Technological Innovation in Coated Bearing Shells Leads Industry Development - Dafeng Mingyue Bearings Gain Market Favor

In recent years, with the increasing demand for high-performance bearing shells in industrial equipment, coated bearing shells have gradually become the focus of the industry due to their excellent performance advantages. Coated bearing shells are made by coating one or more layers of coating materials with different properties on the surface of traditional metal bearing shells. Through advanced coating technology, they effectively improve the tribological properties, wear resistance, corrosion resistance and high-temperature resistance of bearing shells, and can meet the harsh use requirements under different working conditions.

At present, coating technologies are mainly divided into four categories, each with its own characteristics. The spraying technology is to heat the coating material to a molten or semi-molten state, atomize it by high-speed air flow and then spray it onto the surface of the bearing shell to form a coating. Flame spraying and plasma spraying are common methods. Electroplating technology uses electrochemical principles to deposit metal or alloy coatings on the surface of bearing shells. Although it has good adhesion and uniformity, it has environmental pollution problems. Physical vapor deposition (PVD) converts coating materials into gaseous particles by physical methods under vacuum conditions and deposits them on the surface of bearing shells. The formed coating has high hardness, high wear resistance and good corrosion resistance, but the cost is relatively high. Chemical vapor deposition (CVD) uses gaseous reactants to react at high temperature to deposit a solid coating on the surface of the bearing shell. Its coating has good adhesion and uniformity, but the process is complex and the cost is high.

With these advanced coating technologies, coated bearing shells show many performance advantages. It can form a lubricating film between the bearing shell and the journal, reduce the direct contact between metal surfaces, reduce the friction coefficient, improve mechanical efficiency and reduce energy loss. The high hardness and strength of coating materials can effectively resist wear and prolong the service life of bearing shells. Some coating materials have good corrosion resistance, which can prevent bearing shells from being corroded in harsh environments and improve reliability and stability. Some coating materials can maintain good performance at high temperatures, reduce the temperature of bearing shells and avoid failure due to overheating. In addition, coated bearing shells can be customized according to different working conditions, and appropriate coating materials and thicknesses can be selected to meet various complex working conditions.
