Main Advantages About Ceramic Bearings

As important machinery parts, ceramic bearings have unmatched superior performances. Over the past decades, they have been increasingly widely used in many different industries such as aerospace, marine, nuclear industry, petroleum, chemical industry, textile industry, metallurgy, electric strength, food, motorcycles, subway, and high-speed machine tools and so on. Their particular function is little by little recognized by people.

With the progress of the processing technology, costs of ceramic bearings have been declined. As in the past, they can only be used in some high-accuracyn and progressive range of application areas. But now, they are little by little extended to various industries. Market prices of products are also little by little close to the functional situations. They are more permissible to the users.

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

When compared to the steel bearings, these bearings have many specific advantages. Firstly, they have higher rotating speed and speeding up capacity. They can be operated under the conditions whose DN are more than 3 million. Meanwhile, they can reduce the possibility of slipping, use and heating. Secondly, they have long service life and resistance to use.

The fatigue life of complete ceramic bearings is expected 10-50 times longer than steel bearings. already the hybrid ceramic bearings have life span which is 3-5 times longer than the steel bearings. Thirdly, they require less lubrication. Because the coefficient of friction of ceramic materials is low, already the lubricant oil becomes thin; its lubricating ability is nevertheless as good as traditional lubricants on steel bearings. Fourthly, they are more corrosion-resistant.

Ceramic materials are inert materials and it is more resistant to corrosion and abrasion. Fifthly, they have high rigidity. Due to the high elastic modulus of the ceramic materials, the rigidity of bearings is 15-20% than the ordinary steel bearings. Sixthly, they can work under high temperature. Seventhly, their torque is low. According to the structure of ceramic bearings, their torque decreases by about 1 / 3. Eighthly, they are not magnetic and not conductive. They can avoid the damage of the magnetism and the electricity.

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