Foreword
This standard replaces JB/6637 - 1993 (Technical Conditions for Standards for Rolling Bearings). Compared with JB/6637-1993, the main changes in this standard are as follows: Modified the writing format:
Changed the rolling bearing tolerance grade code (1993 edition and the 4th edition of this edition Chapter): Modified the surface roughness value of the rolling bearing cylindrical hole (cylinder) standard (5.3 of the 1993 edition, 5.4 of this edition): Modified the roundness and verticality tolerances of the rolling bearing ring cylindrical hole (cylinder) standard (Table 1 of the 1993 edition and this edition): Modified the chamfer dimensions of the standard instrument for rolling bearings (5.2 of the 1993 edition, 5.3 of this edition), and added Table 6: Removed the non-working standard instrument for movable bearings Surface technical requirements (5.3 of the 1993 edition): - Modified the technical requirements for the annual dimensional change of the Class I standard instrument for rolling bearings (1993 edition and 5.5 of this edition): Modified the acceptance rules for the standard instrument for rolling bearings (1993 Chapter 6 of the 1993 edition and this edition): The marking and anti-rust packaging of standard equipment for rolling bearings have been modified (Chapter 7 of the 1993 edition, Chapters 7 and 8 of this edition). This standard was proposed by the 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 drafters of this standard: Liu Guoqing and Zhang Junjie. The previous versions of the standards replaced by this standard are: - JB/T6637-1993.
