Bearings are one of the indispensable parts of modern industry, and the requirements for their materials are getting higher and higher. High-precision ceramic bearings have excellent performance and can replace metal materials. The following Pintejin zirconia ceramic machining factory will introduce the advantages of high-precision ceramic bearings. with the main use.
Comparison of the performance of four bearing materials: ordinary bearing steel, stainless steel, silicon nitride and zirconia, ceramic bearings are an important mechanical foundation.
Because high-precision ceramic bearings have excellent performance unmatched by metal bearings, high temperature resistance and high strength are leading the world in new materials. In the past ten years, it has been widely used in various fields of national economy and people’s livelihood.
Advantages of high-precision ceramic bearings:
- 1. Since ceramics are almost not afraid of corrosion, ceramic rolling bearings are suitable for operation in harsh conditions full of corrosive media.
- 2. Since the density of the ceramic rolling ball is lower than that of steel and the weight is much lighter, the centrifugal effect of the outer ring can be reduced by 40% during rotation, and the service life is greatly extended.
- 3. Ceramics are less affected by thermal expansion and contraction than steel, so when the bearing clearance is constant, the bearing can be allowed to work in an environment with severe temperature difference.
- 4. Since the elastic modulus of ceramics is higher than that of steel, it is not easy to deform when subjected to force, so it is beneficial to improve the working speed and achieve higher precision.
The main uses of high-precision ceramic bearings:
Ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, anti-magnetic and electrical insulation, oil-free self-lubrication, and high speed. It can be used in extremely harsh environments and special working conditions, and can be widely used in aviation, aerospace, navigation, petroleum, chemical, automotive, electronic equipment, metallurgy, electric power, textiles, pumps, medical equipment, scientific research and defense and military fields. High-tech products for new material applications.
