Bearing quality of judgment errors
Oct 25, 2016

1, surface quality

I found the bearings in the sales process said many customers as long as the bearing surface is of good quality and it was wrong. Bearing surfaces should be kind of glossy black, cause that Raven is the steel used in bearings are met and the grinding and cutting fluids, before two of them.

2, bright chamfer

Bearing the chamfer does not determine the quality of the bearings, but reflecting the processing method of the bearing. Chamfering is black, suggesting that after quenching and heat treatment to increase the hardness of bearing, and some people think badly of chamfer is black is not processed completely, this is a misunderstanding.

3, one more than two is good, although the new process using one cage, but it only saves the materials, such as Rotary and performance than the difference of the two.

All in all, the service life of the bearing has a relationship with 3 factors, one is the quality of the bearing itself. Second is to use the environment. Third, the installation method.
