Zirocnia Ceramics:
Ordinary bearing steel AISI52100 (GCr15), stainless steel AISI440 (9Cr18), Silicon Nitride (Si3N4) and zirconia (ZrO2) four bearing material performance comparison, ceramic bearings as an important mechanical basic parts, due to its metal bearing Unmatched performance, high temperature resistance, super strength, etc. 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. First, since ceramics are hardly corrosive, ceramic rolling bearings are suitable for operation under harsh conditions filled with corrosive media.
Second, since the density of the ceramic rolling ball is lower than that of the steel, the weight is much lighter, so the centrifugal effect of the outer ring can be reduced by 40% when rotating, and the service life is greatly prolonged.
Third, ceramics are less affected by thermal expansion and contraction than steel. Therefore, when the clearance of the bearing is constant, the bearing can be allowed to work in an environment where the temperature difference changes drastically.
Fourth, since the modulus of elasticity of ceramics is higher than that of steel, it is not easily deformed when subjected to force, so it is advantageous to increase the working speed and achieve higher precision.
