Overview
ISO 15524:2011 specifies a metric series of single-rod short‑stroke pneumatic cylinders designed for a maximum working pressure of 1 000 kPa (10 bar). The standard covers cylinders with bores from 20 mm to 100 mm (20, 25, 32, 40, 50, 63, 80, 100 mm), with and without magnetic function. These short‑stroke cylinders are not equipped with adjustable cushioning, so they are intended for applications where adjustable end‑of‑stroke cushioning is not required. Example ordering format: Short-stroke cylinder ISO 15524 – MB 1 – 40×30.
Key topics and requirements
- Bore sizes: Defines the included bore diameters (20–100 mm) in accordance with ISO 3320.
- Maximum working pressure: Rated for 1 000 kPa (10 bar).
- Nominal stroke: Stroke selections follow ISO 4393; maximum stroke length should not exceed 100 mm. Nominal stroke tolerances are specified.
- Dimensions & mounting: Basic dimensional requirements, mounting reference points and mounting types are defined to ensure interchangeability:
- MB 1 - Body, through bolt hole
- MX 8 - Head and cap, tapped
- MX 9 - Body, through two bolt holes and both ends tapped
- Identification & ordering: Provides standard ordering designation and the recommended identification statement for documentation.
- Scope exclusions: Cylinders in this series are not fitted with adjustable cushioning - important for system design constraints.
- Terminology & references: Uses vocabulary from ISO 5598 and references ISO 16030 (ports), ISO 6099 (mounting codes), ISO 3320 and ISO 4393.
Applications and users
Practical uses of ISO 15524 short‑stroke cylinders include:
- Machine builders and OEMs specifying compact actuators for packaging, material handling, assembly and pick‑and‑place operations.
- Pneumatic system designers and engineers creating layouts that require standard dimensional interchangeability at up to 10 bar.
- Component manufacturers producing cylinders to a common metric series for global compatibility.
- Procurement, quality and testing labs ensuring product documentation and test reports reference a recognized international standard.
Who benefits:
- Mechanical designers, automation integrators, maintenance teams and purchasing specialists seeking reliable, standardized cylinder dimensions and mounting options.
