus can be used in higher precision condition.

    3. Longer life:

    Lighter ceramic leads to lower centrifugal force, thus extends bearing life. Furthermore friction coefficient of ceramic is lower than steel which also extends bearing life.
