ISO 15552 vs ISO 21287 Cylinders: Key Differences and Use Cases

ISO 15552 vs ISO 21287: Which Pneumatic Cylinder Fits Your Needs?

Both ISO 15552 and ISO 21287 are widely used pneumatic cylinder standards—but they serve different automation requirements. Understanding their distinctions helps optimize performance and footprint.

ISO 15552: The Industrial Workhorse

Also known as ISO 1/2, these tie-rod cylinders offer high force capacity (bore sizes 32–320mm) and robust construction. Ideal for heavy-duty applications like packaging, material handling, and automotive assembly lines. Fully compatible with Festo DSNU and SMC CP96S series.

ISO 21287: Compact and Space-Saving

Designed for tight spaces, ISO 21287 cylinders feature a sleek profile with integrated end caps. Bore sizes range from 20–100mm, making them perfect for robotics, small-scale automation, and medical equipment. Direct drop-in replacements for SMC CJ2 and Festo ADN series.
