Silicon nitride is very strong, especially hot-pressed silicon nitride, which is one of the hardest materials in the world. It has high strength, low density, high temperature resistance and other properties. It is extremely resistant to high temperatures, and its strength can be maintained to a high temperature of 1200°C without falling. It will not melt into a melt after being heated, and will n...

The Features Of Small Plastic Ball Bearing : 1. The whole plastic bearing is lubricating material with long service life; while the lubricating layer of metal sliding bearing is only 0.003mm PTFE on the surface, when this thin layer of friction is finished, it will declare the end of service life; 2. The use of plastic bearings will not rust and is corrosion resistant, and metal bearings are easy ...
