Bearing steel pipe refers to hot-rolled or cold-rolled (cold-drawn) seamless steel pipe, used for manufacturing ordinary rolling bearing rings. The outer diameter of the steel pipe is 25-180 mm, and the wall thickness is 3.5-20 mm. It is divided into two types: ordinary precision and higher precision.
In 1976, the International Organization for Standardization incorporated some common bearing steel grades into international standards and divided bearing steel into four categories, including fully hardenable, surface hardened, stainless and high-temperature bearing steel, with a total of 17 steel grades. Among them, high-carbon chromium bearing steel GCr15 is the most produced bearing steel in the world, with a carbon content Wc of about 1% and a chromium content Wcr of about 1.5%, accounting for more than 80% of the world's total bearing steel production.
Bearing steel is the steel used to make balls, rollers and bearing rings. Bearing steel has high and uniform hardness and wear resistance, as well as high elastic limit. The requirements for the uniformity of the chemical composition of bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict. It is one of the most stringent steel types in all steel production. Bearing steel seamless pipes also have some other advantages and characteristics.
First of all, bearing steel seamless pipes have good corrosion resistance and good anti-rust properties, and can be used in various corrosive environments to effectively protect bearing components from damage. This makes bearing steel seamless pipes widely used in highly corrosive environments, such as chemical industry, marine engineering and other fields.
Secondly, the bearing steel seamless pipe has good processing performance and strong fatigue resistance. After heat treatment, it should have high hardness or a hardness that can meet the performance requirements of the bearing, high wear resistance, low friction coefficient, and high elastic limit. Good impact toughness and fracture toughness, good dimensional stability, good cold and hot processing properties. Disadvantages: It is easy to deform due to temperature changes. It can be processed into various complex geometric shapes and structural forms through various processing methods, such as turning, milling, drilling, etc., to meet various different use needs. In addition, bearing steel seamless pipes can also undergo processing processes such as heat treatment and surface treatment to further enhance their performance and lifespan.
Finally, during the production process, bearing steel seamless pipes can achieve highly automated and intelligent production, improving production efficiency and product quality. At the same time, modern bearing steel seamless pipe manufacturing technology also focuses on environmental protection and sustainable development, minimizing the impact on the environment and resource consumption, and achieving green manufacturing and sustainable development.
In summary, bearing steel seamless pipes are widely used in machinery manufacturing, transportation, energy equipment, aerospace, etc. due to their strong wear resistance, excellent fatigue resistance, good corrosion resistance, good processing performance, and strong adaptability. It has been widely used in various fields and provided strong support for the development of various industries. In the future, with the continuous advancement of science and technology and the increase in industrial demand, bearing steel seamless pipes will continue to play an important role and bring more convenience and benefits to human production and life.
