Silicon Nitride Ceramics Are Gradually Becoming The Material Choice For Ceramic Bearings

 

Advantages of Silicon Nitride Ceramics:

First, the reason why silicon nitride ceramic bearings can work under certain environments and situations benefits from the function of si3N4 ceramics. Friends who have some understanding of si3n4 ceramics know that the elastic modulus of silicon nitride is much higher than that of metal, and the elastic deformation after force can reduce the oscillation of the machine tool to a certain extent.

 

Second,because silicon nitride ceramics have high hardness, the bearings made of si3n4 ceramics have very good wear resistance. In addition to these, the mechanical strength of silicon nitride ceramic is also very high, its tensile strength and flexural strength are similar to metal, and the compressive performance is very strong, especially under high temperature conditions, si3N4 bearings can still adhere to high strength and hardness, silicon nitride and other material bearings compared with bearings, si3N4 ceramic bearings are longer.

We all know that the friction coefficient of silicon nitride ceramic is very small, si3N4 bearings have low heat generation performance, and compared with metal materials, the thermal conductivity function of silicon nitride ceramics is very poor, resulting in silicon nitride ceramic bearings in the operation of the heat is very small. Therefore, si3N4 bearings have received the love of many industries.
