A: 1, Feel the quality of the rolling bearing through the surface 

In the process of selling rolling bearings, many customers say that as long as the surface of the rolling bearing is bright, the quality is good, which is wrong. The brightness of the surface of the rolling bearing should be bright, and the reason for this blackness is that the steel used in the rolling bearing is up to standard and its grinding process and the cutting fluid used, etc., the former two are the main ones.

2. Is the chamfer bright?

The chamfer of the rolling bearing does not determine the quality of the rolling bearing, but it reflects the processing method of the rolling bearing. The chamfer is black, indicating that heat treatment such as quenching increases the hardness of the rolling bearing, and some people think that the chamfer is black and it is not processed completely. This is a misunderstanding.

3, The integrated cage is better than the two bodies, although the new process uses an integrated cage, but it only saves the material, and the performance of the rotation is worse than the two.

In general, the service life of rolling bearings is related to three factors, one is the quality of the rolling bearing itself. The second is to use the environment. The third is the installation method.
