All ceramic bearings produced by Shanghai Yuwei are treasures

Published on: April 2, 2018 10:02:59 Views: 1992

Shanghai Yuwei Bearing Co., Ltd Productive All ceramic bearing What are the characteristics?

First of all, Shanghai Yuwei produced All ceramic bearing There are five advantages:

1、 Yuwei ceramics The weight of the bearing is light

Yuwei Ceramic bearing It is much lighter than ordinary bearing in weight Ceramic bearing Its weight is only 30% to 40% of that of the same type of ordinary bearing. Yuwei ceramics The advantage of low bearing weight is that the centrifugal force on the outer ring of the bearing itself is reduced when the bearing rotates, as well as the increase and slip of the moving body load caused by the centrifugal force, so as to prolong the service life of the bearing.

2. Yuwei Ceramic bearing It has good stability

Yuwei Ceramic bearing It is made of ceramics, and the physical and chemical stability of ceramics is high, especially in the performance of corrosion resistance. It can be operated in extremely harsh conditions with high acid-base concentration. At the same time, the ceramic's heat resistance, cold resistance, insulation and magnetoelectric resistance are also excellent.

3. Yuwei Ceramic bearing The coefficient of thermal expansion is small

The heat and cold resistance of Yuwei ceramic bearing is also reflected in its smaller expansion and contraction when it encounters cold and heat. Especially, compared with ordinary steel, its thermal expansion coefficient is 20% lower than that of bearing steel. Therefore, under the condition of certain bearing clearance, ceramic bearing can work under the condition of relatively long temperature difference change.

4、 Yuwei ceramics High elastic modulus

The elastic modulus of Yuwei ceramic bearing is higher than that of ordinary bearing. The elastic modulus of ceramic is 1.5 times of that of bearing steel, and the hardness is 1 times of that of bearing steel. Therefore, it has more advantages in rigidity and wear resistance, which is conducive to improving the speed and accuracy of work, and the life of bearing itself has been effectively extended.

Secondly, Yuwei Ceramic bearing There are also the following main features

Yuwei Ceramic bearing The performance price ratio of the bearing is far better than that of the all steel bearing. The service life of the bearing can be increased by more than 3 times than that of the bearing used now. It can save a lot of maintenance time, reduce the scrap rate and reduce the stock of bearing spare parts.

Compared with the performance of bearing steel, the dead weight is 30%? 40% of that of bearing steel, which can reduce the increase and slip of moving body load caused by centrifugal force. Due to high wear resistance and rotating speed 1.3-1.5 times of bearing steel, the surface damage of raceway caused by high speed rotation can be reduced. The elastic modulus of bearing is 1.5 times higher than that of steel bearing. It can reduce the deformation caused by high load. The hardness is twice of the bearing steel, which can reduce the wear. The compression resistance of steel bearing is 5 times. The coefficient of thermal expansion of steel bearing is less than 20%. The friction coefficient is less than 30% of bearing steel, which can reduce the heat generated by friction and reduce the bearing premature spalling failure caused by high temperature. Tensile, bending and metal equivalent imported bearings

Thirdly, the ceramic bearing produced by Shanghai yumicro bearing has the following main advantages

1. Because ceramics are almost not afraid of corrosion, ceramic rolling bearings are suitable for operation under the harsh conditions full of corrosive media.

2. Because the density of ceramic rolling ball is lower than that of steel and its weight is much lighter, the centrifugal effect on the outer ring can be reduced by 40% during rotation, thus the service life is greatly prolonged.

3. The influence of thermal expansion and cold contraction on yumicro ceramic is smaller than that of steel. Therefore, when the bearing clearance is fixed, the bearing can be allowed to work in the environment with severe temperature difference.

4. Because the modulus of elasticity of yumicro ceramic is higher than that of steel, it is not easy to deform under stress, so it is beneficial to improve the working speed and achieve higher precision.

Fourth: what are the main uses of all ceramic bearings produced by Shanghai Yuwei

 Shanghai Yuwei Bearing Co., Ltd

Yuwei ceramic bearing has the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, magnetoelectric insulation, oil-free self lubrication, high speed and so on. It can be widely used in aviation, aerospace, navigation, petroleum, chemical industry, automobile, electronic equipment, metallurgy, electric power, textile, pumps, medical equipment, scientific research, national defense and military and other fields. It is a high-tech product for the application of new materials. 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 retainer is made of polytetrafluoroethylene, nylon 66, polyether acylamine, zirconia, silicon nitride, stainless steel or special aviation aluminum, so as to expand the application of ceramic bearings.

Fifth, the application fields of Yuwei ceramic bearing medical apparatus and instruments Low temperature engineering optical instrument High speed machine tools, high-speed motors, printing machinery, food processing machinery.
