To distinguish the quality of SKF bearing, http://www.alierbearings.com/brand/skf/index4.html  we usually proceed from the following aspects:
1. Whether the outer packing is clear
 
In general, SKF bearing manufacturers are their foreign packaging design professional design, and arrange production with the conditions of the factory production, therefore, the packing of the product no matter from lines and colors should be very clear, unambiguous.
2. Whether the steel seal is clear
Every SKF bearing product has its brand name, label and so on.
Although the font is very small, SKF manufacturers products are used the steel seal technology lettering, and before without overheating treatment of words, so the font although small, but deep concave, very clear.
In general, the font of the counterfeit products is not only vague, because the printing technique is rough, the font is floating on the surface, and some can easily be wiped away by hand or the manual trace is serious.
3. Is there a noise
The left hand holds the SKF bearing body sleeve, the right hand small range of the movement of the movement of the jacket to make it rotate, listen to the bearing operation process whether there are noise.
Because most of the counterfeit product production conditions, operation, fully manual mill bearing the body in the process of production inevitably mixed into impurities, dust, sand and so on bearing rotation will be mixed ring or not smooth phenomenon.
This is the key to judging whether a product is coming from a strict production standard and is used by a formal manufacturer of machinery.
4, the surface
Whether the surface has cloudy oil stain requires special attention when buying SKF bearings.
Due to domestic antirust technology, there is still a gap with foreign advanced manufacturing countries, therefore the antirust processing was carried out on the bearing body and is easy to leave the thick oil stains, contact with the hand feeling sticky thick, and imported from abroad on the bearing of almost can't see any sign of the anti-rust oil.
According to industry insiders, especially careful people can smell a special flavor on the imported bearing, which is the smell of anti-rust oil.
5. If the chamfer is even
So-called bearing chamfer, namely horizontal plane and vertical plane junction, fake SKF bearing products because of the limitation of production technology in the area of the fringes is handled in guanzhou, as we can easily identify.
6, the packing
SKF bearing packing and outer packing
After completion of bearings in the manufacturing and the inspection, cleaning and antirust processing, then put into the inner packing, in order to achieve the waterproof, moistureproof, dustproof, shock proof, maintenance quality and precision of the bearing and the purpose of convenient use and sell.
