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:

 

1.High precision bearings,P4 ,P5 and P6.

 

2.Rings are made of refined Chrome steel.stainless steel 440C3.Cage:Peek & PTFE cage .(can assure constant working under 250 centigrade)and peek cage also is the ideal cage for the high speed as it can provide the lubrication during  bearing working, and it has the property of self-lubrications.However for normal applications, steel cage and Nylon cage is enough.4. Balls: we use G3,G5 high precision Si3N4 ball for the high speed.5. Radial clearance: Normal C0,or C3.6.Not only for the high speed, but also Hybrid bearings has theinsulation functions. Hence for the small size of bore dia.40mm ,also can be used for the insulation bearing purpose.7.Full ball hybrid also can be produce as per our production picture.

 

Properties:

llceramic bearings have good to excellent corrosion resistance, are nonmagnetic and, apart from silicon carbide, 

 

are electrically insulating. Allceramic bearings can be used in high to very high temperatures if supplied without 

 

a cage (full complement).Electrical resistance: Si3N4 best, then ZrO2, then SIC which is conductive.

 

Allceramic bearings have lower load and speed ratings than steel or hybrid bearings. The speeds are lower due 

 

to the lower precision and roundness of the rings and the loads are lower because the material is more brittle. 

 

Under heavy loads and particularly heavy shock loads, there is a risk of cracking. For the same reason, great c

 

are should be taken with interference fits. Zirconia is the least brittle so it will handle shock loads and very small 

 

interference fits better than the other ceramic materials with silicon carbide being the most brittle. Shock loads 

 

should be avoided with allceramic bearings. Great care should be taken when using ceramic bearings (especially 

 

silicon nitride and silicon carbide) on steel shafts at high temperature due to the difference in expansion coefficient 

 

and the relative brittleness of ceramics.
