Festo ADN Series – Compact Cylinder to ISO 21287
The Festo ADN-16-15-A-P-A is a space-saving, double-acting compact cylinder designed and manufactured to ISO 21287 — the international standard for compact pneumatic cylinders. With a 16 mm bore and a 15 mm stroke, this unit fits into automation layouts where a full-size cylinder simply will not go, yet it delivers reliable, repeatable linear force at up to 10 bar working pressure. The ADN series is widely used across South Indian industries precisely because it combines ISO-standard interchangeability, cleanroom suitability, and a robust aluminium-and-steel construction in a package that is easy to mount, connect, and maintain.
Key Features
- ISO 21287 Compliant — Drop-in replacement compatibility across brands; reduces downtime when sourcing spares on urgent breakdowns.
- Double-Acting Operation — Air pressure drives both advance and return strokes, giving controlled, predictable motion in both directions without spring dependency.
- 121 N Advance / 90 N Return Force at 6 bar — Adequate gripping, clamping, or pushing force for small-part handling tasks without oversizing the cylinder.
- Elastic Cushioning at Both Ends — Integrated rubber cushioning rings absorb end-of-stroke impact (0.15 J), reducing mechanical shock on the cylinder and connected tooling without requiring external shock absorbers.
- M5 Pneumatic Connection — Standard M5 threaded ports keep the installation footprint small and are compatible with the full range of Festo QS push-in and NPQH fittings.
- Proximity Switch-Ready — Designed for position detection via proximity switch (sensor slot/groove present); enables position feedback without adding external brackets in most configurations.
- Cleanroom Class 5 (ISO 14644-1) — Validated for use in clean environments; suitable for pharmaceutical packaging, medical device assembly, and precision electronics lines.
- LABS/PWIS Conformity (VDMA 24364-B1/B2-L) — Paint-wetting impairment substance free; safe for use on automotive painting lines and wherever coating adhesion is critical.
- Anodised Aluminium Barrel and Cover — Smooth anodised bore provides a consistent sealing surface and good corrosion resistance (CRC 2 — moderate corrosion stress).
- Multiple Mounting Options — Through-hole mounting, female thread mounting, and accessory-based mounting give flexibility in machine integration.

Common Applications
- Textile Machinery, Coimbatore — Compact clamping and thread-tensioning mechanisms on ring frames, winding machines, and warping creels where space is severely constrained.
- Pharmaceutical and Medical Packaging — ISO Class 5 cleanroom rating makes this cylinder directly applicable on blister packing, capsule filling, and vial-handling lines without special dispensation.
- CNC Machine Tools and Machining Centres — Small workpiece clamping fixtures, tool-change actuators, and chuck jaw positioning where a short, precise stroke is needed.
- Plastic Injection Moulding — Ejector assist, sprue gate actuation, and part pick-and-place on mould platens; low moving mass (24 g) reduces cycle time impact.
- Food and Beverage Processing — LABS/PWIS conformity and cleanroom suitability suit filling line diverters, conveyor stops, and lid-placement heads in hygienic environments.
- Electronics and PCB Assembly — Precision component insertion, board clamping, and connector pressing where fine force control and repeatability matter.
