SKF bearing production process

Because of the type of SKF bearing, structure, tolerance, the difference of technical requirements, material and quantity, etc, the basic production process there is a difference, too. Here is a brief introduction of production process. SKF bearing ring: SKF bearing inner ring and outer ring of the processing according to the raw materials or blank form varies, the car before the processing process can be divided into the following three, the whole process is: the bar stock or tube ( Some bar need to the forging, annealing and normalizing) — — Car processing - — Heat treatment - — Grinding - — Lapping and polishing - — Final inspection parts - — Rust - — Warehousing - — ( For sets of assembly) 。 SKF bearing ball: ball processing according to the same varies according to the status of raw materials, with sharp cutting or ball in front of the working procedure, can be divided into the following three, before the heat treatment process, and can be divided into the following two kinds, the whole process is: the bar or wire cold blunt ( After some bar cold blunt still need band and annealing) — — Sharp cutting, coarse grinding, soft grinding or ball - — Heat treatment - — Hard grind - — Fine grinding - — Lapping and polishing - — Final inspection group - — Rust and packaging - — Warehousing < to sets of assembly>. SKF bearing cage: SKF bearing retainers according to different design structure and raw material processing, can be divided into the following two categories: ( 1) Sheet metal to shear to cutting, stamping, shaping and finishing to pickling or shot peening or string light, final inspection to rust, packaging, warehousing, For sets of assembly) ( 2) SKF bearing solid cage processing: processing of solid cage, varies according to different raw materials or blank, the car before the processing can be divided into the following four kinds of blank type, the whole process is: the bar, pipe material, forging, casting, — Car inside diameter, outside diameter, end face, chamfering - — Drilling ( Or pull holes, boring) — — Pickling - — Final inspection - — Rust and packaging - — Warehousing < to sets of assembly>. Second, SKF bearing assembly process: SKF bearing parts such as inner ring and outer ring, steel ball and cage, after inspection, are assembled into the assembly workshop, the process is as follows: demagnetization, cleaning, internal and external roll < channel> way size group choose don't - and set to check the clearance, riveting cage - final inspection - demagnetization, cleaning and antirust, packaging and finished products.
