Major Benefits about Ceramic Bearings

by James Gooding Custom Bearing Manufacturer

Hybrid ceramic bearings as important machinery parts have unmatched superior performances. In many different industries such as marine, aerospace, petroleum, nuclear industry, textile industry, chemical industry, electric power, metallurgy, motorcycles, food, high-speed machine tools, and subway and so on, they have been increasingly widely used over the past decades. People recognize their particular function gradually.

Costs of ceramic bearings have been declined with the progress of the processing technology. They can only be used in some advanced range of application and high-precision areas as in the past. But now to various industries, they are gradually extended. In practical situations, Market prices of products are also gradually close. To the users, they are more acceptable.

In recent years, development and research on ceramic bearings have achieved substantive progress and yielded fruitful results. They have been applied in aerospace, chemical industries, machine tools, and many other fields. Obviously in the industries, they play a rather important part.

These bearings have many specific advantages when compared to the steel bearings. Firstly, they have acceleration capacity and higher rotating speed. Under the conditions, they can be operated whose DN is more than 3 million. Meanwhile, they can reduce the possibility of heating, wear, and slipping. Secondly, they have resistance to wear and long service life.

As compared to hybrid ceramic ball bearings, the fatigue life of full ceramic bearings is expected 10-50 times longer. As compared to the steel bearings, even the hybrid ceramic bearings have a life span which is 3-5 times longer. Thirdly, less lubrication is required. The lubricant oil becomes thin because the coefficient of friction of ceramic materials is low, even; its traditional lubricants are still as good as lubricating ability on steel bearings. Fourthly, they are more resistant to corrosion.

It is more resistant to abrasion and corrosion and Ceramic materials are inert materials. They have more rigidity. The rigidity of bearings is 15-20% than the ordinary steel bearings due to the high elastic modulus of the ceramic materials. Under high temperatures, they can work. Seventhly, it has low torque. Their torque decreases by about 1 / 3 according to the structure of ceramic bearings. Eighthly, they are not conducive and not magnetic. They can avoid damage to electricity and magnetism.

According to the above, we can safely conclude that in our industries, ceramic bearings are increasingly important. The application of hybrid ceramic bearings under the condition of high temperature, high speed will have very good prospects for a large number of manufacturing technology breakthroughs and with the development of the research.
