【Product Introduction】Bearing is an important mechanical basic part. Because of its excellent performance unmatched by metal bearings, high temperature resistance and super strength are leading the world in new materials..
【Features of Ceramic Bearings】1. Since ceramics are scarcely resistant to corrosion, ceramic rolling bearings are suitable for operation in harsh conditions full of corrosive media. 2. Because the density of ceramic rolling balls is lower than steel, and the weight is much lighter, the centrifugal effect of the outer ring can be reduced by 40% when rotating, and the service life is greatly extended..
【Specific Advantages of Ceramics】1. Ceramic is 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 where the temperature difference changes drastically. 2. Since the elastic modulus of ceramic is higher than that of steel, it is not easy to deform when subjected to force, so it is conducive to improving the working speed and achieving higher accuracy..
【Broad scope of application】Widely used for medical apparatus and instruments, cryogenic engineering, optical instrument, high-speed machines, high-speed electric ....
