1. Feel the quality of rolling bearing through the surface

In the process of selling rolling bearings, many customers said that as long as the surface of rolling bearings is bright, the quality is good, which is wrong. The surface of rolling bearing should be dark bright, which is caused by whether the steel used for rolling bearing is up to the standard and the grinding process and cutting fluid used, among which the former two are the main ones.

2. Whether the chamfer is bright

The chamfering of rolling bearing does not decide the quality of rolling bearing, but it reflects the processing method of rolling bearing. Chamfering is black, which means that after heat treatment such as quenching, the hardness of rolling bearing is increased. Some people think that chamfering black is not good-looking, which is a mistake.

3. Installation methodThe integrated cage is better than the two bodies. Although the new technology uses the integrated cage, it only saves materials, and the performance of rotation is worse than the two bodies.

Generally speaking, the service life of rolling bearing is related to three factors. The first is the quality of rolling bearing itself. The second is the use environment. The third is the installation method.
