Because the type, layout, public service, skill requirements, materials and quantity of SKF bearings are different; the basic production process is also different. Let's briefly analyze the production process.
First, the processing process of commonly used SKF bearing parts:
1. The ferrule of SKF bearing: The processing of the inner and outer rings of SKF bearing varies according to the different materials or blanks; the process before machining can be divided into the following three types; the whole processing process is: bar material Or pipe material (some bars need to be cast and annealed, normalized) Car processing heat treatment grinding processing or grinding parts final inspection anti-rust storage (to be installed).
2. Balls of SKF bearings: The processing of balls is different depending on the condition of the raw materials; the process of frustration or pre-light ball; can be divided into the following three types; the process before heat treatment; Two kinds; the whole processing process is: bar or wire cold punching (some bars need to be punched and annealed after cold pressing) frustration, rough grinding, soft grinding or photosphere heat treatment hard grinding fine grinding or grinding Inspection group anti-rust, packaging into the warehouse <to be fitted installation>.
3. SKF bearing cage: SKF bearing cage processing process is different according to the layout and raw materials; can be divided into the following two categories:
.1) Sheet â†’ shear â†’ punching â†’ stamping forming â†’ shaping and finishing â†’ pickling or shot peening or stringing â†’ final inspection â†’ rust prevention, packaging â†’ storage (to be installed)
.2) Processing process of SKF bearing solid cage: processing of solid cage; different depending on raw materials or blanks; before processing, it can be divided into the following four blank types; the whole processing process is:
Bar, pipe, forgings, casting inner diameter, outer diameter, end face, chamfered hole (or pull hole, boring), pickling, final inspection, rust prevention, packaging and storage, to be installed.
Second, the installation process of SKF bearings:
SKF bearing parts such as inner ring, outer ring, steel ball and cage; after passing the inspection; enter the installation workshop for installation; the process is as follows:
Demagnetization, clearingâ†’inside and outside rolling<ditch>way scale groupingâ†’contractingâ†’viewing clearanceâ†’riveting cageâ†’final inspectionâ†’demagnetization, removalâ†’rust prevention, packagingâ†’products.

Metal Table Lamps
Metal table lamp, the whole is mainly made of metal materials, suitable for bedroom, living room, office, study and other indoor places. Modern and simple design, diverse modeling, whether placed in the home or office, can be well integrated into the environment, suitable for decoration joker. Made of metal, it doesn't look bulky, and the overall line looks very smooth. In addition to playing the role of lighting, in the case of decorative space effect, whether the light is on, or off, is a work of art.
