What are the errors in judging the quality of deep groove ball bearings
The quality of the bearing is directly related to the credibility and effectiveness of the enterprise, and plays an important role in the working efficiency and service life of the bearing. Judging the quality of deep groove ball bearings is valued by users in various industries, and some misunderstandings in judgment are also common.
Misunderstanding 1: Judging the quality of the bearing by observing the surface of the deep groove ball
Judging the quality of the bearing can not only be analyzed from the aspect of whether the surface is bright. The bright surface of the bearing does not necessarily mean that the quality is good. Whether the steel used in the bearing is qualified, the grinding process and cutting fluid during the production of the bearing will cause the bearing surface to be shiny, which is one of the criteria for judging the quality of the bearing.
Misunderstanding 2: judging the quality of the bearing by whether the bearing chamfer is bright
The quality of the bearing is not determined by the chamfer. It can only reflect the processing method of the bearing during production. The chamfer of the bearing after heat treatment such as quenching is black, which can increase the hardness of the bearing. It is one of the misunderstandings to judge the quality of a bearing that the chamfer of the bearing is black and not good, and the quality of the bearing is not good.
Misunderstanding 3: Two-body cage is not as good as one-body cage
The latest bearing manufacturing processes use integrated cages, but this does not mean that integrated cages must be better than two bodies. Relatively speaking, the rotation performance of the two-body cage is better than the one-body cage, which only saves material.
