Foreword
This standard replaces JB/T5302-1991 "Supplementary structural dimensions of outer spherical ball bearing seats".
Compared with JB/T5302-1991, the main changes in this standard are as follows: the bearing seat code has been changed (see Table 1 to Table 6); the structural type and overall dimensions of the boss square seat have been added (see Figure 6 , Table 6): The illustration of the adjustable diamond seat has been modified (see Figure 3): JB/T5302-2002
, "Marking" is a separate chapter (4.1, 4.2, 4.3, 1991 edition) 4.4, 4.5: Chapter 5 of this edition): Added informative appendix "Comparison of old and new code numbers of bearing seats" (see Appendix A). Appendix A of this standard is an informative appendix.
This standard is proposed by China Machinery Industry Federation. This standard is under the jurisdiction of the National Rolling Bearing Standardization Technical Committee (CSBTS/TC98). This standard was drafted by: Luoyang Bearing Research Institute. The main drafter of this standard: Ma Suqing.
The previous versions of the standard replaced by this standard are: JB/T53021991. | |tt | The structural type and overall dimensions of the cast seat for outer spherical ball bearings (hereinafter referred to as the bearing seat).
This standard applies to outer spherical ball bearing seats with six structural types: high-center vertical seat, vertical seat, adjustable diamond seat, suspended seat, suspended seat and boss square seat.
The bearing seat should be equipped with a lubrication device, and the position of the lubrication device should correspond to the position of the bearing oil hole in GB/T38821995. 2 Normative reference documents
The provisions in the following documents become provisions of this standard through reference in this standard. For dated reference documents, all subsequent amendments (excluding corrigenda) or revisions do not apply to this standard. However, parties to an agreement based on this standard are encouraged to study whether the latest versions of these documents can be used. . For undated referenced documents, the latest edition applies to this standard. GB/T3882-1995 rolling bearing outer spherical ball bearing and eccentric sleeve outer dimensions (neqISO9628:1992) GB/T7809-1995 rolling bearing outer spherical ball bearing seat outer dimensions (eqvISO3228:1993) 3 symbols
