1-3mm semiconductor Si3n4 Description
Silicon nitride ceramic bearings are an important mechanical part. They are often used in new materials because they work very well. They are better than other bearings. Silicon nitride is not the hardest material in industrial ceramics or the material with the highest toughness. But it is best suited for bearings that need to perform well.
In general, if steel bearings are used at temperatures above 120°C, they become less solid and their service life is shortened. Centrifugal forceThe density of steel used in bearings is about 7.8 × 103 kg/m3, and the density of silicon nitride is about 3.24 × 103 kg/m3, which is only about 40% of the density of steel. Therefore, when ceramic balls are used as rolling elements in a bearing, the bearing can stop the increase in the load on the rolling elements caused by centrifugal force when the bearing is rotating at high speed.
