As an important mechanical basic component, ceramic bearings have great performance that metal bearings can not match. High temperature weight, super strength, etc. take the lead on this planet of new materials.
Primary, because ceramics are almost not afraid of rust, ceramic rolling bearings are well suited for operation under harsh conditions full of corrosive media.
Second, because the density of the ceramic rolling ball is less than that of steel, plus the weight is much lighter in taste, the centrifugal effect belonging to the outer ring during rotation is often reduced by 40%, as well as the service life is enormously extended.
Third, ceramics are less suffering from thermal expansion and contraction in comparison with steel, so when this bearing gap is constant, the bearing can be allowed to be effective in an environment the place that the temperature difference changes more drastically.
Fourth, since the elastic modulus of ceramic is higher than that of steel, it is not easy to deform when put through force, so it is beneficial to increase the working speed and achieve higher accuracy.
(1) High-speed impact: It has the benefits of cold resistance, small induce elasticity, high pressure challenge, poor thermal conductivity, light weight, and small friction coefficient. It could be applied to high-speed spindles from 12, 000 rpm in order to 75, 000 rpm yet others In high-precision equipment;
(2) Excessive temperature resistant bearing: The material itself is immune to high temperature associated with 1200℃, and it will be self-lubricating. The use temperature will be between 100℃ and 800℃ without expansion caused by temperature difference. It may be used in furnaces, plastics, steel and various high-temperature equipment;
(3) Corrosion-resistant bearings: The material itself has corrosion-resistant properties and can be utilized in fields such when strong acid, strong alkali, inorganic, healthy salt, seawater, etc.,like: electroplating equipment, electronic machines, chemical machinery, shipbuilding, professional medical equipment, etc..
(4) Antimagnetic impact: Because it is non-magnetic, it not absorb dust, which can reduce the peeling in the bearing surface, thereby lessening the operating noise. Works extremely well in demagnetization equipment. Precision instruments and other fields.
(5) Electrically insulated bearings: Because of their high resistivity, they can avoid arc destruction of the bearings and can be utilized in various electrical machines requiring insulation.
(6) Hoover bearings: Due to that unique oil-free and self-lubricating traits of ceramic materials, it may overcome the problem of which ordinary bearings cannot obtain lubrication in an ultra-high void environment. Note: For the above five varieties of bearings, the same pair of bearings can be put on high temperature, high speed, acid and alkali, magnet field, non-insulation, but on account of different material properties (please talk about the performance table regarding rare earth ceramic materials), and so when customers choose products and solutions, According to your application, choose the ceramic bearing considering the most suitable material.
