Ceramic Bearing Excellent Performance, High Temperature
Sep 28, 2017

With the development of science and technology ceramic itself has the physical properties applied to all walks of life, including the bearing industry. Ceramic Bearing as an important mechanical foundation pieces, because of its metal bearings can not match the excellent performance, high temperature, super strength in the world of new materials dominate the world

Over the past decade, Ceramic Bearing in the national economy and people in various fields has been increasingly widely used. Here to introduce the advantages of Ceramic Bearing:

First, because the ceramic elastic modulus than steel, stress is not easy to deformation, it is conducive to improve the working speed, and to achieve high accuracy.

Second, because the ceramic is almost not afraid of corrosion, so the ceramic rolling bearings suitable for corrosive media in the harsh conditions of operation.

Third, the impact of thermal expansion and contraction of the ceramic than steel, and thus a certain gap in the bearing, the bearing can be allowed to change the temperature in the more intense environment to work.

Fourth, because the ceramic rolling ball density is lower than the steel, the weight is much lighter, so the rotation of the outer ring when the centrifugal effect can be reduced by 40%, and thus greatly extend the service life.

In summary, due to the Ceramic Bearing in the application of so many advantages, so the major import bearing manufacturers such as: SKF bearings, NSK bearings, FAG bearings are related to this area and the introduction of the corresponding products.

With the continuous improvement of processing technology, the increasing level of technology, the cost of Ceramic Bearing has been declining, from the past only in a number of high, refined, sharp areas of small applications, and gradually extended to the various sectors of the national economy, product market prices Also gradually close to the practical, to the user acceptable level, Ceramic Bearing, a large area of application of the wave has come.

Ceramic bearing performance and price ratio is far superior to all steel bearings, life than the current use of bearing life more than 3 times, can save a lot of downtime maintenance time, reduce the rejection rate, reduce the stock bearing spare parts. In the case of

Compared with the bearing steel performance, the weight is 30% -40% of the bearing steel, can reduce the centrifugal force generated by the increase in moving load and slip. Due to high wear resistance, the speed is 1.3-1.5 times the bearing steel, can reduce the high-speed rotation of the channel surface damage. The modulus of elasticity is 1.5 times higher than that of bearing steel. The elasticity of the force is small, and the deformation due to the high load can be reduced. Hardness is 1 times the bearing steel, can reduce wear. Compression is 5-7 times the bearing steel. Thermal expansion coefficient is less than 20% of bearing steel. The friction coefficient is less than 30% of the bearing steel, can reduce the heat generated by friction, can reduce the high temperature caused by the bearing before the peeling failure. Tensile, bending and metal equivalent. Imported bearings

Ceramic Bearing with high temperature, cold, wear, corrosion resistance, anti-magnetic insulation, no oil self-lubricating, high speed and other characteristics. It can be widely used in the fields of aviation, aerospace, navigation, petroleum, chemical, automobile, electronic equipment, metallurgy, electric power, textile, pump, medical device, scientific research and national defense military. New materials used in high-tech products. Ceramic bearing rings and rolling body with all-ceramic materials, zirconia (ZrO2), silicon nitride (SisN4), silicon carbide (Sic) three. The holder is made of polytetrafluoroethylene, nylon 66, polyether imide, zirconia, silicon nitride, stainless steel or special aviation aluminum, thus expanding the application of Ceramic Bearing. Applications: medical equipment, low temperature engineering, optical instruments, high-speed machine tools, high-speed motors, printing machinery, food processing machinery.
