  Shield machine is a tunnel construction equipment that integrates machinery, electricity, hydraulics, optics, mechanics, pneumatics, sensing, information, and guidance, and can complete construction processes such as excavation, support, and slag removal and perform continuous operation in factory-like assembly lines. The shield machine is known as the "king of construction machinery", and it is a major key equipment to measure the level of a country's equipment manufacturing level. With the comprehensive deployment of shield tunneling construction of urban subways, railway tunnels, highway tunnels, water conservancy engineering, municipal gas pipeline engineering, sewage pipeline engineering, heating and cooling pipeline engineering, and cable pipeline engineering in China, the total market demand for shield machines shows a rapid growth trend, which also brings a broad market to shield machine bearings. The cutter head is a key component of the shield machine and play...

Commonly used bearing cages are divided into metal cages and non-metal cages according to material types, as well as composite material cages. According to the material, the bearing cage mainly includes low carbon steel stainless steel cage, bakelite/nylon cage, brass/bronze/aluminum alloy cage, etc. Bearing cages for special purposes should also meet the requirements of special working conditions, such as high temperature resistance, corrosion resistance, self-lubricating or non-magnetic, etc. Steel cage material Due to its high strength, good toughness, and easy processing, steel cage materials are widely used in rolling bearings. It is often made of 08 and 10 high-quality carbon steel sheets by cold stamping. Commonly used steel cage materials are 20, 30, 45, 0Cr18Ni9, 1Cr18Ni9Ti, 40CrNiMo, ML15, ML20, etc. Non-ferrous metal cage material Non-ferrous metals have their special properties. For example, aluminum alloys have the characteristics of low density, good thermal conductivity ...
