About the Airtac SDA Ultra Thin Cylinder SDA25X15
The AirTAC SDA25X15 is a double-acting single-rod compact cylinder engineered for tight axial spaces. The riveted body design integrates the barrel, rear cover, piston and rod to drastically reduce overall length compared to round-body units.
This specific configuration features a 10 mm piston rod and an M5x0.8 air port. End-stop deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorbers. Because this SKU lacks the S option, it has no piston magnet and cannot support magnetic sensing.

Where the Airtac SDA Ultra Thin Cylinder SDA25X15 Is Used
PCB Edge Guiding
Provides precise 15 mm lateral correction on an electronics assembly conveyor, utilizing the compact riveted body to fit within narrow machine profiles.
Carton Flap Folding
Actuates a short mechanical arm to tuck packaging flaps on a high-speed cartoner, where the fixed NBR bumper adequately absorbs the low-mass impact.
Lab Dispenser Positioning
Moves a fluid nozzle into exact position over vials, taking advantage of the 245.4 N extend force to ensure positive seating against a hard stop.
Is the Airtac SDA Ultra Thin Cylinder SDA25X15 the Right Cylinder?
When sizing this unit, you can step down to the SDA20 which provides 157.1 N of push at 0.5 MPa, or step up to the SDA32 which offers 402.1 N at the same pressure. To finalize your order, confirm the 25 mm bore, 15 mm stroke, M5x0.8 port, female rod-end thread (M5x0.8), and the absence of a magnet. If your process demands position holding upon air loss, note that the piston will drift; an external rod lock or pilot-operated check valve is required to secure the load.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short-body depth vs. a round-body cylinder
- ✓ Port/thread type (PT)
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
- ✓ Side load — avoid on a compact rod
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the short piston rod.
- check Very long strokes are unsuitable for the compact body.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDA Ultra Thin Cylinder SDA25X15 FAQ
At 0.5 MPa this cylinder provides 245.4 N push and 206.2 N pull. At 0.7 MPa it provides 343.6 N push and 288.6 N pull. The theoretical maximum push force is 50 kgf at 1.0 MPa, with an operating speed of 30-500 mm/s.
No, this specific SKU does not include the S option, meaning it lacks the internal piston magnet required for sensing. To use AirTAC reed or electronic switches, you must select the SDA25X15S variant which includes the built-in magnet.
