440C Hybrid Ceramic Ball Bearings 6900CE For Bicycle Si3N4

ceramic/hybrid deep groove ball bearing 6900CE for bicycle

1. 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. Structures

Rings(ZRO2/SI3N4)+ Retainer(PEEK/PTFE/NYLON)+Ball( ZRO2/SI3N4)

Rings(ZRO2/SI3N4) +Ball( ZRO2/SI3N4) full ball without retainer

Full Ceramic Bearing:

Full Ceramic Bearings are made entirely of ceramic material and are superior to common steel bearings in many ways. Ceramic is the perfect material for any application seeking to achieve higher RPM’s, reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present. Applications such as cryopumps, medical devices, semiconductors, machine tools, turbine flow meters, food processing equipment, robotics and optics. Ceramic materials commonly used for bearings are Silicon Nitride (Si3N4), Zirconia Oxide (ZrO2), or Silicon Carbide (SiC.)

Ceramic Balls:

We are special in making Silicone Nitride Balls (Si3N4 Balls,Zicronia Balls (ZrO2 Balls),Sic Ceramic Balls , Aluminum Oxside Valve (AI203) ceramic balls.

Compared with steel, ceramic materials are noted for their better or particular characters, such as wear-resistance, corrosion resistance, high temperature resistance, electrical insulation (except SiC), non-magnetic, high strength, high rigidity, and low specific gravity. These properties qualify them for replacing steel to make bearings serve in conditions of higher speed, harsh environment and less lube, and decrease wear, noise, vibration and maintenance time of bearings, and eventually increase performance, reliability and life of bearings.
