How to identify counterfeit stainless steel bearing seats?

Stainless steel bearing seat is an industrial part with the advantages of automatic centering, repeated lubrication, good dust proof sealing, and convenient installation and disassembly, achieving high strength. It can be widely used in various products that are prone to corrosion and strong corrosion. Let's take a look at how to identify the quality of stainless steel bearing blocks.

1. There is no official factory number or code.

2. The printing model and factory logo are unclear and non-standard, and the two ends are uneven and relatively rough.

3. The rolling cannot meet the requirements, and the surface roughness cannot meet the requirements, which is very rough.

4. The installation quality is poor, and the clearance is obviously out of tolerance due to manual shaking. The inner and outer ring chamfers of the same specification are not standardized. The inside of the outer ring and the outside of the inner ring are covered with black paint.

5. The hardness is not low, and can be obviously rubbed with a file. There are obvious marks when two bearings collide.
