Summary of commonly used methods to identify FAG bearing
The FAG bearing called car joint a little too. In a car, not just its four legs and wheels need to use FAG bearings in machinery parts, usually change without FAG bearing, it is the transmission system is very inconspicuous but serious relationship between devices. Because of large amount of mission, its wear degree is high, so the change of FAG bearings are more often seen in car repair work. Walking in the auto parts market, found the FAG bearing store operating various brands of uncountable refers to calculate, but they sell FAG bearing quality how, whether as marked on the packaging is the brand? This question about in each car owner heart many times. The common way to introduce you several distinguished FAG bearing quality:
The outer packing is clear: under normal circumstances, are factory brand has its own specialized design personnel external packaging design and layout, production conditions through the workshop manufacturing production, so the packaging from the line to the blocks of color are very clear, unambiguous. (local brand accessories packaging and special joint design, in order to protect the intellectual property of my this will continue to specific introduction in the future content).
The word symbol is clear: in FAG bearing brand name will be printed on the label words, etc.. The font is very small, but is produced mostly by stamping skills, and not through the heat treatment is carried out before the embossing, so the font is small, but the concave too deep, very clear. And counterfeit products not only because the printer font trance, skills and coarse, font facade, some even simply can be wiped off by hand.
Whether there are miscellaneous ring: the left hand holding the FAG body bearing sets, the right hand toggle coat makes the torsion, listening to the noise can have. Because of the large local counterfeit production premise behind, entirely hand workshop type operations, in the production process will inevitably impurity into the sand type, hidden in the FAG bearing the body, so in turn when they announced the hybrid ring. This is the strict implementation of norms, and production and between machine operation is the biggest difference of brand.
The appearance of whether there are cloudy oil: it should pay special attention to in the purchase of FAG bearings. Because the current domestic antirust skills are not special at home, so the antirust processing on FAG bearing body is easy to leave a thick layer of grease, get in the hands of sticky stiff, and the foreign original FAG bearings can hardly see the traces of rust preventive oil, is special attentive all FAG bearings smell there is a flavor, is the anti rust oil, just do not see it.
Chamfer can mean: the so-called FAG bearing chamfer, which is horizontal and the vertical surface replacement, FAG bearing counterfeit because production skills in dealing with these restrictions, the corners of the site satisfactorily.
