A:The basic process for the bearing manufacturing is as follows: testing raw material, cutting steel tubes, hardening, machine processing, surface grinding, super finishing grinding, cleaning the parts, assembling, cleaning, oil coating, cover pressing, quality testing, packing, shipping. (Due to the types of rolling bearing, structural type, tolerance class, technical requirement, material and batch, the basic production process is not exactly the same.) During the bearing production process, the most critical steps are forging, heat treatment and grinding.
