Airtac SDA Ultra Thin Cylinder SDA25X30
The AirTAC SDA Ultra Thin Cylinder SDA25X30 is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 30mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.

About the Airtac SDA Ultra Thin Cylinder SDA25X30
The AirTAC SDA25X30 is a double-acting single-rod compact cylinder engineered to deliver 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. Its riveted assembly significantly reduces axial mounting depth, making it ideal for machinery where a standard round-body unit would protrude too far. The hard-anodized bore and two-way piston seal ensure reliable service across millions of cycles.
This specific SKU features a 10 mm piston rod and an M5x0.8 air port, operating at speeds from 30-500 mm/s. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or add external shock absorbers for high-energy loads. Because this base model lacks the -S magnet suffix, it cannot host position-sensing switches.

Where the Airtac SDA Ultra Thin Cylinder SDA25X30 Is Used
PCB Depaneling Router
Provides the 245.4 N push required to clamp printed circuit boards during automated routing and depaneling processes without excessive axial footprint.
Carton Flap Folding
Actuates folding mechanisms on packaging lines to close corrugated carton flaps, utilizing the 30 mm stroke for rapid, short-distance movements.
Sorter Diverter Gate
Pivots diverting arms on conveyor sorting systems where the 12.5 kg vertical lift capacity easily manages lightweight plastic or aluminum gate panels.
Is the Airtac SDA Ultra Thin Cylinder SDA25X30 the Right Cylinder?
When sizing this unit, evaluate your force requirements carefully. Stepping down to the SDA20 reduces the 0.5 MPa push capacity to 157.1 N, while moving up to the SDA32 increases it to 402.1 N. Ensure your ordering essentials match your assembly: 25 mm bore, 30 mm stroke, M5x0.8 port, female rod thread (M5x0.8), and no sensor magnet.
Keep in mind that a plain compact cylinder does not hold its load if air pressure drops or the valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the stroke end without acting as a lock or brake. If your application demands position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
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 SDA25X30 FAQ
At 0.5 MPa, the push force is 245.4 N and the pull force is 206.2 N. At 0.7 MPa, the push force is 343.6 N. The theoretical maximum push force is 50 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and the operating speed ranges from 30-500 mm/s.
No. This model uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. Additionally, because it lacks the -S option code, it does not have a built-in piston magnet and cannot be used with reed or electronic switches.
