Foreword| |tt||This standard replaces JB/T5303-1991 "Supplementary structural dimensions of seated radial ball bearings". Compared with JB/T5303-1991, the main changes in this standard are as follows: the code name of seated radial ball bearings has been changed (see Table 1 ~ Table 6): Added three structural types and external dimensions of square seat bearings with bosses (see Figure 16, Figure 17, Figure 18, Table 6): Illustration of a pair of bearings with adjustable diamond seats Modified (see Figure 7, Figure 8, Figure 9); "Marking" is a separate chapter (6.1, 6.2, 6.3, 6.4, 6.5 of the 1991 edition; Chapter 6 of this edition): An informative appendix "With Comparison of old and new codes of seat bearings" (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 is initiated by: Luoyang Bearing Research Institute. This standard was first published in 1997. || tt | Structural type and overall dimensions of ball bearings (hereinafter referred to as seated bearings).
This standard applies to 2 series of spherical outer spherical ball bearings with high center vertical seat, narrow vertical seat, adjustable diamond seat, avoid hanging seat, avoid hanging seat and 3 series of square with boss Outer spherical ball bearing. 2 Normative reference documents
