Introduction of ceramic rolling bearing manufacturing materials - silicon nitride


    It comes to the manufacture of ceramic rolling bearing material, silicon nitride ceramics.contact ball bearing According to the information reported, the two Nova rise of modern ceramics - silicon nitride and silicon carbide have amazing resistance to high temperature.angular ball bearing Silicon nitride ceramic at 1400 ° C, silicon carbide ceramics at 1700 ℃, the strength is still up to every square centimeter 7000kg, while most metals this time has long been softened or melted into liquid.cross bearing
