Full title and description

ISO 6432:2015 — Pneumatic fluid power — Single rod cylinders, 1 000 kPa (10 bar) series, bores from 8 mm to 25 mm — Basic and mounting dimensions. This International Standard establishes a metric series of basic and mounting dimensions to provide interchangeability of commonly used small pneumatic single‑rod cylinders (max working pressure 1 000 kPa / 10 bar).

Abstract

Specifies a metric series of mounting and basic dimensions for single‑rod pneumatic cylinders with bores from 8 mm to 25 mm and rated for up to 1 000 kPa (10 bar). The standard provides dimensional guidelines that allow manufacturers design freedom while supporting mechanical interchangeability of cylinder bodies and mountings.

Scope

Applies to single‑rod (single piston‑rod) pneumatic cylinders in the 10 bar (1 000 kPa) metric series with bore sizes from 8 mm up to 25 mm. It defines the basic and mounting dimensions required to achieve interchangeability of commonly used cylinder types while not restricting manufacturers' detailed design choices. The standard is intended for cylinders with fixed mountings described within its clauses.

Key topics and requirements

• Metric series of nominal bore and mounting dimensions for single‑rod cylinders (8–25 mm bores).
• Definition of basic dimensions and mounting interfaces to ensure mechanical interchangeability.
• Application limit: maximum working pressure 1 000 kPa (10 bar).
• Compatibility and cross‑reference to other fluid‑power dimensional standards (see related standards).
• Allows freedom of internal design while standardizing external mounting/face‑to‑face interfaces.

Typical use and users

Used by pneumatic cylinder manufacturers (product designers and mechanical engineers), machine and equipment designers, OEM purchasing and specification teams, maintenance engineers specifying replacement cylinders, and standards committees preparing product families or interoperability requirements. It is commonly used in industrial automation, robotics end‑effectors, handling equipment and OEM machinery that require standardized small bore cylinder mounts.

Related standards

Normative and related references commonly cited with ISO 6432: ISO 16030 (connections — ports and stud ends), ISO 3320 (cylinder bores and piston rod diameters — metric series), ISO 4393 (basic series of piston strokes), and earlier/related cylinder standards such as ISO 6431 / ISO 15552 family for larger or detachable mounting types. These documents together define dimensional series, identification codes and related interfaces for fluid power cylinders.

FAQ

Q: What is this standard?

A: ISO 6432:2015 is an International Standard that defines the basic and mounting dimensions for single‑rod pneumatic cylinders in a metric series for bores 8–25 mm at up to 1 000 kPa (10 bar), enabling mechanical interchangeability.

Q: What does it cover?

A: It covers external/basic and mounting dimensions (face‑to‑face, mounting holes/features, bore sizes in the 8–25 mm range) and specifies dimensional series for interchangeability; it does not prescribe internal design details or performance characteristics beyond the stated maximum working pressure.

Q: Who typically uses it?

A: Manufacturers and designers of pneumatic cylinders and equipment, OEM specifiers, procurement and maintenance teams who need standardized mounting interfaces, and standards committees referencing consistent dimensional series.

Q: Is it current or superseded?

A: ISO 6432:2015 is the current edition (Edition 2, 2015) that replaced the earlier 1985 version; ISO standards are normally reviewed on a five‑year cycle to determine if confirmation, revision or withdrawal is required. Check your national standards body or ISO for the latest review outcome if you need absolute current status.

Q: Is it part of a series?

A: Yes — it is part of a family of ISO fluid‑power cylinder dimensional standards (see ISO 3320 for bore/rod diameter series, ISO 16030 for ports, ISO 4393 for stroke series, and other cylinder standards such as ISO 6431 / ISO 15552 that cover different bore ranges or mounting types).

Q: What are the key keywords?

A: Pneumatic fluid power, single‑rod cylinder, mounting dimensions, metric series, bore 8–25 mm, 10 bar, interchangeability.
