ISO 4394-1: Fluid Power Systems and Components - Cylinder Barrels - Part 1: Requirements for Steel Tubes with Specially Finished Bores First Edition
SDO: ISO: International Organization for Standardization
DOD Adopted ANSI Approved Approved
Scope and field of application
This part of ISO 4394 specifies the mechanical properties, dimensional tolerances, surface finishes and technical delivery conditions for round steel tubes, seamless or welded type, hot or cold worked condition, with plain ends and having specially finished bores with or without metal removal.
The tubes defined by this part of ISO 4394 are intended for use as barrels in a wide variety of fluid power cylinders.
NOTE - Steel should not be considered as the only material suitable for such applications.
This part of ISO 4394 defines the tube dimensions by inside diameter and thickness, or inside diameter and outside diameter.
Annex A specifies the tolerances on outside diameters for cold finished or machined tubes,
Annex B establishes a range of preferred thicknesses for metric bore sizes for fluid power cylinders. Tables of thicknesses are included for both cold finished and hot finished steel tubes.
Annex C provides a recommended method of ordering.
