Some standard content:
GB/T4199—2003
This standard adopts 15031132-1:2000 rolling bearing specification Part 1 Technical theory and definition 3 (English brand). This standard replaces GT4191984 dynamic bearing tolerance specification. This standard is based on ISO1132-1,2UH standard. Since the applicable parts in the standard are not "equivalent" to the corresponding international standards, this standard has made some changes when adopting 191321:2000. The relevant technical differences are marked with a vertical single line (:) in the blanks of the relevant paragraphs. In order to facilitate the use of this standard, the following changes have been made: - "this part" is changed to "this standard"; - the scale and foreword of the international standard are excluded; three of the language texts are deleted from the version including four language texts; - the standard name is collected; - for ease of use, the Hanno version given in alphabetical order is added: This standard recommends GR/T11S Compared with 1981, the main changes are as follows: Chapter 1 "Normative References" is added in the middle (Chapter 1 of 1984 edition; Chapter 1 of this edition); Chapter 2 "Normative References" is added (see Chapter 2); Chapter 3 "General Provisions" is added in the middle (Chapter 3 of 1984 edition; Chapter 3 of this edition); Chapter 4 "Some Terms and Their Definitions" is added (see 91.13); The names and definitions of terms, circles and circles are deleted (see 3.11 of 1984 edition); Chapters 5 and 6 are added with some terms and their equivalents and definitions (see 5.1.3, 5.1.12~6.1.16, 5.2.3, 5.2.12~3, 2, 1f, 5, 3, 6~5. 3. 9, 3. 16~5. 3. 21, 6. 3, 3): The definitions in the two chapters "Outline Dimensions" and "Reversal Accuracy" were reorganized. "Shape", "Surface Perpendicularity", "Micro-Track Parallelism" and "Henry Variation" were classified into the newly added "Geometric Tolerances" chapter (4.3, 5.3--5.6 of the 1954 edition, 6.1~5. 4
In Chapter 1, some terms and their symbols and definitions are added (see 7.1.3, 7.2.5, 7.2.6). The term "runout of the belt surface to the raceway" is revised (5.2 of the 1984 edition, 7.2 of this edition), and the term "runout of the inner surface S" and the variation of the outer surface line to the reference end surface S" and their definitions are revised (5.3, 5.5 of the 1984 edition; 3.3.1, 6. 3.2)
- The original appendix "New H terminology symbol comparison table" was deleted, and the informative appendix "Description of vertical dimension tolerance" was added (see Appendix A). Reference documents were added:
- The reference given by the unused section was added. Appendix A of this standard is an informative appendix.

1 Scope
Rolling bearing tolerance standard
GB/T4199-2003
This standard specifies the terms applicable to the outer dimension tolerance, form and position tolerance, rotation tolerance and internal tolerance of rolling bearings, and specifies the general terms used in these tolerances and the symbols of the following concepts defined. The principles and methods of measurement and inspection determined according to the definitions in this standard are shown in GH/307.2-1935. GB/69-2002 is an important supplement to this standard. 2 Normative references
The provisions of the following documents shall become the references of this standard through the use of this standard. For any dated referenced document, all subsequent amendments (excluding limited content) or subscribed versions are not applicable to this standard. However, parties to agreements based on this standard are encouraged to study whether the latest versions of these documents can be used. For any undated referenced document, the latest version applies to this standard.

root tear IS01: 1975, at 20°C, and when the bearing parts are completely unaffected by external forces (including load and self-weight of the parts), the overall dimensions of the bearing or bearing support should not exceed the tolerance range of its nominal dimensions. According to the definition of GB/T16892·1997, it is not applicable to non-standard parts in principle. For example, when checking the size and tolerance of stamped outer roller bearings, restrictions should be imposed on the common parts. Only the lower deviation of the inner diameter and the upper shrinkage difference of the outer diameter are applicable to the inner hole and outer surface of the entire width of the bearing. The definitions in 5.1, 5.2 and .1 are applicable to the surface between the flat sleeve and the sleeve. Unless otherwise specified, the terms "sleeve diameter", "inner diameter" and "outer diameter" in this standard are also referred to as "coil diameter", "shaft diameter" and "outer diameter" respectively. For face cone bearings, the terms "inner diameter" or "inner diameter" are now used to define "circular inner diameter", and "outer diameter" is defined by "outer diameter". In the terminology of dynamic bearings, the term "single" refers to a single inner diameter, a single outer diameter, etc. It has been used for convenience, but in its detection standard, it refers to "local, actual\, and its text is in G0/T1800.1-1997.
