Full title and description

Hydraulic fluid power — Mounting dimensions for single rod cylinders, 25 MPa (250 bar) series. This International Standard specifies metric mounting and interchangeability dimensions for single-rod hydraulic cylinders designed for a nominal pressure of 25 MPa (250 bar), to ensure compatibility between manufacturers and equipment designs.

Abstract

ISO 6022:2006 establishes the mounting (interchangeability) dimensions for single-rod hydraulic cylinders for a nominal pressure of 25 MPa (250 bar). The standard gives dimensional series and mounting types commonly used in industrial and mobile hydraulic applications to permit replacement and interchange of cylinders from different suppliers.

Scope

Specifies mounting and interchangeability dimensions for single-rod hydraulic cylinders intended for service at a nominal pressure of 25 MPa (250 bar). The scope covers the dimensional series, principal mounting styles and recommended basic dimensions needed so cylinders from different manufacturers can be fitted into the same machinery without custom modification. It does not cover detailed internal design, sealing systems, or materials beyond those necessary to define mounting interfaces.

Key topics and requirements

• Defined mounting interfaces and dimensional series for single-rod cylinders at 25 MPa (250 bar).
• Standardized hole patterns, flange, trunnion and eye dimensions to allow interchangeability.
• Designation of nominal bores and corresponding mounting dimension tables.
• Reference to related ISO committee technical definitions and withdrawal of earlier editions.
• Notes on limits of the standard (it addresses external mounting dimensions, not detailed internal construction or performance testing requirements).

Typical use and users

Used by hydraulic cylinder manufacturers, machine builders, OEMs, maintenance engineers, designers of mobile and industrial hydraulic systems, and procurement/specification teams who require interchangeable cylinder mounting interfaces. Also used by standards committees and conformity assessors when specifying or verifying mechanical interchangeability.

Related standards

Replaces and withdraws earlier documents such as ISO 6022:1981 and ISO 8137:1986; work items and draft revisions (ISO/CD 6022) have been recorded for future revision. Other ISO and national standards on hydraulic cylinder dimensions and connections (series on cylinders and mounting interfaces) are commonly referenced together with ISO 6022 when specifying complete cylinder families.

FAQ

Q: What is this standard?

A: ISO 6022:2006 is an International Standard that defines the mounting (interchangeability) dimensions for single-rod hydraulic cylinders rated for a nominal pressure of 25 MPa (250 bar).

Q: What does it cover?

A: It covers the external mounting interfaces and dimensional series (flanges, trunnions, rod eyes, hole patterns and principal dimensions) necessary for mechanical interchangeability of single-rod cylinders at 25 MPa. It does not specify internal seal designs, detailed performance tests, or materials beyond those required to define mounting interfaces.

Q: Who typically uses it?

A: Cylinder manufacturers, OEM designers, maintenance engineers, procurement/specifiers, and standards professionals who need standardized mounting dimensions to ensure interchangeability across suppliers and equipment.

Q: Is it current or superseded?

A: ISO 6022:2006 (Edition 2, 2006) is published and has been subject to ISO's periodic confirmation/review process; it was confirmed in recent reviews but is listed in ISO lifecycle records as a standard to be revised (work items and committee drafts have been recorded). Users should check with the national standards body or ISO for any published revision or replacement before final specification.

Q: Is it part of a series?

A: Yes — ISO 6022 is part of the ISO family of standards covering hydraulic cylinders and mounting dimensions; it replaces earlier editions (ISO 6022:1981, ISO 8137:1986) and is used alongside related ISO cylinder dimension standards and national equivalents. Drafts for updated parts or a revised ISO 6022 have been recorded as committee work (ISO/CD 6022).

Q: What are the key keywords?

A: hydraulic cylinder, single rod, mounting dimensions, interchangeability, 25 MPa, 250 bar, trunnion, flange, rod eye, ISO 6022.
