Bearing Steel Tube

Instruction

Products Discription
What is tube bearings? What is bearing steel tube ? Bearing steel pipe refers to hot-rolled or cold-rolled (cold-drawn) seamless steel pipe for the manufacture of ordinary rolling bearing rings. The outer diameter of the steel pipe is 25-194 mm, and the wall thickness is 3.5-30 mm. There are two kinds of ordinary precision and high precision. Bearing steel is the steel used to make balls, rollers, and bearing rings. Bearings are subjected to great pressure and friction during work, so bearing steel is required to have high and uniform hardness and wear resistance, as well as high elastic limit. The requirements for the uniformity of the chemical composition of the bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict, and it is one of the most stringent steel grades in all steel production.
