What are the methods for identifying bearings?

There are many types of bearings, which are key components that mainly support flexible operation. However, there are many fake products nowadays, and if we are not careful, we will be deceived and buy inferior products. Therefore, we need to know some identification methods. The editor of the stainless steel bearing seat manufacturer will introduce the bearing identification method:  

1. The introduction of bearing manufacturers with seats should first look at the material used for bearing steel, which deserves attention in terms of hardness and precision.

2. Using high investment marking equipment, in order to establish a corporate brand image and prevent products from being counterfeited, bearing manufacturers have adopted laser marking machines, hoping to establish a corporate image and integrate with it, while using high investment to control products from being counterfeited. However, due to the advantages of using a computer to control laser marking machines, such as convenient editing of marking fonts and sizes, not only can effectively prevent counterfeiting, but also increases the difficulty for counterfeiters.

3. Bearing identification method: observation method. Visually observe the rolling bearing, and the inner and outer raceways should be free of peeling marks and severe wear, and have a circular groove shape; The surface of all rolling bodies shall be subject to stress, cracks, and peeling; The cage should not be loose, damaged, or worn through, and the gap with the rolling body should not be too large.

4. Hand feel method. The clearance between the inner and outer races of normal bearings and the rolling element is 0.005-0.00mm. For rolling bearings that have been used for one stage, there should be no obvious shaking noise when pinching the inner race with your fingers for axial shaking.

It is worth noting that you can find a common model to buy a set of stainless steel bearing seat manufacturers, confirm that it is, and then compare it with this sample if the supplier changes in the future. Find a more reliable supplier, cooperate for a long time, and make friends with your heart. Considering that he can still be a friend in long-term business, he won't deceive you.
