Full Ceramic ball bearing of Zirconia deep groove ball bearing 6204 with high quality


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

ZrO2 bearings can work in terrible conditions while the ordinary bearings can not be qualified. 
And the cost is much lower than the silicon Nitride ceramics bearings. 

It is widely used in aviation,aerospace,marine,pertroleum,chemical, automotive,,electronics,metallurgy,electric power,textile, medical equipment and other fields.

The rings of ZrO2 bearings that our company produces are made of by bearing steel,

stainless or zirconia ceramic. And the rolling are with the use of zirconia ceramic material. 

The cage is made by telon , nylon66,Poly-ether acid sub-ammonia, stainless steel, which extends the application of ceramic bearings, shielded bearings, electrical insulation bearings and so on. 

We also produce deep groove ball bearing. full compliment balls, self-aligning ball bearings,angular contact bearings,insert bearing of all ceramic and hybrid construction ceramic ball bearings.

a) How to prolong service life of bearings?

 Accurate installation and using,alignment,timely monitor,re lubrication etc.

b) Reason for bearings failure?

  Usually is incorrect using method,pollution,improper use of lubricant,damage happened in installation and handing,also including installation error.according to the traces can know the reason why is failure.

c) How to choose bearings?

  Analyse mechanical device and use conditions.clear the requiremment of bearings.select type of bearings,select distribution way of bearings.selet dimensions of bearings,select installation method of bearings.

d) When select bearings specifications,what you need to consider?

 The precision of the bearings(rotating precision,dimensional tolerances)internal clearance and preload bearing material and heat treatment.structure of cage and material.

 e) Payment method,packing way,transport method,time of delivery?



     By sea,by air

       3-15days after receipt of payment.
