Austria; Spherical roller bearing origin: Malaysia (usually small), Sweden (large model), Germany (large model); Needle roller bearing origin: Germany.

8 After the bearing is unpacked, the large bearing is usually sealed in a plastic bag, and the small bearing is a plastic wrapper. There is a layer of grease on the bearing, and the real bearing has traveled outside the country clearly, without rust and pitting.

Place of production Country of production Production category.

11 Sweden – spherical ball bearings Spherical roller bearings.

15 UK 3 – Spherical roller bearings.

15 Britannica 3 – Spherical roller bearings.

18 Germany – cylindrical roller bearings, tapered roller bearings.

21 France 0 – deep groove ball bearings.

23 Austria 6 – angular contact ball bearings.

28 Australia – Angular contact ball bearings.

29 Italy angular contact ball bearings, thrust bearings, spherical bearings.

56 Malaysia – Deep groove ball bearings Spherical roller bearings.

72 USA 6 – Angular Contact Ball Bearings.

With the above bearing knowledge they can be distinguished from the surface, if it is not only to find their first business, the best way is to buy directly from the first business.

More than 95% of fakes on the market... Especially the shops opened by people in the area where Pan Jinlian and Wuda sold baked cakes.

Look at the place of origin, the origin of ball bearings: Malaysia, Italy, France, the United States (American bearings are generally only used in the United States); Origin of short cylindrical bearings:

Germany; Angular contact bearing origin: Austria; Spherical roller bearing origin: Malaysia (generally small), Jinchong Sweden (large model Xiang Yan), Germany (large model); Needle roller bearing origin:

Germany; 8. After the bearing is unpacked, the large bearing is generally sealed plastic bag, and the small bearing is plastic wrapping paper. There is a layer of grease on the bearing, and the real bearing has a bright appearance, no rust and pitting.
