Basic production process of rolling bearings

Due to the type of rolling bearing, structural type, tolerance class, technical requirements, materials and batches, the basic production process is not exactly the same.

First, the processing of the main parts of various bearings:

1. The processing of the ferrule: The processing of the inner and outer rings of the bearing varies according to the raw material or the form of the blank. The process before the machining can be divided into the following three types. The whole processing process is: bar or pipe material (Some bars need to be forged and annealed, normalized)----Car processing----heat treatment----grinding----finishing or polishing----final inspection of parts---- Anti-rust----into the warehouse----(to be combined with the package).

2. The processing of the steel ball, the processing of the steel ball also varies according to the state of the raw material, wherein the process before the frustration or the photosphere can be divided into the following three types, the process before the heat treatment, and can be further divided into the following Two kinds, the whole processing process is: bar material or wire cold punching (some bars need to be punched and annealed after cold pressing)----frustration, rough grinding, soft grinding or light ball----heat treatment- --- Hard grinding----fine grinding----finishing or grinding----final inspection group----rust prevention, packaging----into the warehouse.

3. The processing of the roller during the processing of the roller varies according to the raw materials. The process before the heat treatment can be divided into the following two types. The whole processing process is as follows: bar processing or wire cold rolling, string ring and soft grinding ----Heat treatment----string soft point----grinding outer diameter----grinding end face----finishing end face----fine grinding outer diameter----finishing outer diameter ---- Final inspection group----rust prevention, packaging----into the warehouse (to be combined with the package).

4. The processing process of the cage of the cage can be divided into the following two categories according to the design structure and raw materials:

(1) Sheet → shear → punching → stamping forming → shaping and finishing → pickling or shot peening or stringing → final inspection → rust prevention, packaging → storage (to be combined with the package).

(2) Processing of the solid cage: The processing of the solid cage varies according to the raw materials or the gross damage. The following four types of blanks can be divided into the following processing: The bar is Pipe, forgings, castings----car inner diameter, outer diameter, end face, chamfering----drilling (or pulling, boring)----pickling----final inspection---- Anti-rust, packaging----into the warehouse.

Second, the assembly process of rolling bearings:

Rolling bearing parts such as inner ring, outer ring, rolling element and cage, etc., after passing the inspection, enter the assembly workshop for assembly, the process is as follows:

Parts demagnetization, cleaning → internal and external rolling <ditch> road size grouping → combination set → check clearance → riveting cage → final inspection → demagnetization, cleaning → rust prevention, packaging → into the finished product warehouse (boxing, shipping 〉.
