Introduction
Tin-based bearing alloy dingesare an important part of modern industrial ball bearing and roller bearing components. Compared with other bearing materials, tin-based bearing alloys have superior corrosion resistance, higher temperature fatigue life, good wear resistance and thermal conductivity, good machinability and manufacturing adaptability. With the continuous development of industrialization, the demand for tin-based bearing alloys is increasing.
Background
Tin-based bearing alloy dings are mainly used for steel ball bearings, roller bearings and bearing accessories for various motors, automobiles and motorcycles. The tungsten-based bearing alloy dings are an important part of the modern industrial ball bearing and roller bearing components. In comparison with other bearing materials, they have superior corrosion resistance, higher temperature fatigue life, go od wear-resistance and thermal conductivity, good machinability and manufacturing adaptability. Tin bearing alloy dinges are superior in terms of mechanical properties, low-friction, and anti-vibration temperatures.
Ingredients
The tin-based bearing alloy dinges are composed of copper (78.0 - 84.0%), lead (12.0 - 15.0%), tin (2.8 - 5.0%), nickel (0.1 - 0.7%), phosphorus (0.17 - 0.23), bismuth (1.8 - 2.0%), arsenic (0.2 - 0.7%), silicon (0.2 - 0.7%), zinc (0 - 0.8%) and other small amounts of precious metals.
Process of Manufacture
The process of manufacture for tin-based bearing alloy dinges can be divided into five stages. First, the ingredients are mixed in with a set ratio in a furnace. The furnace temperature is set to 800 to 850℃ and they are smelted under oxidation and reduction respectively. The second step is to cast the melted alloy to a dinge with the size and shape required. After the casting, the dinge is allowed to cool down gradually. The third step is to agitate the dinge after its cooling. During the fourth step, the dinge is machined according to the required dimensions and subjected to heat treatments for grain refinement and improvement of mechanical properties. The fifth step is to perform various surface treatments, such as shot peening, gas nitriding, carburizing and so on, for the surface protection and for extending the bearing life.
Performance
The performance of the tin-based bearing alloy dinges depends on the quality of the components and their assembly, as well as their design and usability. Tin-based bearing alloys have excellent anti-vibration, anti-wear and anti-corrode properties even at higher temperatures. They also have low friction coefficients and high fatigue strength, making them suitable for precision working machines and bearings that are required to function properly at extreme temperatures. Tin-based bearing alloys have an excellent nitrogen absorption rate and stability. They have a very high coefficient of thermal conductivity and a very high thermal expansion rate. They are more wear resistant and resistant to corrosion than other bearing alloys.
Conclusion
In conclusion, the tin-based bearing alloy dinges are a key component for motors, cars and other industries. They are made of various metals, including copper, lead, tin, nickel, phosphorus ,bismuth and arsenic. Tin-based bearing alloy dinges have good corrosion resistance, higher temperature fatigue life, good wear resistance and thermal conductivity, good machinability and manufacturing adaptability. They also have excellent anti-vibration and low friction coefficients, and a high fatigue strength. With the continuous development of industrialization, tin-based bearing alloy dinges are increasingly in demand.
