Introduction Bearing steel pipe is a kind of hot-rolled or cold-rolled (cold-drawn) seamless steel tube. It is used for producing general antifriction bearing ferrule. The outside diameter is 25 mm to 180 mm and the thickness is between3.5 to 20 mm. we mainly provide general precision and high precision bearing steel tubes. It withstands great pressure and friction force, so bearing steel pipe must have high and uniform hardness and abrasive resistance and high elastic limit. There are strict requirements for bearing pipe, such as the uniformity of chemical composition, non-metallic inclusion content and distribution, distribution of carbides and other requirements.

Applications of Bearing Steel Tube Bearing steel pipe can be used for producing kinds of bearing ferules, rollers and steel balls applied in combustion engine, electric motor car, automobile, tractor, lathe, rolling machine, drilling machine, mining machinery, general machinery, as well as high-speed rotated mechanical transmission bearing.

• JST bearing steel pipe adopts foreign advanced bearing tube annealing technology to control atmosphere protection, temperature and cooling rate. Vacuum seal and nitrogen protection can make our bearing steel tubes can not be oxidized and deform in the annealing. We can control the temperature conveniently and freely. The whole process is under video monitoring.
• Our bearing steel pipes have excellent overall performance and good cutting performance after ball annealing. After quenching and tempering, they acquire high and uniform hardness, high wear resistance and contact fatigue strength, and high thermal processing performance.

Jiangyin Changjiang Steel Tube Making Factory is a leading supplier and exporter of bearing steel tubes in China. We also manufacture structure pipe, fluid pipe, high pressure boiler pipe, API pipe, marine pipe, alloy pipe, tubing, casing, line pipe, etc. Our company sets up a steel tube technology R & D center with advanced pipe testing equipment. Through strict testing process, we are able to produce high quality bearing steel pipes for customers. JST bearing steel tubes have been exported to the Middle East, CIS, Southeast Asia, Africa, South America, North America, Europe, Australia and many other countries and regions.
