Si3N4 Silicon Nitride Full Ceramic Ball Bearing Full Balls Bearings Various size
Description:
-Material: Silicon Nitride
-The inner and outer rings of silicon nitride ceramics are made of silicon nitride material. It is a superhard material, which has lubricity and wear resistance. It is atomic crystal; it is resistant to oxidation at high temperature.
-Silicon nitride ceramic balls have high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance, can be used in seawater for a long time, and have good performance of electrical insulation and magnetic insulation.
-Stable rotation and smooth resistance are small, and the working speed of the ceramic ball bearing can reach more than 1.3 times the limit speed of the same type of bearing steel. And ceramic materials have high hardness and good wear resistance, and the working life of ceramic ball bearings is generally more than 2 times that of ordinary bearing steel bearings.
-Silicon nitride full ball full ceramic bearing can withstand high temperature 1200°C
-Main uses: Ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, anti-magnetic and electrical insulation, oil-free self-lubrication, high speed and so on. It can be used in extremely harsh environments and special working conditions, and can be widely used in aviation, aerospace, navigation, petroleum, chemical, automotive, electronic equipment, metallurgy, electric power, textiles, pumps, medical equipment, scientific research and defense and military fields. High-tech products for new material applications.
