7、SI 11-1998 National foreword This British Standard reproduces verbatim ISO 6981:1992 and implements it as the UK national standard. This British Standard is published under the direction of the Engineering Sector Board whose Subcommittee MCE/18/3 has the responsibility to: aid enquirers to understan
8、d the text; present to the responsible international committee any enquiries on interpretation, or proposals for change, and keep UK interests informed; monitor related international and European developments and promulgate them in the UK. NOTEInternational and European Standards, as well as oversea
9、s standards, are available from Customer Services, BSI, 389 Chiswick High Road, London W4 4AL. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does
10、not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, the ISO title page, page ii, pages 1 to 4, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had

12、py, (c) BSI BS ISO 6981:1992 ii 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 inter
13、ested 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
14、 Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Int
15、ernational Standard ISO 6981 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Sub-Committee SC 3, Cylinders. This second edition cancels and replaces the first edition (ISO 6981: 1982), Figure 1 and Table 1 of which have been technically revised. Annex A of this International Sta
16、ndard is for information only.

17、thin an enclosed circuit. One component of such systems is the fluid power cylinder. This is a device which 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. 1 Scope This International Standard
18、 specifies the mounting dimensions required for interchangeability of rod end plain eyes of hydraulic cylinders. The rod end plain eyes have been designed specifically for use with cylinders manufactured in accordance with ISO 6020-1 and ISO 6022, but this does not limit their application. The plain
19、 bearing end eyes are used on piston rods of hydraulic cylinders for mechanically transmitting the cylinder force. The design of these eyes is based on the maximum forces resulting from the specified internal diameters of the cylinders and pressures according to ISO 3320 and ISO 3322. 2 Normative re

At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International
