Understanding rolling bearings
Thread Content
Help: 1) Width code: The fourth digit from the right in the bearing model is the width code. Example: 21315 is the width of the “1” series. 6205 is the width of the “0” series (it is actually 6(0)205; the width “0” has been omitted). “0” “1” “2” “3” “4” “5” “6”. . . . . . . . . . With the same inner diameter and the same outer diameter, the width dimension increases sequentially. In the above description, it is stated that \"with the same inner diameter and the same outer diameter, the width increases sequentially\"; how is this expressed for deep groove ball bearings? For example. 2) How is the preloading of the mated angular contact balls controlled? How is it detected?
