In recent years, research and development of ceramic bearings at home and abroad have yielded fruitful results and substantial progress. It has been applied in machine tools, chemical industry, aerospace and other fields and has played a magical effect.
Ceramic bearings have the following magical advantages over all-steel bearings:
1, the speed and acceleration ability is high - can run under the condition that the dn value exceeds 3 million, and the slip, wear and heat can be reduced;
2, long life and wear resistance - the fatigue life of all ceramic bearings is expected to be 10-50 times longer than all steel bearings, hybrid ceramic bearings, life is also 3-5 times higher than the life of all steel bearings;
3, the required lubrication is very small - the ceramic material has a low friction coefficient, using oil-lubricated ceramic bearings, in the case of lubricating oil is thin or lean, its lubricating ability is still not lower than the traditional lubricant commonly used in steel bearings;
4, wear-resistant - because the ceramic material is an inert material, it is more resistant to corrosion and wear;
5, the rigidity is large - due to the high modulus of elasticity of ceramic materials, its rigidity is 15-20% larger than ordinary steel bearings;
6, high temperature resistance - all ceramic bearings can be at 500. Working above C temperature;
7, low torque - according to the structure, the torque of ceramic bearings is reduced by about 1/3;
8, non-magnetic and non-conductive - ceramic bearings can be protected from magnetic and electrical damage.
With the deepening of research and breakthroughs in mass manufacturing technology, the application prospects of ceramic bearings in the fields of high speed, high temperature and corrosion resistance will be considerable.
