Comparison of the properties of four bearing materials: ordinary bearing steel AISI52100 (GCr15), stainless steel AISI440 (9Cr18), silicon nitride (Si3N4), and zirconia (ZrO2). Incomparably excellent performance, high-temperature resistance, super strength, etc. are leading in the world of new materials. In the past ten years, it has been increasingly widely used in various fields of the national economy and people's livelihood.advantageceramic bearingFirst, because ceramics are almost not afraid of corrosion, ceramic rolling bearings are suitable for operating under harsh conditions full of corrosive media.Second, because the density of the ceramic rolling ball is lower than that of steel, the weight is much lighter, so the centrifugal effect on the outer ring can be reduced by 40% during rotation, and the service life is greatly extended.Third, ceramics are less affected by thermal expansion and contraction than steel, so when the clearance of the bearing is constant, the bearing can be allowed to work in an environment with severe temperature changes.Fourth, since the modulus of elasticity of ceramics is higher than that of steel, it is not easy to deform when stressed, so it is beneficial to improve the working speed and achieve higher precision.Ceramic bearings have the characteristics of high-temperature resistance, cold resistance, wear resistance, corrosion resistance, anti-magnetic and electrical insulation, oil-free self-lubrication, high speed, and so on. It can be used in extremely harsh environments and special working conditions and can be widely used in aviation, aerospace, navigation, petroleum, chemical industry, automobiles, electronic equipment, metallurgy, electric power, textiles, pumps, medical equipment, scientific research and national defense and other fields. High-tech products with new material applications.The rings and rolling elements of ceramic bearings are made of all ceramic materials, including zirconia (ZrO2), silicon nitride (Si3N4), and silicon carbide (Sic). The cage is made of polytetrafluoroethylene, nylon 66, polyetherimide, zirconia, silicon nitride, stainless steel, or special aviation aluminum, so as to expand the application surface of ceramic bearings.Medical equipment, cryogenic engineering, optical instruments, high-speed machine tools, high-speed motors, printing machinery, and food processing machinery.In the fields of aerospace, navigation, nuclear industry, petroleum, chemical industry, light textile industry, machinery, metallurgy, electric power, food, locomotive, subway, high-speed machine tools and scientific research, national defense,, etc. Working under special conditions such as explosive, strong corrosion, vacuum, electrical insulation, non-magnetic, dry friction, etc., ceramic bearings are gradually being recognized as an indispensable substitute.(1) High-speed bearings: have the advantages of cold resistance, small elastic force, high-pressure resistance, poor thermal conductivity, lightweight, small friction coefficient, etc., and can be applied to high-speed spindles of 12000 rpm-75000 rpm and others In high-precision equipment;(2) High-temperature resistant bearing: The material itself has a high-temperature resistance of 1200°C and is self-lubricating well, and the operating temperature does not cause expansion due to temperature differences between 100°C and 800°C. It can be used in high-temperature equipment such as kilns, plastic making, and steel making;(3) Corrosion-resistant bearings: The material itself has the characteristics of corrosion resistance, and can be used in strong acid, strong alkali, inorganic, organic salt, seawater, and other fields, such as electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment, etc.(4) Anti-magnetic bearing: Because it is non-magnetic, it does not absorb dust, which can reduce the peeling of the bearing surface, thereby reducing the running noise. Can be used in demagnetization equipment. Precision instruments and other fields.(5) Electrically insulated bearings: Due to the high resistivity, arc damage to the bearings can be avoided, and they can be used in various electrical equipment requiring insulation.(6) Vacuum bearings: Due to the unique oil-free self-lubricating properties of ceramic materials, in an ultra-high vacuum environment, it can overcome the difficulty that ordinary bearings cannot achieve lubrication. Note: For the above five types of bearings, the same set of bearings can be applied to high temperature, high speed, acid and alkali, magnetic field, and non-insulation, but due to the different material properties (please refer to the performance table of rare earth ceramic materials), customers should choose products. Choose the ceramic bearing with the most suitable material according to your application.
