Foreword
This Standard was drafted as per the rules specified in GB/T 1.1-2009.
This Standard replaced GB/T 288-1994 Rolling Bearings - Self-Aligning Roller
Bearings - Boundary Dimensions. Compared with GB/T 288-1994, the major technical
changes of this Standard besides the editorial modifications are as follows:
--- Delete some schematic diagrams of the bearing structure (see Figure 1 ~ Figure
3, Figure 7, Figure 9 ~ Figure 16 of the 1994 Edition);
--- Increase the boundary dimensions of the 38, 39, 48 and 49 series bearings (see
Table 1 ~ Table 4 of this Edition);
--- Delete the relevant cage code (see Table 1 ~ Table 14 of the 1994 Edition);
--- Increase the boundary dimensions of some series of bearings (see Table 5 ~
Table 10, Table 12, Table 14 and Table 16 of this Edition);
--- Delete the relevant dimensions of the adapter sleeve (see Table 13 ~ Table 18
of the 1994 Edition);
--- Increase the structure diagram and boundary dimensions of the 22 and 23 series
sealed bearings (see Appendix A of this Edition);
--- Delete the comparison between the old and new code (see Appendix A of the
1994 Edition).
This Standard was proposed by China Machinery Industry Federation.
This Standard shall be under the jurisdiction of National Technical Committee for
Standardization of Rolling Bearings (SAC/TC 98).
