Ningbo bearing teaches you to distinguish three mistakes of NTN bearing quality!

The service life of Ningbo NTN bearing is related to three factors, one is the quality of NTN bearing itself. The second is the use environment. The third is the installation method. Improper use of these three reverse sides will result in damage of NTN bearing and equipment damage, and in light of this, the service life of NTN bearing and equipment working efficiency will be greatly reduced. The following are three misunderstandings in distinguishing NTN bearing quality.

1. Feel NTN bearing quality through surface

In the process of selling NTN bearing, I found that many customers said that as long as the surface of NTN bearing is bright, it is of good quality, which is wrong. The brightness of NTN bearing surface should be a kind of blackness, which is caused by whether the steel used in NTN bearing is up to standard, its grinding technology and cutting fluid, among which the former two are the main ones.  

2. Is the chamfering bright

The chamfering of NTN bearing does not determine the quality of NTN bearing, but it reflects the processing method of NTN bearing. The chamfering is black, which means that after heat treatment such as quenching, the hardness of NTN bearing is increased. However, some people think that the chamfering is not good-looking because it is not processed completely, which is a misunderstanding.  

3. The one-piece cage is better than the two-body cage. Although the new technology uses the one-piece cage, it only saves materials, and its performance on rotation is worse than that of the two-body cage.
