12.7mm 13mm 14mm 15.875mm 17.462mm 19mm High Precision G5 G10 Silicon Nitride Ceramic Bearing Ball Si3n4 Sic Ball
Advantages of silicon nitride ceramic ball:
1, high hardness. The Vickers hardness of ordinary Gcr15 bearing steel is 800HV, while the hardness of silicon nitride ceramic ball is more than 1700HV.
2, high wear resistance. Take the process of processing products in our company as an example, ordinary steel ball mill processing (margin of one millimeter) takes about 2-4 hours, while the silicon nitride ball processing takes at least 150-200 hours.
3, corrosion resistance. The stability of ceramic materials is the best, especially silicon nitride ball, almost no chemical reaction with any substance, widely used in petroleum, chemical, food and other industries that need to come into contact with strong oxidizing agents and strong reducing agents.
4, high temperature resistance. Ceramic ball in the sintering process to experience thousands of degrees Celsius high temperature and a lot of pressure, its internal molecular structure is very stable, the arrangement is very dense, which makes its coefficient of thermal expansion is very low, the change in temperature has almost no effect on the size of its structure. The working temperature of ceramic ball can reach 1200 degrees Celsius or even higher, low temperature also has little effect on it, so it is widely used in the aerospace field.
5, light weight. The weight of ceramic ball is only 50%-60% of the weight of ordinary steel ball, which is promising in the field of bearings and aerospace.
6, self-lubricating. Ceramic ball itself has good self-lubricating properties, high processing accuracy. Can reach G5, G10 level, ceramic ball wear-resistant as well as structural stability, not easy to deform, so it can be fine-tuned, applied to many special industries.
7, insulation. Ceramic has a good insulation effect.
