Ceramic bearings are very good bearings, many people prefer to use ceramic bearings. At present, many brands imported bearings have ceramic bearings, why so many people like ceramic bearing it? That is because the ceramic bearing has its merits, the present ceramic bearing is very good. So over all-steel bearings ceramic bearing, what advantage? We turn next to discuss on this issue.
In recent years, countries, both inside and outside of the ceramic bearing research and development has achieved fruitful results and substantive progress. In the machine tools, chemical, aerospace and other fields has been applied and play a magical effect.
Than the all-steel bearings with ceramic bearings are magical advantages:
1, high speed and acceleration - can be dn value more than 3 million under the conditions of operation, and the skid, wear and heat can be reduced;
2, long life and resistance to wear and tear - all ceramic bearing fatigue life is expected to 10-50 times longer than steel bearings, hybrid ceramic bearing, life expectancy higher than the all-steel bearing life 3-5 times;
3, the required minimal lubrication - ceramic materials with low coefficient of friction, using oil lubricated ceramic bearing, in the lubricant thinning or depleted oil cases, the lubricating capacity of not less than the traditional steel bearing lubricant used;
4, corrosion-resistant - ceramic materials as inert materials, it is more resistant to corrosion and wear;
5, rigid - a result of ceramic materials of high elastic modulus, its rigid than ordinary steel bearing large 15-20%;
6, temperature - all-ceramic bearings in 500. C at temperatures above work;
7, torque and low - according to the structure of ceramic bearing torque decreases by about 1 / 3;
8, non-magnetic non-conductive - Ceramic bearings can be free from magnetic, electric damage.
With the in-depth research and a large breakthrough in manufacturing technology, ceramic bearings in high speed, high temperature, corrosion and other fields will be very considerable prospect.
