6903 ceramic bearing bicycle wheel bearing Hybrid Ceramic Bearings


6903 ceramic bearinghybrid ceramic bearings


6903 ceramic bearing have characteristics of strong resistance against all kinds of acid, alkali, salt and other corrosive medium erosion, against high temperature, wear-resistant, lightest structure weight, high limiting speed, low noise, electrical insulation, dimensional stability at high temperature, small starting torque etc.  They can be used in worse lubrication working condition with a long operating life. They are widely applicable in aviation, aerospace, marine, petrolium,chemical, mechanical, automobile, motocycle, metallurgy, electronics, textiles pumps, pharmaceutical, food machinery, medical equipment, national defence and military technology, etc.,thus becoming a new kind of high-tech

1. 6903 ceramic bearing Material peroformance 

Full ceramic bearing ZrO2 material
Full ceramic bearing ZrO2 material has great property such like suitable for low and high temperatures, high load capacity, corrosion resistance, nonmagnetic insulated and self lubrication. Thus it suit for the specific applications which are not available for bearing steel and hybrid construction ceramic ball bearing materials.
Full ceramic bearing Si3N4 material 
Full ceramic bearing Si3N4 material has similar property as ZrO2
material, In addition; it has lower weight , better wear resistance, high hardness, and it can bear higher temperature than ZrO2 material. 

2. Ceramic Bearing Structures 

Rings(ZRO2/SI3N4)+ Retainer(PEEK/PTFE/NYLON)+Ball( ZRO2/SI3N4)
Rings(ZRO2/SI3N4) +Ball( ZRO2/SI3N4) full ball without retainer

3. Ceramic Bearing Performance 

a.Powerful corrosion resistance - Using possible in strong acid, alkali, sea water
b.Heat-resisting property - No hardness and strength change at high temperature
c.Non-magnetism, insulation resistance - Using possible at magnetic field, prevention of electricity  origination
d.Light weight - More light than normal bearing’s 1/4
e.High rigidity - Hardness, straight elasticity coefficient is higher than bearing steel
f.High-speed revolution - The electro motion(ball) is so light that decrease the centrifugal force when it revolute

4. Ceramic Bearing Applications 

Chemistry Industry; Medical Field; food Machinery; Printing Machinery; Electronic Equipment; petroleum Industry (Semiconductor, PDP, LCD)Manufacturing Equipment Composition fiber; Manufacturing Equipment Optic film Equipment and Vacuum Equipment.
