Preface
This document complies with the provisions of GB/T 1:1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents"
Drafting:
This document replaces GB/T 292-2007 "Outline Dimensions of Rolling Bearings Angular Contact Ball Bearings" and is consistent with GB/T 292-2007
In addition to structural adjustments and editorial changes, the main technical changes are as follows:
a) Added "Terms and Definitions", "Structural Type" and "Code" (see Chapter 3, Chapter 5 and Chapter 6);
b) The outer dimensions of the locking inner and outer ring type and locking outer ring type angular contact ball bearings of the 18 series when the contact angle is 25° are added (see
Table 1);
c) Expanded the size range of locking inner and outer ring type and locking outer ring type angular contact ball bearings (see Table 1 ~ Table 5,:2007 edition
Table 1 ~ Table 5);
d) Added the outer dimensions of 19 series locking inner ring angular contact ball bearings with contact angles of 15° and 25° (see Table 6);
e) Expanded the size range of 10 series and 02 series locking inner ring type angular contact ball bearings when the contact angle is 15° and 25° (see Table 7,
Table 8, Table 6 and Table 7 of the:2007 version);
f) Added the outer dimensions of the 03 series locking inner ring type angular contact ball bearings with contact angles of 15°, 25° and 40° (see Table 9):
