The standard code for bearings is 6 - 61805, for example, 6 for deep groove ball bearings, 18 for outer diameter and width size series, and 05 for internal size series. The code for the zero series can be omitted, so my bearing code is 4 bits and 5 bits. Specific bearing coding and naming rules

The series is not the same, after the general bearing type bearing diameter is multiplied by five
