The development of bearing materials
Bearing materials are components used to manufacture bearings. For the design of bearing products, an important task is the selection of bearing materials. Bearing materials are closely related to the performance of bearing products, and the choice of bearing materials directly affects the use effect of bearing products. With the development of science and technology, the bearing materials used in the manufacture of bearings have continued to develop and have made great progress.
The earlier known bearing materials include tin-lead alloys and other materials (such as carbon structural steel). With the continuous development of metallurgical science and technology, new types of bearing materials have been developed. These bearing materials include leaded chromium-nickel bearing steels, chromium-nickel bearing steels, high-carbon chromium bearing steels, and aluminum-titanium bearing alloys, etc. These bearing materials are made by adding various alloy elements to steel, and the performance of bearing materials has been further improved. With the development of bearing technology, materials such as cast polymers, celcon and uralite have been developed and applied, which have greatly improved the performance of bearing products.
In recent years, stainless steel bearing materials have emerged one after another. These stainless steel bearing materials are ferritic stainless steels and martensitic stainless steels. Compared with the traditional bearing materials, these bearing materials have better corrosion resistance, higher temperature resistance and stronger wear resistance. Many manufacturers use these bearing materials instead of the traditional bearing materials, so as to improve the performance of the bearing products and reduce their own cost.
In addition, machine-oiled bearings have also become a kind of bearing materials gradually accepted by the market. The lubrication system in the bearing can reduce friction and improve wear resistance. Compared with traditional bearings, machine-operated bearings are more energy-efficient and economical. Therefore, they are more and more used in the manufacture of bearings.
The development of bearing materials has made great progress and made very important contributions to the bearing industry. Bearing materials with good performance can effectively improve the performance of bearing products, while reducing the production cost. Therefore, it is very important to pay attention to the innovation of bearing materials in order to maintain the leading position of enterprises in the bearing industry.
