Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies) The work of preparing International Standards is normally carried out through ISO technical committees Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1 In particular the different approval criteria needed for the different types of ISO documents should be noted This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives)

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights ISO shall not be held responsible for identifying any or all such patent rights Details of any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents)

This third edition of ISO 3320 cancels and replaces the second edition (ISO 3320:1987) and the second edition of ISO 7181:1991, which have been combined and technically revised

ISO 3320:2013(E)

Introduction

In fluid power systems, power is transmitted and controlled through a liquid (for hydraulics) or a gas (for pneumatics) under pressure within an enclosed circuit

One component of such systems is the fluid power cylinder This is a device that converts power into linear mechanical force and motion It consists of a movable element, i.e a piston and piston rod, operating within a cylindrical bore

Fluid power systems and components — Cylinder bores and piston rod diameters and area ratios — Metric series

1 Scope

This International Standard establishes a metric series of cylinder bore and piston rod diameters for hydraulic and pneumatic cylinders, and specifies for each pair of diameters a corresponding standard ratio between the useful areas

This International Standard applies only to the dimensional criteria of products manufactured in conformity with this International Standard; it does not apply to their functional characteristics

2 Normative references

The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application For dated references, only the edition cited applies For undated references, the latest edition of the referenced document (including any amendments) applies

ISO 3, Preferred numbers — Series of preferred numbers

ISO 5598, Fluid power systems and components — Vocabulary

ISO 6099, Fluid power systems and components — Cylinders — Identification code for mounting dimensions

and mounting types

3 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 5598 apply

5 Dimensions

5.1 The cylinder bore diameter (AL) is shown in Figure 1 and values are specified in Table 2

5.2 The cylinder rod diameter (MM) is shown in Figure 1 and values are specified in Table 3

6 Area ratios

6.1 For each pair of diameters of bore and piston rod, there is a corresponding ratio between the useful

areas

6.2 Ratios approximately equal to one of the following preferred numbers are shown in Table 4:

1,06 — 1,12 — 1,25 — 1,33 — 1,4 — 1,6 — 2 — 2,5 — 5

6.3 Moreover, for each pair of diameters of bore (AL) and piston rod (MM), Table 4 gives calculated

values of A1 and A2 and their corresponding effective value ϕ.

7 Identification statement (reference to this International Standard)

It is recommended to manufacturers who have chosen to conform to this International Standard that the following statement be used in test reports, catalogues, and sales literature:

“Cylinder bores, piston rod diameters and ratios selected in accordance with ISO 3320, Fluid power

systems and components — Cylinder bores and piston rod diameters and area ratios — Metric series.”
