Now there are many manufacturers selling stainless steel bearings in the market, and the quality of each manufacturer is uneven. Facing so many choices, how can we choose to buy good stainless steel bearings? Now, let's talk about it.
1. Look at the material. The stainless steel of stainless steel bearings can be seen from their hardness and precision. In this respect, good stainless steel bearings are much higher than inferior stainless steel bearings.
2. We can observe it with the naked eye. Check whether the inner and outer raceways are in the form of arc grooves, whether there are peeling marks, whether there are cracks and peeling on the rolling surface, and whether the whole framework is loose.
3. Identify from the feel. Generally, the clearance between the inner and outer rings of a normal stainless steel bearing and the rolling element is not too large. When we shake the inner race with our hands, we check whether it shakes. If it does, it is inferior.
4. Rotate the stainless steel bearing. If it is not flexible enough and has a sense of obstruction during rotation, or if the stainless steel bearing shakes during rotation, it is also inferior stainless steel bearing.
5. Price. We should believe that the principle of "one cent for one price, one cent for one goods" should not make us lose too much because of greed for small things. If the price of stainless steel bearings is much lower than the normal market price, you should be careful. It may be that they are shoddy, because the cost of stainless steel bearings is relatively high. If the price is too low, even the basic cost cannot be reached. How can they be good stainless steel bearings.
