Belts and bearings is an important part of mechanical equipment

Belts and bearings is an important part of modern mechanical equipment.Its main function is to support the mechanical rotating body, reduce its friction coefficient in the process of motion, and ensure its rotation accuracy. 
How to identify the quality of belts and bearings?
Whether the chamfering is even  
The so-called belts and bearings chamfering, that is, the intersection of the horizontal and vertical surface, counterfeit bearing products due to the limitations of production technology, in these corners of the parts of the processing is not satisfactory, which we can easily identify.  

Whether the steel seal is clear  
Each belts and bearings product will be printed with its brand words, labels and so on on the bearing product body.  Although the font is very small, but the regular manufacturers of products are using steel printing technology printing, and in the process of pressing before overheating, so the font although small, but concave deep, very clear.  
But usually, the font of counterfeit products is not only fuzzy, because the printing technology is rough, the font is floating on the surface, some can even be easily wiped by hand or manual traces are serious.  
Is there any noise   

The left hand holds the belts and bearings body sleeve, and the right hand reciprocates the coat with a small amplitude to make it rotate. Listen to whether there is any noise in the process of bearing operation.  
Due to the backward production conditions of most counterfeit products, completely manual workshop operation, in the production process, the belts and bearings body will inevitably be mixed with dust, sand and other impurities, so when the bearing rotates, there will be noise or operation is not smooth.  
This point is the key to determine whether the product is manufactured by a reputable manufacturer with strict manufacturing standards and operated by machines.
