Hot Sale Large inventory hybrid ceramic bearing 6004 with SI3N4 Ceramic ball
Ceramic Hybrid Bearings have Steel races and Ceramic Balls. Ceramic Balls are suitable for applications where high loads, high
speeds and extreme temperatures are factors. Long life and the need for minimal lubrication make this material appropriate for
extreme applications. Ceramic is non-porous, non-magnetic, non corrosive and lighter than steel. In ball form, ceramic balls are
also harder than steel and because ceramic balls are non-porous they are virtually frictionless and capable of spinning faster
than steel balls.
Ceramic Balls are usually made of following materials:
* Silicon Nitride (SiN4)
* Alumina Oxide (Al2O3)
* Zirconia Oxide (ZrO2)
* Silicon Carbide (SiC)
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.
