In this video, let’s learn about the inner diameter code in the basic code. Generally, the inner diameter code is coded by different methods according to the different nominal inner diameters of the bearings.

In the last video, we learned that bearing code consists of the basic code, the prefix code, and the suffix code. The basic code consists of the bearing type code, the dimension series code, and the bore diameter code. Regarding type codes, please refer to the previous video for details.

As important mechanical component, rolling bearings have achieved international standardization in their main dimensions. Although ISO (the International Organization for Standardization)

We discussed the classification of rolling bearings based on their structure in last video. In addition to being classified by structure, rolling bearings can also be classified according to

There are various classifications of rolling bearings. In this video we sort out the classification of rolling bearings according to their structure.
