Advantage of Ceramic Bearing

1.High-speed: Ceramic bearings have the advantages of cold resistance, low elasticity, high pressure resistance, poor thermal conductivity, light weight, and low friction coefficient. They can be used in high-speed spindles and other high-precision equipment from 12,000 to 75,000 rpm.2.High temperature resistance: The ceramic bearing material itself has a high temperature resistance of 1200 degree, and a good self-lubrication. No expansion will be caused due to temperature differences between 100…
