How to identify the quality of stainless steel bearings?
There are many manufacturers selling stainless steel bearings on the market now, and the quality of each manufacturer is also uneven. Faced with so many choices, how can we choose to buy high-quality stainless steel bearings? Let me explain to you how to choose good stainless steel bearings.
1. Look at the material. The stainless steel of stainless steel bearings can be seen from their hardness and precision. In this regard, good stainless steel bearings are much higher than inferior stainless steel bearings.
2. We can observe the stainless steel bearings with the naked eye to see whether the inner and outer raceways are in the shape of an arc groove, whether there are signs of peeling, and whether there are cracks and peeling on the rolling surface, and whether the entire structure is loose.
3. Identify by feel. Generally, the gap between the inner and outer rings and rolling elements of normal stainless steel bearings will not be too large. When we shake the inner race in our hands, see if it shakes significantly. If so, it is an inferior stainless steel bearing.
4. Rotate the stainless steel bearing. If it is not flexible enough and feels blocked during the rotation, or if the stainless steel bearing shakes during the rotation, it is also a low-quality stainless steel bearing.
5. As for the price, we must always believe in the saying that you get what you pay for. We cannot make our losses greater because of greed. If the price of the stainless steel bearing is much lower than the normal market price, then you should be careful. This may be a shoddy product, because the cost of stainless steel bearings is relatively high. If the price is too low, even the basic cost cannot be achieved. How can it be a truly good and high-quality stainless steel bearing?
