Talking about how to distinguish the quality of bearings
Bearings are a kind of parts used in every mechanical equipment. The quality of the bearing directly affects the working efficiency of the mechanical equipment. The existence of the bearing can reduce the friction coefficient of the internal parts of the machine and ensure the accuracy of rotation. The development of bearings and the replacement of bearings are also very obvious. Now the quality of bearings is getting better and better, so today I will talk about how bearings can distinguish quality.
1. Whether the outer packaging is clear: The brands produced by regular manufacturers have their own dedicated designers to design the outer packaging, and arrange for the production of factories that pass the production conditions. Therefore, the product packaging should be very good from lines to color blocks. Clear and unambiguous.
2. Whether the steel stamp is clear: each bearing product will have its brand name, label, etc. printed on the bearing product body. Although the font is very small, the products produced by regular manufacturers are printed with steel stamping technology, and they are pressed before heat treatment. Therefore, although the font is small, it is deeply concave and very clear.
3. Whether there is noisy noise: hold the inner sleeve of the bearing with your left hand, and slightly reciprocate the sleeve with your right hand to make it rotate, and listen for noisy noise during the operation of the bearing.
4. Whether the chamfer is uniform: the so-called chamfer of the bearing is the junction of the horizontal and vertical planes. Due to the limitation of production technology, the counterfeit bearing products are not handled satisfactorily at these corners and corners. We can easily distinguish.
The quality of the bearing is basically identified in the above four points. The raw material of the bearing is also very important, which affects the service life of the bearing. Different bearings have different ranges of use, such as deep groove ball bearings, roller bearings and so on.
