Know about the Benefits of Ceramic Bearings
Ceramic Ball Bearings as important machinery
parts have unmatched superior performances. Over the past decades, in many
different industries such as the marine, textile industry, nuclear industry,
petroleum, metallurgy, aerospace, food, chemical industry, motorcycles,
electric power, subway, and high-speed machine tools and so on they have been
widely used. People are gradually recognizing their particular functions.
Costs of ceramic bearings have been declined with the
progress of the processing technology. In the past, they were used only in some
high-precision and advanced range of application areas. But now, they are
gradually going to various industries. Prices of market products are also
gradually close to practical situations. They are highly acceptable to users
.
In recent years, research and development done on full
ceramic ball bearing has achieved substantive progress and yielded
fruitful results. They have been successfully applied in chemical industries,
aerospace, machine tools, and many other fields.
These bearings have many specific advantages compared to the
steel bearings. At first, they have higher rotating speed and acceleration
capacity. Under the conditions where DN is more than 3 million, they can be
operated. Along with this, they can reduce the possibility of heating, slipping
and wear. Secondly, to long and wear service life, they have resistance.
Ceramic materials are more resistant to corrosion and
abrasion and are inert materials. Fifthly, their rigidity is quite high. The
rigidity of bearings is 15-20% compared to the ordinary steel bearings and this
is because of the high elastic modulus of the ceramic materials.
Sixthly, even at high temperatures, they can work.
Seventhly, they have low torque. Their torque decreases by about 1 / 3
according to the structure of ceramic hybrid bearings. Eighthly,
they are not conducive and not magnetic. The damage of the magnetism and the
electricity can be avoided by them.
According to the above, we can now come to the conclusion
that ceramic bearings are increasingly important in our industries. The
application of ceramic bearings under the condition of high speed, high the temperature will have very good prospects with the development of the research
and a large number of manufacturing technology breakthroughs.
