About the Airtac SDA Ultra Thin Cylinder SDA100X25S
The AirTAC SDA100X25S is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial envelope. It generates a substantial 3927 N push force at 0.5 MPa, utilizing a robust 32 mm piston rod and a PT3/8 air port. The riveted unibody construction integrates the barrel, rear cover, and piston to drastically reduce overall length compared to conventional round-body actuators, saving valuable machine footprint.
Equipped with a built-in piston magnet (-S), this unit supports position detection via an AirTAC reed or electronic switch mounted into the peripheral body grooves. End-of-travel deceleration is handled by a fixed NBR bumper at each end rather than an adjustable air cushion, ensuring reliable impact absorption for this high-mass actuator. The hard-anodized bore and two-way piston seal ensure longevity in demanding industrial environments.

Where the Airtac SDA Ultra Thin Cylinder SDA100X25S Is Used
Injection Mold Ejection
Drives heavy ejector pins in automotive plastics molding, utilizing the 5497.8 N extend force at 0.7 MPa to reliably strip large bumper fascias from deep cavity tooling.
Heavy Press Staging
Indexes thick gauge steel blanks into a mechanical press line, where the short 25 mm stroke and 32 mm rod provide rigid, high-force positioning without axial overrun.
Pallet Lift Stations
Elevates loaded machining pallets weighing up to 200 kg, relying on the compact riveted body to fit within tight transfer arm clearances while maintaining a 2:1 lift margin.
Is the Airtac SDA Ultra Thin Cylinder SDA100X25S the Right Cylinder?
Selecting the SDA100X25S provides a theoretical maximum output of 801 kgf at 1.0 MPa, with a safe working load around 2356 N (approximately 60% of the 3927 N push at 0.5 MPa) and a vertical lift capacity of roughly 200.2 kg using a 2:1 safety margin. If your application requires less force, stepping down to the SDA80 yields 2513.3 N at 0.5 MPa; as the largest bore in the series, there is no larger standard SDA option. When ordering, confirm the 100 mm bore, 25 mm stroke, PT3/8 port, female M18x1.5 rod thread, and the required magnetic sensor option.
Keep in mind that a standard double-acting cylinder will not hold a load if air pressure drops or the valve is centered, as the piston will drift and the fixed bumper only decelerates near the stroke end rather than locking it. For vertical or suspended loads requiring fail-safe holding, an external rod lock or pilot-operated check valve must be integrated into your pneumatic circuit.
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 SDA100X25S FAQ
This 100 mm bore double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, increasing to 5497.8 N push and 4934.8 N pull at 0.7 MPa. The theoretical maximum push force is 801 kgf at the 1.0 MPa operating pressure limit.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion; for high-energy cycles, add an external shock absorber. The integrated magnet supports AirTAC reed or electronic switches in the body grooves for non-contact position detection.
