ZLYGCB018 99% Alumina Full Ceramic Bearing

 Alumina ceramic bearings are made of alumina ceramics with an alumina content of 99%. The rolling elements are also made of alumina ceramics.
The main properties of alumina are as follows:
High wear resistance; in the high frequency range from DC to gigahertz, its dielectric properties are excellent; at high temperatures, it is resistant to various strong acids and alkalis; good thermal conductivity; excellent dimensional and shape stability; high strength and hardness. Alumina with a purity of 94% to 99.5% can easily form metal composites and can be used in high temperature applications.
