hybrid ceramic ball bearing
ring material : ceramic
ball material :Si3N4 and ZrO2

 Ceramic bearings for harsh environment of modern industry (corrosion, overloading, low temperature, high-speed, non-lubricated, anti-magnetic, insulating) and develop manufacturing, new materials, new processes, new structures of the perfect combination. With ceramic bearing ceramic sintering technology and manufacturing technology continues to improve ceramic bearing mass production and high cost until the perfect embodiment. She is now completely covered by the precision, speed over all-steel bearings in all applications. Silicon nitride ceramic bearing (Si3N4) than the zirconium oxide (ZrO2) better, its light weight (density of only 40% of steel), hardness (which is 2.5 times that of steel), linear expansion coefficient is small (only steel 25%), high elastic modulus (which is 1.5 times that of steel), non-conductive, non-magnetic, corrosion-resistant. Therefore, in special conditions (high-speed, high temperature, low temperature, high stiffness, high vacuum, corrosive media), the show great superiority. In the chemical industry, pharmaceutical industry, food industry, electronics industry, wind power generation, oil industry, nuclear industry has been widely used.
