Foreword

GB/T 5800 "Rolling instrument precision bearings" is divided into two parts. --- Part 1. Metric series bearing dimensions, tolerances and characteristics; --- Part 2. Inch series bearings dimensions, tolerances and characteristics. This is Part 1 GB/T 5800's. Rules in this section in accordance with GB/T 1.1-2009 given draft. This Part replaces GB/T 5800-2003 content "Rolling instrument precision bearings" Metric series section, and GB/T 5800- Compared to 2003, in addition to editorial changes outside the main technical changes are as follows. --- Deleted the contents of inch series bearings (see 2003 edition of the Table 3, Table 4, Table 9 and Table 10, Tables 5 to 8 and 11 Part of the contents); --- Modify some of the terms and definitions (see 31, 2003, version 3.1.); --- Modify some symbols (see Chapter 4, 2003 edition of the Table 1); --- Increasing the angular contact ball bearing structure schematic diagram [see Figure 1b)]; --- Modify the inner end face of the vertical bore (Sd) formula (see Table 2 and Table 4, 2003 edition of the tables 5 and 7). This section uses the translation method identical with ISO 1224-1.2007 "Rolling Instrument precision bearings - Part 1. Metric series Bearing dimensions, tolerances and characteristics. " Consistency correspondence between this part of international documents and normative references of our files are as follows. --- GB/T 273.3-1999 Rolling bearings dimensions, general plan (eqvISO 15.1998) --- GB/T 274-2000 Rolling chamfer dimensions Max (idtISO 582.1995) --- GB/T 4199-2003 Rolling defined tolerances (ISO 1132-1.2000, MOD) --- GB/T 7811-2007 Rolling Parameter Symbol (ISO 15241.2001, IDT) This part is proposed by China Machinery Industry Federation.
