Comparison of the properties of four bearing materials for ceramic bearings: ordinary bearing steel AISI52100 (GCr15), stainless steel AISI440 (9Cr18), silicon nitride (Si3N4) and zirconia (ZrO2). Ceramic bearings are an important mechanical foundation. Excellent performance unmatched by metal bearings, high temperature resistance, super strength, etc. take the lead in the world of new materials.
Ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, anti-magnetism and electric insulation, oil-free self-lubrication, high speed and so on. It can be used in extremely harsh environments and special working conditions, and can be widely used in aviation, aerospace, navigation, petroleum, chemical industry, automobiles, electronic equipment, metallurgy, electric power, textiles, pumps, medical equipment, scientific research and national defense military and other fields. High-tech products with new material application.
