Full title and description
St ISO 8131-1992 — Hydraulic fluid power — Single rod cylinders, 16 MPa (160 bar) compact series — Tolerances. This International Standard specifies tolerances for stroke (up to and including 1 250 mm) and for mounting dimensions in accordance with ISO 6020-2 to ensure interchangeability of compact single-rod hydraulic cylinders.
Abstract
Specifies dimensional tolerances for stroke lengths (up to and including 1 250 mm) and mounting dimensions for 16 MPa (160 bar) compact single‑rod hydraulic cylinder series, referencing ISO 6020-2 for mounting interfaces and interchangeability.

- ICS / categories: 23.100.20 (Cylinders).
- Edition / version: Edition 2 (1992).
- Number of pages: 4.
Scope
The standard applies to compact series single‑rod hydraulic cylinders rated at 16 MPa (160 bar). It defines the allowable tolerances for stroke lengths up to and including 1 250 mm and the associated mounting dimensions (as specified by ISO 6020-2) required to achieve mechanical interchangeability between manufacturers and assemblies. The scope focuses on dimensional interchangeability rather than performance, materials or testing.
Key topics and requirements
- Dimensional tolerances for stroke lengths up to 1 250 mm.
- Specified mounting dimensions and tolerances referencing ISO 6020-2 for interchangeability.
- Application to compact single‑rod cylinder series rated at 16 MPa (160 bar).
- Focus on geometric and mounting interchangeability (not on hydraulic performance testing or material specifications).
Typical use and users
Engineers and designers of hydraulic systems, cylinder manufacturers, OEM procurement and quality departments, maintenance and service teams, and standards committees use this standard as a dimensional reference to ensure parts interchangeability and compatibility between suppliers. It is primarily relevant to industries that rely on hydraulic cylinders — e.g., mobile equipment, industrial machinery and material‑handling systems.
Related standards
Relevant or related standards and documents include ISO 6020-2 (mounting and basic dimensions for certain cylinder types), the earlier ISO 8131:1986 (superseded by the 1992 edition), and various later or parallel standards covering hydraulic and pneumatic cylinder dimensions and design (for example ISO 15552 for pneumatic cylinders and industry-specific hydraulic cylinder design standards). Users should consult more recent standards and regional/adopted equivalents for up-to-date requirements.

FAQ
Q: What is this standard?
A: ISO 8131:1992 is an International Standard that defines dimensional tolerances and mounting dimensions for compact single‑rod hydraulic cylinders rated at 16 MPa (160 bar), to allow mechanical interchangeability.
Q: What does it cover?
A: It covers tolerances for stroke (up to and including 1 250 mm) and the mounting dimensions (as referenced to ISO 6020-2) necessary for interchangeability; it does not define performance testing, materials, or hydraulic circuit requirements.
Q: Who typically uses it?
A: Cylinder manufacturers, hydraulic system designers, OEM procurement and quality teams, maintenance and service engineers, and standards bodies use it as a dimensional reference to ensure parts fit and interchange correctly.
Q: Is it current or superseded?
A: ISO 8131:1992 has been withdrawn (the standard was withdrawn from active status; withdrawal noted by standards catalogues). Users should consult current ISO standards and regional/adopted documents covering hydraulic cylinder dimensions and safety for up‑to‑date requirements.
Q: Is it part of a series?
A: ISO 8131 is part of the family of standards addressing hydraulic fluid power and cylinder dimensions; an earlier edition was ISO 8131:1986 and related standards (for example ISO 6020-2) define compatible mounting dimensions and interfaces.
Q: What are the key keywords?
A: hydraulic, fluid power, single‑rod cylinder, compact series, tolerances, stroke, mounting dimensions, interchangeability, ISO 6020-2, 16 MPa (160 bar).
