How to identify the quality of the equipment 22315 e bearing?we usually do it from the following aspects:   
In general, the brands produced by the regular manufacturers have their own special designers to design the external packaging, and arrange the production conditions of the factory for production, therefore, the packaging of the product from the line to the color block should be very clear, no ambiguity.  

Whether there is noise on 22315 e bearing
The left hand holds the inner sleeve of the 22315 e bearing, and the right hand toggle the jacket to rotate with a small amplitude, and listen to whether there is any noise during the operation of the bearing.  
Due to the backward production conditions of most counterfeit products and the complete manual workshop operation, it is inevitable that impurities such as dust and sand will be mixed into the bearing body in the production process, so there will be noise or not smooth operation when the bearing rotates. This is the key to determine whether the 22315 e bearing comes from a brand product of a formal manufacturer with strict production standards and machine operation.  

Whether the chamfering is uniform on 22315 e bearing
The so-called bearing chamfering, that is, the intersection of the horizontal and vertical surfaces, and the counterfeit bearing products, due to the limitations of production technology, are not satisfactory in these corners and edges, which we can easily identify.
