foreword
This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents"
drafted:
This document replaces GB/T 309-2000 "Rolling Bearing Needle Roller", compared with GB/T 309-2000, except for structural adjustment and editorial
In addition to the changes, the main technical changes are as follows:
a) Some terms and symbols are deleted (see Chapter 3 of the:2000 edition);
b) Changed the meaning of some symbols and the dimension tolerance annotations in figures and tables (see Chapter 4, Figure 1, Figure 2 and Table 3, Table 4;:2000
Edition Chapter 3, Figure 1, Figure 2 and Table 2);
c) Added the dimensions of some needle rollers (see Table 2);
d) Changed the detection method of chamfer size (see 7:4, 7:3 of the:2000 edition):
This document refers to ISO 3096:2018 "Outline dimensions, product geometric specifications (GPS) and tolerance values of needle rollers for rolling bearings"
