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

essentially increased life time

high stiffness because of high Youngs modulus,lower vibration

wear resistance and cost effective lubrication

electrical insulation and non-magnetism

high temperature resistance up to 1000oC

high corrosion resistance to most acids and alkalies

It can been applied in kiln,plastic,steel and other equipments that can bear high temperature

 

1.High speed bearings: 12000rpm-75000rpm                                                              

2.High temperature-resistant bearings:100oC--800 oC.

It can been applied in kiln,plastic,steel and other equipments that can bear high temperature

3.Corrosion-resistant bearings

4.Electric-insulated bearings

5.Vacuum bearings:self-lubricating without oil
