1. Through the surface feel bearing quality: In the process of selling bearings, many customers said that as long as the bearing surface is bright, the quality is good, which is wrong. The brightness of the bearing surface should be bright, and the reason for this blackness is that the steel used in the bearing is up to standard and its grinding process and cutting fluid used, etc., the former two are the main ones.
2, chamfer is light: the chamfer of the bright bearing does not determine the quality of the bearing, but it reflects the processing method of the bearing. The chamfer is black, indicating that heat treatment such as quenching increases the hardness of the 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.
