NOUN explanation:
In recent years, both at home and abroad, the research on ceramic bearing, development has achieved fruitful results and substantial progress. Has been used to perform magic effect in machine tools, chemical, aerospace and other fields.
Ceramic bearings are all steel bearing has the following advantages of magic:
1, speed and acceleration of high - value more than 3000000 operating conditions in the DN, and slip, abrasion and heat can reduce;
Fatigue life of 2, long service life, wear - full ceramic bearing steel bearing is expected to more than 10 - 50 times, hybrid ceramic bearing, life is better than all steel bearing life of 3-5 times;
3, the coefficient of friction - Lubrication ceramic materials are low, the ceramic bearings, lubricating oil in the thinning or lean conditions, the lubricating ability is not lower than that of conventional steel bearings commonly used lubricants;
4, wear and corrosion - as a result of ceramic materials as inert material, it is more resistant to corrosion and abrasion;
5, the rigid - because the elastic modulus of ceramic materials with high, its rigidity than ordinary steel bearing 15-20%;
6, high temperature resistant, ceramic bearing temperature above 500C work;
7, low - torque according to the structure, the ceramic bearing torque is reduced by about 1/3;
8, no damage to magnetic nonconductive -- ceramic bearings without magnetic, electric.
With the in-depth study and a large number of manufacturing technology breakthroughs, application prospect of the ceramic bearings in high speed, high temperature, corrosion and other areas will be very considerable.
