Special Features

  • The ceramic rolling bearing is suitable to work in harsh condition of corrosive fluids, because ceramic is almost not afraid of .
  • Due to the lower density of ceramic rolling balls and much lighter weight than steel, the centrifugal effect to external race can be reduced by 40% when rotating, thus greatly extend the service life.
  • The ceramic is less affected by thermal expansion than steel, therefore, when bearing clearance is certain, it can work in a environment where temperature changes more severely.
  • The elastic modulus of ceramic is higher than steel, so ceramic is not easy to deform under stress, which can improve work speed, and achieve a higher precision.
  • Widely used for medical apparatus and instruments, cryogenic engineering, optical instrument, high-speed machines, high-speed electric machinery, printing machinery, food processing machinery, aviation, spaceflight, navigation, , chemical industry, automobile, electronics, metallurgy, electric power, textile, pumps.
