We first thought that ceramics are commonly used utensils at home, with the development of technology itself has the physical properties of ceramics are applied to all walks of life including the bearing industry. Here to tell you the advantages of ceramic bearings!
First, because the ceramic is almost afraid of corrosion, so full of ceramic rolling bearings in the corrosive medium suitable for the harsh operating conditions.
Second, the density of ceramic ball rolling lower than steel, lighter weight, much more, so rotating the external ring of the centrifugal effect can be reduced by 40%, thus greatly extending service life.
Thirdly, the ceramic by thermal expansion and contraction of small than steel, so when in the bearing clearance must be allowed to change bearings in a more severe thermal environment.
Fourth, as ceramic steel with high elastic modulus, stress is not easy deformation, it will help improve the speed of work and achieve high accuracy. ?
In summary, since the application of ceramic bearings are so many advantages, so the major imports bearing manufacturers such as: SKF Bearings, NSK Bearings, FAG bearings are related to this field and introduce the corresponding products.
Ceramic bearings and steel bearings advantages compared to
Glossary:
In recent years, countries, both inside and outside of the ceramic bearing research and development has yielded fruitful results and substantial progress. In machine tools, chemical, aerospace and other fields has been applied and play a magical effect.
Than steel bearings with ceramic bearings are magical advantages:
1, high speed and acceleration - can dn value of more than 3 million under the conditions of operation, and skidding, wear and heat can be reduced;
2, long life, resistance to wear - full ceramic bearing steel bearing fatigue life longer than expected 10-50 times, hybrid ceramic bearings, bearing life than the life of steel is about 3-5 times higher;
3 The required minimal lubrication - low coefficient of friction of ceramic materials, ceramic bearings with oil lubrication, the lubricant oil thinning or poor condition, its ability to not less than the steel bearing lubrication commonly used traditional lubricants;
4, corrosion-resistant - inert materials as ceramic materials, it is more corrosion and abrasion;
5, rigidity - due to ceramic materials with high elastic modulus, its rigid than ordinary steel, bearing a large 15-20%;
6, temperature - all ceramic bearings can work in temperatures above 500C;
7, torque low - according to the structure of ceramic bearing torque decreases by about 1 / 3;
8, non-magnetic non-conductive - Ceramic bearings can not be magnetic, electrical damage.
With a detailed study and a large number of manufacturing technology breakthroughs, ceramic bearings in high speed, high temperature, corrosion, and other fields will have very good prospects.
