ICS 21.100.20 CCSJ11 National Standards of the People's Republic of China Replaces GB/T 4605-2003 rolling bearings Thrust needle rollers and cage assembly and thrust washers Published on 2025-10-31 Implemented on February 1, 2026 State Administration for Market Regulation The State Administration for Standardization issued a statement.

Foreword

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 supersedes GB/T 4605-2003 "Rolling Bearings Thrust Needle Rollers and Cage Assemblies and Thrust Washers", and is consistent with GB/T 4605- Compared to.2003, aside from structural adjustments and editorial changes, the main technical changes are as follows. a) The meanings of some symbols and the dimensional tolerance markings in the figures and tables have been changed (see Chapter 4, Figures 1 and 2, and Tables 1-3,.2003). (Chapter 4, Figures 1 and 2, and Tables 1 and 2 of the edition). b) The hardness requirements for the thrust washer and shaft raceway surfaces after heat treatment have been changed (see 8.1.1, 7.1.1 and A.2 of the.2003 edition); c) The surface roughness requirements for thrust washers and shaft raceways have been changed (see 8.3, 7.3 and A.3 of the.2003 edition); d) Added functional testing methods for inner and outer diameters (see 9.1.3 and 9.1.4). Please note that some content in this document may involve patents. The issuing organization of this document assumes no responsibility for identifying patents. This document was proposed by the China Machinery Industry Federation. This document is under the jurisdiction of the National Technical Committee on Standardization of Rolling Bearings (SAC/TC98).

1 Scope

This document specifies the designation, marking, dimensions, technical requirements, testing methods, and inspection procedures for thrust needle rollers, cage assemblies, and thrust washers. Inspection rules, markings, and rust-proof packaging. This document applies to the manufacture of general purpose thrust needle rollers and cage assemblies (hereinafter referred to as "assemblies") and thrust washers. Note. Thrust washers can be used as both shaft rings and seat rings.

3 Terms and Definitions

The terms and definitions defined in GB/T 6930 and GB/T 38762.1 apply to this document.

4 symbols

To indicate that the ISO /GPS system, namely GB/T 4249, is applied, the technical product documents (as shown in the figure) should include dimensions and geometric characteristics. Properties. The dimensional and geometric specifications related to these properties are described in Table 1 and Figures 1 and 2. The symbols are explained in accordance with GPS terminology. The tolerance value related to the characteristic is represented by t plus the characteristic symbol (subscript), such as tΔds. The default ISO dimensional specification operation set in this document is consistent with GB/T 38762.1, that is, two-point dimensions are valid. ...
