High-performance ceramic bearing skill superiority summary: high-speed high-temperature low-temperature temperature difference vacuum demand insulation magnetic permeability bad working environment function ceramic bearing current use bearing bearing bearing has the customary speed scale high-speed work heating function stable life number corrosion is not afraid of pollution wear instantaneous lack of oil smooth Reliability Advanced Excellent Functional Index Ceramic Bearings Widely Used in Mechanical and Chemical Motors Vacuum Low Temperature Engineering Aerospace Category Liquid Dynamic Pressure Bearings Common Shaft Housings Shafts in harsh working environments such as high speed, high temperature, low temperature, large temperature difference, vacuum, demand insulation, non-magnetic conduction, etc. High-performance ceramic bearing is a bearing that replaces the current all-steel bearing; it has a wide range of custom speed, high-speed work, low heat, stable function, long life, corrosion resistance, no fear of pollution, anti-wear, and short-term oil-free smoothness. High-quality and excellent functional indicators for strength and reliability; ceramic bearings can be widely used in machinery, chemical, electrical, vacuum, cryogenic engineering, aerospace, aviation and other fields; broad development prospects.
The project is developed for the adjustment, heavy load, low temperature and no smooth conditions of the harsh environment in the national defense industry; the skill content is high; it is the perfect connection of new materials, new processes and new layout; its engineering temperature is D200 to Within +200; load up to 3000Mpa; dn value is less than 1.8 million mm.r/min; convert it into civilian skills; can be widely used in civilian high-speed machine tools, low-temperature engineering, high-speed motors, chemical and other occupations; through proper development; The scope of application can completely cover all the application areas of today's fine, medium-speed and above all-steel bearings; the function price ratio is far superior to all-steel bearings; the lifespan can be more than 3 times higher than the bearing life of today's use; Time; the decline of waste, the reduction of spare parts for stock bearings, etc., in addition; because of high skill content; impossible to counterfeit;
Ultra-fine ceramic balls can be widely used in high-performance bearings and high-function ball valves. Ceramic bearings can be used in high-speed machinery, light industry, instrumentation, automotive, and aerospace. These bearings are typical of two high-products; Content and high added value; is the internationally recognized mainstream product of future bearings; will occupy 40 to 60% of the bearing mall. The recent shopping mall is about 1 billion; the first use in high-speed machine tools, high-speed motors, low-temperature equipment; current development Production can gradually replace all applications of fine, medium-speed and full-bearing bearings; the price of fine ceramic bearings is 1.5 to 1.8 times that of the same type of steel bearings; and the lifespan can be extended by at least 3 times.
In addition, the automobile occupation is one of the potential application areas of ceramic bearings; the amount of ceramic bearings used in high reliability areas such as military and aviation is currently under development; the price is high; but the skill is difficult;
In summary, high-performance ceramic bearing skills have great economic benefits and extensive social benefits.

Stainless steel thread inserts are mainly 304 stainless steel, 321 stainless steel, 316 stainless steel. 304 stainless steel is a common material in stainless steel with a density of 7.93 g/cm3, also known as 18/8 stainless steel. With high temperature resistance of 800 °C, it has the characteristics of good processing performance and high toughness. 321 stainless steel is Ni-Cr-Ti type austenitic stainless steel, which has abrasion resistance, high temperature resistance, creep resistance, etc., and is used for manufacturing lining and conveying pipeline of wear-resistant acid container and wear-resistant equipment. 316 stainless steel is an austenitic stainless steel. Due to the addition of Mo element, it has a great improvement in corrosion resistance and high temperature strength. It can withstand high temperatures up to 1200-1300 degrees and can be used under harsh conditions.
