There are many types of bearings, which are key components that mainly support flexible operation. However, there are many counterfeit products nowadays, and if we are not careful, we will be deceived and buy inferior products. Therefore, we need to know some identification methods. Below, the editor from the stainless steel bearing seat manufacturer will introduce the bearing identification method to you:
1. The introduction of bearing manufacturers with seats first focuses on the material used in bearing steel, which is worth paying attention to in terms of hardness and precision.
2. Using high investment marking equipment, in order to establish the corporate brand image and prevent product counterfeiting, bearing manufacturers have adopted laser marking machines. They hope to establish the corporate image, align with standards, and control product counterfeiting with high investment. However, due to the use of computer control, laser marking machines not only effectively prevent counterfeiting, but also increase the difficulty for counterfeiters.
3. Identification method for bearings: observation method. Observing the rolling bearings with the naked eye, there should be no peeling marks or severe wear on the inner and outer raceways, and they should be in a circular groove shape; All surface stresses, cracks, and peeling phenomena of rolling elements; The retainer should not be loose, damaged, or worn through, and the gap with the rolling element should not be too large.
4. Hand feel method. The clearance between the inner and outer race of a normal bearing and the rolling element is 0.005-0.00 millimeters. For rolling bearings that have been used for one stage, there should be no obvious shaking sound when pinching the inner race with fingers for axial shaking.
It is worth noting that stainless steel bearing seat manufacturers can purchase a set of commonly used models, confirm their availability, and then compare this sample if there are any changes in the supplier in the future. Find a reliable supplier, cooperate for a long time, and make friends with your heart. He considers that long-term business can still be friends, so he will not deceive you.
