Bimetal boundary lubricated bearings are a type of high-performance bearing that combines the strength and wear resistance of metal materials with the lubricating properties of lubrication materials, achieving excellent boundary lubrication effects. The design of these bearings thoroughly considers the choice of materials, bonding strength, and load-bearing capacity, enabling stable operation under various harsh conditions.

Bimetal composite bearings use high-quality low-carbon steel as the substrate, with a surface sintered with a low-friction copper alloy to form the wear-resistant layer of the bearing. This structure not only ensures the bearing’s strength but also endows the bearing surface with excellent wear resistance and lubricity. The copper alloy surface can be processed with various types of oil grooves, oil holes, and oil pockets according to operational needs, enhancing the bearing’s lubrication performance and making it particularly suitable for situations where continuous oiling is impossible or challenging.

Through a process of secondary sintering and extrusion, a robust bond is formed between the substrate and the wear-resistant layer of the bimetal composite bearing, ensuring good bonding strength and optimal load-bearing capacity. This allows the bearing to maintain stable performance even under heavy loads and high impacts.

In terms of application areas, bimetal boundary lubricated bearings are widely used due to their excellent performance. In the field of construction machinery, they are primarily used in components such as the support wheel bushings, track wheel bushings, and tension wheel bushings of the chassis walking mechanism, capable of withstanding high impacts and loads under complex road surfaces and harsh environments. In the automotive industry, these bearings are extensively applied in key components like the balance shaft bushing, steel pin bushing, steering knuckle kingpin bushing, connecting rod bushing, valve rocker arm bushing, camshaft bushing, differential bushing, and gearbox bushing, ensuring stability and safety under various conditions. Additionally, they are used in components like the side plates of plunger pumps and gear pumps to meet the high wear resistance and lubrication requirements of these parts.

Overall, bimetal boundary lubricated bearings, with their unique structural design and superior performance characteristics, play a crucial role in various mechanical and engineering applications, providing strong support for industrial development.
