GB/T 2349-2026Fluid power - Basic series of piston stroke for cylinders (English PDF)

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".

This document supersedes GB/T 2349-1980 "Hydraulic and Pneumatic Systems and Components - Cylinder Piston Stroke Series" and is consistent with GB/T 2349-1980.

In comparison, aside from structural adjustments and editorial changes, the main technical changes are as follows.

a) The scope has been expanded (see Chapter 1);

b) Added terms and definitions (see Chapter 3);

c) A piston stroke annotation diagram has been added (see Figure 1);

d) The preferred piston stroke series dimensions were changed (see Table 1, Tables 1-3 of the 1980 edition).

This document is equivalent to ISO 4393:2015 "Fluid transmission systems and components - Cylinder piston stroke series".

---Change the standard name to "Piston Stroke Series of Hydraulic and Pneumatic Cylinders".

1 Scope
