Whether you will identify the quality of the robot bearing, we will discuss how to select good bearings.
1, lets start with the material used for bearing steel. The German FAG bearing is produced by its own professional steelworks, and its hardness and precision are all higher than those of the fake FAG bearings.
2, using high input marking equipment, in order to establish a corporate brand image, product to prevent counterfeiting, FAG bearing manufacturers use a laser marking machine, hope to establish a corporate image, and the international community at the same time, with high input to control the products being counterfeited, however, because the laser marking machine using computer control, marking font, size edit is convenient, not only can effectively prevent counterfeiting, but to increase the difficulty of counterfeiters.
3. Observation method. Observation of rolling bearing with the naked eye, both inside and outside the raceway there should be no signs of peeling and serious wear, and there is a circular groove; all the rolling surface should be no spots, cracks and peeling; cage should not be loose, no damage, no wear, and the rolling body but the big gap.
4. The sense of hand. The gap between the inner and outer ring of the normal bearing and the rolling body is 0.005 to 0.010 millimeters. For a rolling bearing that has been used in one stage, there should be no clear noise in the axial movement of the inner ring with the finger.
5. The method of rotation. One hand holds the inner ring of the bearing and the other hand turns the outer ring. The bearing should be able to rotate flexibly, and the radial sloshing should not be felt.
6, of course, look at the price. If the price is lower than normal, a lot of it may be a fake. Dont buy it. After all, it costs a lot, but after all, the cost is high, so the cost of imports is very high.
The above method is only a simple identification method, of course there are other ways such as can be judged from the color, precision, also can do from the brand choice, this is not one by one example, I hope these methods can help to you, our company is a professional production and sales of bearings, product variety, quality assurance, welcome you at any time to buy my company.
