What are the bearing rings referring to?
The bearing ring refers to the seamless steel pipe which is hot-rolled or cold-rolled (cold drawn) for manufacturing common rolling bearing ring. The outer diameter of the steel pipe is 25-180mm, and the wall thickness is 3.5-20mm, which can be divided into ordinary precision and high precision.
The technical conditions for the production of bearing rings are relatively strict. The chemical composition, mechanical properties, process performance, grain size, carbide shape, depth of decarburization layer, etc. of the finished products are required to meet the requirements of relevant standards.
