Foreword
GB/T 273 "Rolling dimensions, general plan" is divided into three parts.
--- part 1. Tapered roller bearings;
--- part 2. thrust bearing;
--- part 3. radial bearings.
This section GB/T 273 Part 3.
This section drafted in accordance with the rules GB/T 1.1-2009 given.
This partial replacement GB/T 273.3-1999 "Rolling bearings general plan dimensions." And GB/T 273.3-1999
Compared, in addition to editorial changes, the main technical changes are as follows.
--- modified the standard name (see cover and first page, the cover of the 1999 edition and home);
--- modify the scope of the expression (see Chapter 1, 1999 edition of the Chapter 1);
--- an increase of some normative references (see Chapter 2);
--- added "Terms and definitions" (see Chapter 3);
--- modify some header dimensions table (see Table 1 and Table 8, 1999 edition of Table 1 and Table 8).
This method using an interpreter section identical with ISO 15.2011 "Rolling bearings general plan dimensions."
Consistency correspondence relationship with international documents in this section of our normative references the following documents.
--- GB/T 274-2000 Rolling maximum chamfer dimension (idtISO 582.1995);
Detent grooves on --- GB/T 305-1998 rolling bearing outer ring and snap ring dimensions and tolerances (eqvISO 464.1995);
--- GB/T 6930-2002 Rolling vocabulary (ISO 5593.1997, IDT);
--- GB/T 7811-2007 Rolling parameter symbols (ISO 15241.2001, IDT);

--- GB/T 20058-2006 Rolling row angular contact ball bearing outer ring non-thrust side chamfer dimensions (ISO 12044.
1995, IDT).
This section made the following editorial changes.
--- consistent with the existing series of standards, the standard name will be changed to "Rolling dimensions, general plan - Part 3. radial bearings."
This section was proposed by China Machinery Industry Federation.

introduction
The program (GB/T 273 of this section) to limit the number of dimensions of radial bearings, in order to fully ensure the economics of production, but also mention
Adequate size for the number of bearings to meet the current and future user needs.
These requirements are comprehensive and varied. Therefore, the program must cover a wide range of sizes and proportions, if desired, may even press
According to the present Standard Appendix A given rule extends.
Since the dimensions given in this section is not optimal for the following bearing, thus the normalized taper roller bearings, ball
Plane bearings, needle roller bearings and some types of instrument precision bearings without compliance with this section.
