Stainless steel deep groove ball bearings are composed of inner ring, outer ring and other components. They are durable and environmentally friendly, with fast running speed and small friction coefficient. The operation during use is also very convenient. With the continuous expansion, there are more and more dazzling products of stainless steel bearings on the market, which leads to great difficulties for users to choose. Today, I will tell you what misunderstandings are easy to make when choosing stainless steel bearings.

Misunderstanding 1. A bright surface is a good bearing
Judging the quality of stainless steel bearings by observing the surface is a method that many users prefer when choosing. Many customers say that as long as the bearing surface is bright, the quality is good. In fact, this is a misunderstanding, because the black brightness on the bearing surface is used by the bearing. Whether the steel meets the standard and its grinding process and the cutting fluid used, so it is one-sided to distinguish stainless steel deep groove ball bearings.

Misunderstanding 2. Bright chamfering is a good bearing
Some bearing chamfers on the market are bright, and some are really black. In fact, the chamfer is black, which means that the hardness of the bearing is increased by heat treatment such as quenching. Only the processing method of the bearing can be seen. Some users think that the chamfer is black when choosing. It is caused by incomplete processing, which is also a misunderstanding of selection.

Misunderstanding 3. One-piece cage is better than two-body cage
The bearings produced by the current new process all use an integrated cage, which only saves materials and has no effect on performance.
