High temperature bearing is a kind of bearing that can stand high temperature. There are many kinds of high temperature bearing, according to different needs, different environments, different types of bearings can be installed.

In normal operation, the bearing shall not be stuck and abnormal noise. At the same time, the imported high-temperature bearing shall bear the influence of vibration, impact and other factors. The materials used for the bearing shall be wear-resistant, non-magnetic and corrosion-resistant.

According to the special working condition of imported high temperature bearing, the material of ferrule and ball should have the characteristics of high temperature resistance, corrosion resistance, wear resistance and non magnetism. It is suggested to use G52 alloy as ferrule material and Si3N4 or cermet as ball material.
