Common 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, why ceramic stronger than steel ?Because of its excellent performance that metal bearings can't match, high temperature resistance and super strength are the only ones in the world of new materials. In the past ten years, it has been widely used in various fields of national economy and people's livelihood.
Since ceramics are hardly corrosive, ceramic rolling bearings are suitable for operation under the harsh conditions of corrosive media.So why ceramic stronger than steel?
The sencond reason of ceramic stronger than steel : 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.
The third reason of ceramic stronger than steel : The influence of thermal expansion and contraction of the ceramic is smaller than that of the 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.
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.
Why ceramic stronger than steel?Because ceramic bearings have high temperature resistance, cold resistance, wear resistance, corrosion resistance, magnetic insulation, oil-free self-lubrication, high speed and other characteristics. Why ceramic stronger than steel? It can be used in extremely harsh environments and special working conditions.Why ceramic stronger than steel? It can be widely used in aviation, aerospace, marine, petroleum, chemical, automotive, electronic equipment, metallurgy, electric power, textile, pump, medical equipment, scientific research and national defense military. High-tech products for new materials applications.
