Criteria for distinguishing rolling bearings
Thread Content
May I ask how one can tell, just by looking at them, what type of bearing a rolling bearing is? Also, how can one determine whether a bearing is subjected to radial force, axial force, or both? Many bearings have very similar shapes!
I think it’s generally possible to tell what type of bearing it is; if you collect a few used or scrapped bearings, it will become clear
From personal experience, it’s necessary to find the model number on the bearing, which is usually located on the outer ring. The rolling bearing models corresponding to 1-7 can all be determined. If there is axial movement, then an axial force will definitely be applied. As for radial forces, each bearing generally has to withstand them; therefore, combined radial and axial loads are the most common scenario: lol
. It can be determined based on the numbers in the first column on the bearing
There’s no need to look at the actual item; just by understanding the classification of bearings, one can figure it out

For new bearings, just check the model number; for old bearings, it is possible to determine their type by looking at the inner and outer rings, the balls, and the retainers. A good website for checking bearing models is http://www.sozc.cn/
The first character of a bearing generally indicates its type; it’s quite simple – you can find out by searching on Baidu
