White Full ZrO2 6*13*3.5mm Miniature 686 Ceramic ball bearing

The performance comparison of ordinary bearing steel AISI52100 (GCr15), stainless steel AISI440 (9Cr18), silicon nitride (Si3N4) and zirconia (ZrO2) four kinds of bearing materials, ceramic bearing as an important mechanical basic part, because of its metal-bearing Unmatched excellent performance, high-temperature resistance, super strength, etc. dominate the world of new materials
Ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, anti-magnetic and electrical insulation, oil-free self-lubrication, and high speed. It can be used in extremely harsh environments and special working conditions. It can be widely used in aviation, aerospace, navigation, petroleum, chemical, automotive, electronic equipment, metallurgy, electric power, textiles, pumps, medical equipment, scientific research, national defence and military fields. High-tech products for the application of new materials.
The rings and rolling elements of ceramic bearings are made of all-ceramic materials, including zirconia (ZrO2), silicon nitride (Si3N4) and silicon carbide (Sic). The retainer is made of polytetrafluoroethylene, nylon 66, polyetherimide, zirconia, silicon nitride, stainless steel or special aviation aluminium, thereby expanding the application range of ceramic bearings.
