Bearing the distinguish method of imported cars - bearing knowledge

Auto bearing generally use imported bearings, bearings imported cars are still very good, quality is very good, domestic auto bearing, relatively cheaper, now imports of bearing a lot of product quality is good, NSK imported bearings, FAG bearings, such as and imported SKF bearing for auto bearing. As the domestic car ownership continues to rise, the use of auto parts and automotive supplies demand is also increasing, however, the domestic large and small parts and supplies management store multiple and complex, the goods the good and bad are intermingled, mixed with a lot of fake and inferior products, thereby causing loss to the owner's, serious can even lead to personnel casualties. In order to let the owner of each related accessories and supplies are factory brand characteristics have a certain understanding, to show the owner friends for all sorts of types, to identify the major car brand accessories. Called the bearing car joint point. On a car, not only is it four legs - — — Wheels need to use the bearing, the fact will involve the participation of bearing rotating machine parts, but it's a very humble in the transmission system is of great things. Because workload is big, its wear is high also, so change the bearing is more common things in vehicle maintenance and repair. Walking in the auto parts market, found operating various brands of bearing store a dime a dozen, how they sell bearing quality, however, whether such as are factory brand is marked on the package? This doubt about wandering around in the heart of every car owner many times. Below to introduce you to several common methods to distinguish the quality of bearing: the outer packing is clear: in general, are factory brand has its own special foreign packaging designers design, and arrange production with the conditions of the factory production, so the packaging is very clear, from the lines to the colors. Seal character is clear: on the 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 deep concave, very clear. And counterfeit products font instead of fuzzy, because of printing technology coarse, font float to the surface, in some cases can be easily erased by hand. Whether there are miscellaneous ring: the bearing body with his left hand, right hand toggle coat to make it spin, listen to its hybrid ring. Due to the backward production conditions most of the counterfeit products, fully manual mill operation, in the process of production inevitably mixed into the sand kind of impurity, hidden in the bearing body, so makes a noise when rotating ring. This is and strict production standards, and use machine operation are factory is the biggest difference between brands. If there is a muddy surface oil stains: this should pay special attention to when to buy imported bearings. Due to the current domestic antirust technology is not particularly home, so the antirust processing was carried out on the bearing body and is easy to leave the thick oil stains, holding the thick thick, and imported from abroad can hardly see the trace of anti-rust oil bearing, is particularly careful expert said imported bearing smell a smell, must be under the anti-rust oil, just can't see. Chamfer whether uniform: so-called bearing chamfer, namely horizontal plane and vertical plane junction, counterfeit bearings because of the limitation of production technology in the area of the fringes is handled.
