Rolling numerous types and sizes, in order to facilitate the design and selection, standard specifies the code represented by the rolling dental bearing type, size, structure, characteristics and tolerance level and so on. (Alternative GB272-88), Rolling Code constitutes as shown in the table. Rolling Code code representation purposes: to characterize the structure of the rolling bearing, size, type, precision, code constitutes: Front code - said deep groove ball bearing bearing subassembly basic code - said after bearing types and sizes, such as the main feature set code - indicates the accuracy of the material bearing the characteristics of diameter code: ID Code × 5 = internal diameter special case: d = 10 12 15 17 code is: 00010203 size series Code: used to express the same outside diameter and width of the inner diameter but different bearings, see right. OD Series Code: special light (0,1), light (2), middle (3), weight (4) Width Series Code: normal width to "0", usually not marked. But for tapered roller bearings (3 classes) and spherical roller bearings (class 2) can not omit the "0"
