    Sapphire bearing description


    Sapphire bearing parts high precision wear hardness 9.0 for high-end precision instruments


    Sapphire bearing is a high performance bearing made of synthetic sapphire (single crystal alumina, Al₂O₃). Sapphire is known for its extremely high hardness, excellent wear resistance and chemical stability, which can maintain excellent performance in extreme environments. Sapphire bearings are widely used in precision instruments, high-end industrial equipment and aerospace fields, and are ideal for improving equipment life and operating efficiency.



    Sapphire bearing properties


    (1) Ultra-high hardness
    The Mohs hardness of sapphire is as high as 9, second only to diamond, and the wear resistance is far greater than that of traditional metal bearings.Suitable for high load, high friction working environment, significantly extend the service life.


    (2) Corrosion resistance
    Sapphire is highly resistant to acids, bases and other chemicals and is suitable for use in corrosive environments.


    (3) High temperature resistance
    Sapphire can maintain stable performance in high temperature environments, up to 1800°C.


    (4) Low friction coefficient
    Sapphire has smooth surface and low friction coefficient, which can reduce energy loss and improve equipment operation efficiency.


    (5) High precision
    Sapphire bearing machining precision is high, suitable for high precision requirements of the application scenario.
