1 feeling through the surface of bearing quality

As long as the bearing surface brightness is good quality, this is wrong. The brightness of the bearing surfaces should be the kinds of glossy black, this raven bearing steel whether compliance and its grinding process and the use of cutting fluid arising, which the previous two main

2, the chamfer is bright

Bearing chamfer does not determine the quality of the bearings, but reflects the processing method of the bearing. Chamfer black, shows that, after hardening heat treatment, thus increasing the hardness of bearing, and some people think that the chamfer does not look good for black is not processed completely, this is a fault.

3, one frame better than the two-body, although the new technology to use one cage, but it only saves material, while the performance of the rotation and other than two-body.

Overall, the SKF bearing life and three factors has a relationship,

First bearing it is own quality; 

Second the use environment;

Third the installation method;
