TIMKEN bearings how to identify the quality of knowledge - bearing

First to determine whether TIMKEN bearing outer clear: clear is whether the package, in general, are factory brand has its own professional design external packaging design, careful observation should be able to tell, and arrange production with the conditions of the factory production, so no matter from packaging lines and colors are very clear, unambiguous. Some manufacturer and there will be some special identifier, so should pay attention to and listen to the TIMKEN bearings have miscellaneous ring, hold TIMKEN bearing body, toggle coat to make it spin, listen to its hybrid ring. This is the standard production TIMKEN bearings and machine operation are factory is the biggest difference between brands. Behind most of the counterfeit products production condition, operation, fully manual mill in the process of production inevitably mixed into impurities such as sand, hidden in the TIMKEN bearing body, so makes a noise when rotating ring. See if there are muddy soil surface next, be especially careful when buying TIMKEN bearings. At present domestic antirust technology is not enough mature, so the TIMKEN bearing body the antirust processing and it is easy to leave a thick oil stains, and imported from TIMKEN bearing can hardly see the trace of anti-rust oil, if you are a connoisseur, smell the flavor of TIMKEN bearings, also can smell the rust-proof, just can't see. Finally whether chamfer is uniform, that is, on the surface of the horizontal plane and vertical junction, fake TIMKEN bearing due to the limitation of production technology, high-tech equipment, so will badly in the fringes of parts processing, is not hard to see to watch carefully. Then check the seal is the word clearly, on the TIMKEN bearing body printed with brand, label, etc. Font is very small, but is produced by the factory are mostly use seal technology, and before without overheating treatment of words, so the font although small, but concave - Deep, very clear. If it is fake product is its font is very vague, because of printing technology coarse, font float to the surface, some even can easily or hand wipe with wet cloth.
