Baca LagiPandangan Pantas100Cr6 Bearing Steel Tube
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 25-180mm, and the wall thickness is 3.5-20mm, which can be divided into two types: ordinary precision and higher precision. Bearing steel is used to make balls, rollers and bearing rings. Bearing works under great pressure and friction, so bearing steel is required to have high and uniform hardness, wear resistance and high elastic limit.
The requirements for the uniformity of chemical composition, the content and distribution of non-metallic inclusions, and the distribution of carbides of bearing steel are very strict. It is one of the most stringent steel grades in all steel production.

Applications of Hydraulic honed tubing
Honed tubing and SRB tubes (skived and roller burnished tubes) are mostly used as cylinder tube, such as hydraulic cylinder tube and pneumatic cylinder tubing, which are widely used for manufacturing and repairing hydraulic cylinders and pneumatic cylinders. As honed tube has very accuracy dimension tolerance and good surface smoothness, so this product is also used in applications where precision dimension or high smooth surface is need.
