About the Airtac SDA Ultra Thin Cylinder SDA12X10SN
The AirTAC SDA12X10SN is a double-acting single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly integrates the barrel, rear cover, piston, and rod to drastically reduce axial mounting depth compared to round-body units. Delivering 56.5 N of push force at 0.5 MPa, it handles light-duty positioning with a 10 mm travel range.
This 12 mm bore variant features a hard-anodized inner wall and a two-way piston seal for reliable friction-free motion. The included S option provides a built-in piston magnet, allowing you to mount AirTAC reed or electronic switches directly into the body grooves for end-of-stroke sensing. End stops rely on a fixed NBR bumper rather than an adjustable air cushion, effectively decelerating the stroke ends.

Where the Airtac SDA Ultra Thin Cylinder SDA12X10SN Is Used
PCB Pick-and-Place Ejection
Provides a short 10 mm ejection stroke for delicate printed circuit board handling, where the 56.5 N push force safely clears components without stressing the panel.
Microfluidic Valve Actuation
Drives small pneumatic flow valves in laboratory diagnostic equipment, utilizing the built-in magnet to trigger electronic switches for precise dispensing cycles.
Electronic Component Sorting
Indexes tiny surface-mount resistors into packaging tubes, saving valuable axial depth within high-density semiconductor assembly machinery.
Is the Airtac SDA Ultra Thin Cylinder SDA12X10SN the Right Cylinder?
When sizing this 12 mm bore actuator, evaluate your force margins carefully. The SDA12X10SN yields a safe working load of roughly 34 N, which is about 60 percent of its 56.5 N push capacity at 0.5 MPa, and can vertically lift approximately 2.9 kg with a 2:1 safety factor. If your application demands slightly more thrust, stepping up to the SDA16 bore increases the push force to 100.5 N at 0.5 MPa. As the smallest available bore in this series, there is no smaller standard option to step down to.
To finalize your order, verify the 12 mm bore, 10 mm stroke, and M5x0.8 air port. This configuration includes the S magnet code for position sensing. The standard female M3x0.5 rod-end thread couples to your load, but remember that a plain compact cylinder drifts if air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. For suspended loads, integrate an external rod lock or 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 SDA12X10SN FAQ
This 12 mm bore double-acting cylinder generates a push force of 56.5 N and a pull force of 42.4 N at 0.5 MPa. At 0.7 MPa, the push increases to 79.2 N and the pull to 59.4 N. The theoretical maximum push is 12 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.
The cylinder uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits. It is not an adjustable air cushion, so for high-speed applications you may need an external shock absorber. Additionally, the bumper is not a locking brake; the piston will drift if air pressure is lost, requiring a pilot-operated check valve for load holding.
