About the Airtac SDA Ultra Thin Cylinder SDA25X5
The AirTAC SDA25X5 is a double-acting single-rod compact cylinder engineered for extremely short linear movements. It delivers a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa, making it suitable for high-cycle clamping or ejecting tasks. The riveted body assembly drastically reduces axial mounting depth compared to round-body alternatives, saving valuable machine footprint.
This specific configuration features a 5 mm stroke, a 10 mm piston rod, and an M5x0.8 air port. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber. Note that this SKU lacks a piston magnet, so it cannot host magnetic switches without upgrading to the -S option.

Where the Airtac SDA Ultra Thin Cylinder SDA25X5 Is Used
PCB Edge Clamping
Provides 245.4 N of extend force at 0.5 MPa to grip circuit boards securely in an SMT pick-and-place fixture without consuming valuable Z-axis height.
Film Cutting Anvil
Drives a short 5 mm stroke to press a sealing blade against a packaging roller, utilizing the compact riveted body to fit within narrow vertical sealing jaws.
Small Part Ejection
Ejects stamped metal micro-components from a die set, offering a safe working load of 147 N to push parts clear of the tooling during high-speed cycling.
Is the Airtac SDA Ultra Thin Cylinder SDA25X5 the Right Cylinder?
When sizing this actuator, evaluate your force margins carefully. If you need less thrust, stepping down to the SDA20 provides 157.1 N of push at 0.5 MPa, while moving up to the SDA32 yields 402.1 N for heavier loads. For this 25 mm bore, a safe working load is approximately 147 N (about 60% of the 245.4 N capacity at 0.5 MPa), translating to a vertical lift capability of roughly 12.5 kg with a 2:1 safety margin.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed NBR bumper only decelerates the stroke end without locking the piston. If your application demands strict position holding, incorporate an external rod lock or a pilot-operated check valve. To order, confirm the 25 mm bore, 5 mm stroke, M5x0.8 port, female rod-end thread, and the absence of a sensor magnet.
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 SDA25X5 FAQ
The SDA25X5 generates a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa. At 0.7 MPa, the push force is 343.6 N and pull is 288.6 N. The theoretical maximum push force is 50 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot support reed or electronic switches. You must select the -S option (SDA25X5S) to enable magnetic sensing. Additionally, end-stop deceleration relies on a fixed NBR bumper, which is not an adjustable air cushion.
