scope:

This Standard specifies the snap ring groove dimensions and tolerance values, chamfer dimensions on the snap ring groove side of the outer ring, and the dimensions of locating snap ring (hereafter referred to as snap rings) and tolerance values for radial bearings in the dimension series 18 and 19 and the diameter series 0, 2, 3, and 4 (except dimension series 00, 82, and 83), as specified in JIS B 1512-1^[1].

NOTE 1 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 464:2015 Rolling bearings-Radial bearings with locating snap ring-Dimensions, geometrical product specifications (GPS) and tolerance values (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.

NOTE 2 An example of the design of housing components is given in Annex A, an example of drawing indications for specification for a snap ring groove in Annex B, and specifications of snap ring for rolling bearing unique to JIS in Annex JA, for reference.
