    The Brief Introduction of Ceramic Ball Bearings:

    Compared to steel, Ceramic ball Bearings have many specific advantages. They offer superior corrosion and heat resistance, higher dimensional stability, and lower density, which facilitate high speed. Ceramics are superior to steel in heat and corrosion resistance, and are lightweight and extremely hard as well. Consequently, ceramic rolling bearings can be used in environments where conventional steel bearings cannot. That is to say, the superiority of these bearings makes it possible that they can be applied in some special environments.

    Hybrid Ceramic Bearing:

    Ceramic bearings offer a significant performance improvement from those made from traditional steel. Our ceramic bearings are manufactured from silicon nitride (Si3N4), an exceptionally hard non-metallic material rated for speeds to 2 million dN, offering a wide selection of benefits.

    Hybrid Bearings have steel rings and ceramic balls. Si3N4 Ball is the most popular for the balls as it has only 40 percent of the density of bearing steel but is much harder giving greater wear resistance. Zirconia is heavier with 75 percent of the density of steel so is less suitable for hybrid bearings..

    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.

    Ceramic Bearing Benefits :

    • Will not corrode or rust
    • 2/3 the weight of steel
    • Resistant to resist acids, alkali, blood, salt and water
    • Extremely low coefficient of friction and thermal expansion
    • Lower friction results in less energy consumed
    • Operating Temperature from as low as (-85°C) up to (+ 900°C)

    Ceramic Bearing Applications :

    Full Ceramic ball bearings are used in specialty applications like chemical baths, vacuum environments, semiconductor manufacturing, food processing industries and more. Any extreme environment that requires non-corrosive, non-conductive or non-magnetic bearings is ideal for full ceramic bearings.
