陶瓷轴承主要特性 随着现代化设备的发展需求，客户对轴承的要求相对也就要

The main characteristics of ceramic bearings <br>with the development needs of modern equipment, customer requirements for bearings also relatively demanding. Ceramic bearings can meet the requirements of various harsh working conditions, and their characteristics are introduced as follows: <br><br>1. The bearing capacity of <br><br>ceramic bearings is very high. The material hardness can be up to 2 times that of bearing steel, and the elastic modulus is 1.5 times that of bearing steel. Therefore, ceramics The bearing capacity of the bearing is much higher than the bearing made of bearing steel. <br>2. <br><br>The ceramic materials used in ceramic bearings with good heat resistance will not change much at high temperature. Even if the difficulty is 800oC, I can still maintain high strength and performance, and the thermal expansion rate of ceramic materials is only It is 22% of the bearing steel, so the dimensional stability under high temperature environment will be very good. <br>3. <br><br>The normal working speed of ceramic bearings with high limit speed can reach more than 1.3 times of that of the same type of steel bearings, and it will not deform and change its structure due to high temperature caused by high speed. <br>4. Small frictional heating during operation. The temperature rise of <br><br>ceramic bearings when working at a speed of 18000r / min is 60% of the temperature rise of ordinary bearings of the same model. <br>5. The friction loss is small <br><br>. For ordinary bearings of the same model, the material quality of ceramic bearings is relatively small. (Approximately 40% of bearing steel), the centrifugal force and gyro torque received during operation are small, and the spin slip is small, so the friction loss is significantly smaller than the bearing steel bearing. <br>6. High durability. <br><br>Ceramic bearing materials have high hardness and excellent wear resistance. The working life of ceramic bearings is generally more than twice that of ordinary bearing steel bearings. <br>7. Good corrosion resistance The <br><br>materials used for ceramic bearings can resist the corrosion of various organic acids and inorganic acids such as hydrochloric acid, sulfuric acid, nitric acid, caustic soda and burnt metal, but in hydrogen oxide and molten iron, the corrosion performance is poor. Pay attention to it during use.
