Common Identification Methods Of Bearings

Bearing is an important part of modern mechanical equipment.Its main function is to support the mechanical rotating body, reduce the friction coefficient in the process of movement, and ensure the accuracy of rotation.It is not too much to call the bearing the joint of the car. In a car, not only the wheel needs to use the bearing, but all the rotating machine parts need the participation of the bearing. It is a very insignificant but important thing in the transmission system.Because of the large workload, its wear degree is relatively high, so the replacement of bearings is more common in automobile maintenance.Bearing products are good and bad, and many fake and shoddy products are mixed with them. In order to have a certain understanding of the characteristics of bearings, BMB Bearings introduces the commonly used identification methods of bearings.
1. Whether the outer packaging is clear
Under normal circumstances, the factory brand has its own special designers for external packaging design, and arrange production conditions pass the factory production, so the packaging from lines to color blocks are very clear, no ambiguity.

2. Whether the steel characters are clear
Brand words and labels will be printed on the bearing body.The font is very small, but the factory produces most of the use of steel printing technology, and in the heat treatment before the word, so although the font is small, but deep concave, very clear.And the font of counterfeit products is not only fuzzy, because the printing technology is rough, the font floats on the surface, some even easy can be wiped away with the hand.
3. Whether there is noise
The left hand holds the bearing body sleeve, and the right hand stirs the coat to rotate it and listen to whether there is any noise.Due to the backward production conditions of most counterfeit products, completely manual workshop operation, in the production process will inevitably be mixed with sand and other impurities, hidden in the bearing body, so it will emit noise when rotating.It is and strictly enforced
The biggest difference between manufacturing standard and machine-operated factory brands.
4. Whether there are muddy oil stains on the surface
This should be paid special attention to when buying bearings.When carrying out antirust treatment on the bearing body, it is easy to leave a thick oil mark. It is sticky and thick in the hand. It is particularly careful that experts say that imported bearings smell of a kind of taste, which must be under the antirust oil, but they can not see it.
5. Whether the chamfering is uniform
The so-called bearing chamfer, that is, the intersection of the horizontal plane and the vertical plane, the counterfeit bearing is unsatisfactory in the parts of the edges and corners due to the limitations of production technology.
