1. Feeling the quality of the bearing through the appearance. In the process of selling the bearing, I found that many customers said that only the external light of the bearing is good quality; this is wrong. The brightness of the bearing should be black and bright; the reason for this black light is Whether the steel used in the bearing can be qualified and its grinding process and the cutting fluid used, etc.;
2, chamfering whether 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; clarify the heat treatment by quenching, etc.; thus adding the hardness of the bearing; and some people think that the chamfer is Black is not good looking is not processed completely; this is a misunderstanding.
3, one cage is better than the two; although the new process uses an integrated cage; but it only saves data; and the performance of the reverse is worse than the two.
In general; the service life of the bearing is related to three elements; one is the quality of the bearing itself. The second is the use of the environment. The third is the installation method.
