Standard based cylinders
Compact cylinder according to ISO 21287
Festo compact cylinders to ISO 21287, ADN series, are norm-compliant pneumatic cylinders with reduced installation length compared to ISO 15552 cylinders of the same bore size. The range covers bore sizes from 12 to 100 mm and offers a wide selection of stroke increments for each bore. The type designation follows the pattern ADN-[bore]-[stroke]-[cushioning]-[rod end]-[mounting], for example ADN-100-50-A-P-A (536380) for bore 100 mm, stroke 50 mm, with rubber-buffer end cushioning. Rod end versions I (internal thread) and A (external thread) allow flexible connection.

How to choose Compact cylinder according to ISO 21287
What matters when choosing: properties, comparison and typical applications.
ADN series: features and options
Selection by bore and stroke
| Bore | Piston area cm² | Force at 6 bar (single) | Typical stroke increments |
|---|---|---|---|
| ADN-12 | 1.13 | approx. 68 N | 10-40 mm |
| ADN-25 | 4.91 | approx. 295 N | 10-80 mm |
| ADN-50 | 19.6 | approx. 1,180 N | 10-100 mm |
| ADN-100 | 78.5 | approx. 4,710 N | 10-80 mm |
Typical applications
Typical applications: Compact linear drives in confined machine frames and multi-axis handling modules, clamping and locking tasks with defined stroke position, actuation units for diverters and slides in conveyor systems, replacement cylinders in existing systems with ISO 21287-compliant installation space without conversion, and positioning tasks with magnetic piston and Festo cylinder switches for end and intermediate position sensing.
