Ceramic bearing compared with the advantages and disadvantages of metal bearing

First, the advantages and disadvantages of ceramic bearing 1. 1, the advantages of ceramic bearing: 1, zero corrosion. Even in corrosive environment, our ceramic bearing is also still use barrier-free; Can work under strong corrosive environment. 2, temperature changing randomly. Whether high temperature suddenly, or temperature plummeted, our ceramic bearing has no effect at all; High and low temperature switch for ceramic bearing no effect. 3, is out of shape not easily. Ceramic bearing rarely because of the stress and deformation, because of the ceramic bearing elastic modulus is higher than steel. 4, long service life. Ceramic rolling ball density is lower than steel, natural light in weight, so can reduce the rotational external circle centrifugal force produced by friction, the nature of the ceramic bearing service life is longer. 1. 2, the ceramic bearing faults: 1, processing difficulties and high cost; So expensive. 2, don't impact resistance; High hardness. 3, not with the equipment heat bilges cold shrink; Temperature on the ceramic bearing no effect is both advantages and disadvantages. Second, the advantages and disadvantages of metal bearing a ceramic bearing 2. 1, the metal bearing a ceramic bearing advantages: 1, simple processing than ceramic bearing, so the cost is low. 2, more appropriate use of ceramic bearing under specific equipment. 2. 2, the metal bearing the ceramic bearing faults: 1, shorter than ceramic bearing service life. All ceramic than all steel 10 - long life 50 times, hybrid ceramic three - all steel long life About five times; Service life, ceramic bearing is much higher than the metal bearing. 2, ceramic bearing lubricant consumption. In the case of lubricating oil is thinning, ceramic bearing lubrication ability is still not less than the traditional steel bearings commonly used lubricants. 3, low rigidity. Ceramic bearing rigidity than metal bearing, ceramic materials of high elastic modulus, the rigid steel bearing 15 - larger than normal 20%. 4, compared with the metal bearing, ceramic bearing corrosion wear more. Because of its material itself is not the same, so as a direct result of corrosion and wear resistance of the ceramic bearing more excellent than the metal bearing. The use of ceramic bearing areas: can be used in very poor condition and environment, can be used in medical equipment, optical instruments, low temperature, high speed motor engineering, high speed machine tools and other fields.
