ISO 6020-3:2015

Hydraulic fluid power — Mounting dimensions for single rod cylinders, 16 MPa (160 bar) series — Part 3: Compact series with bores from 250 mm to 500 mm

ISO 6020-3:2015 establishes metric mounting dimensions for single rod compact series hydraulic cylinders with bores from 250 mm to 500 mm for use at 16 MPa (160 bar[1]), as required for interchangeability of commonly used hydraulic cylinders. NOTE 1 This part of ISO 6020 allows manufacturers of hydraulic equipment flexibility in the design of metric cylinders and does not restrict technical development, but does provide basic guidelines. NOTE 2 The compact series dimensions are most applicable to square-head cylinders. ISO 6020-3:2015 applies only to the dimensions of manufactured products. It does not apply to their functional characteristics. [1] 1 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.

Fluidna tehnika - Hidravlika - Vgradne mere za enosmerne valje vrste 16 MPa (160 barov) - 3. del: Kompaktna vrsta s premerom od 250 mm do 500 mm

Ta del standarda ISO 6020 določa vgradne mere za enosmerne hidravlične valje kompaktne vrste s premerom od 250 mm do 500 mm za uporabo pri tlaku 16 MPa (160 barov1)), kot je potrebno za medsebojno zamenljivost najpogosteje uporabljenih hidravličnih valjev.
OPOMBA 1: Ta del standarda ISO 6020 proizvajalcem hidravlične opreme omogoča uporabo prilagodljive zasnove metričnih valjev in ne omejuje tehničnega razvoja, temveč podaja osnovne napotke.
OPOMBA 2: Mere kompaktne vrste se uporabljajo predvsem za valje s kvadratno glavo. Ta del standarda ISO 6020 se uporablja samo za mere dokončanih proizvodov. Ne uporablja se za njihove funkcionalne lastnosti.

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

Introduction
In hydraulic fluid power systems, power is transmitted and controlled through a liquid 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, e.g. a piston and piston rod,
operating within a cylindrical bore.
