Material Introduction
Silicon nitride ceramic balls have high strength, good wear resistance, high rigidity, corrosion resistance, high temperature resistance, electrical insulation, non-magnetic conductivity, small specific gravity and other properties that are not available in a series of metal materials. They are a good choice for material of high temperature structural products, as well as ceramic bearings.
Material Application
high-precision ceramic bearings, high temperature bearings, vacuum bearings, non-magnetic bearings, chemical pumps, high temperature pumps, ceramic valve balls, measuring balls.
Our company adopts advanced powder processing and air pressure sintering technology to produce high-quality silicon nitride ceramic bearing balls and valve balls. The specifications are from 0.4mm to 60mm in diameter, and the machining accuracy is G5, G10, G20, G40-G100.
