About the Airtac SDA Ultra Thin Cylinder SDA12X10SH
The AirTAC SDA12X10SH is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly minimizes axial mounting depth where standard round bodies cannot fit, yielding a push force of 56.5 N at 0.5 MPa. The unit includes a built-in piston magnet for position sensing and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
This 12mm bore model features a 6mm piston rod and M5x0.8 air ports. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Operating speeds span 30-500 mm/s, making it suitable for rapid, short-stroke actuation tasks.

Where the Airtac SDA Ultra Thin Cylinder SDA12X10SH Is Used
PCB Edge-Guiding
Positions thin electronic boards on an SMT line using its 10mm stroke and 56.5 N force, fitting easily into dense conveyor clearances.
Lab Dispenser Pinch Valve
Actuates a small pinch valve for chemical dosing, where the FKM seals resist oil exposure and the compact body saves deck space.
Film Tensioner Arm
Tensions thin packaging film webs via a magnetic reed or electronic switch to confirm the 10mm travel endpoint.
Is the Airtac SDA Ultra Thin Cylinder SDA12X10SH the Right Cylinder?
When sizing this 12mm bore actuator, stepping up to the SDA16 provides 100.5 N of push force at 0.5 MPa for heavier demands, while the SDA12 offers a safe working load of roughly 34 N (about 60% of its 56.5 N capacity) or a 2.9 kg vertical lift with a 2:1 safety margin. Be aware that a standard cylinder drifts if air pressure drops or the valve centers; the fixed bumper only slows the piston near stroke end and cannot lock a load. For suspended loads, integrate an external rod lock or pilot-operated check valve. To order, confirm the 10mm stroke, M5x0.8 port, female M3x0.5 rod thread, S magnet option, and H FKM seal.
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 SDA12X10SH FAQ
This 12mm bore double-acting cylinder provides a push of 56.5 N and pull of 42.4 N at 0.5 MPa, and a push of 79.2 N at 0.7 MPa. The theoretical maximum push is 12 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa at speeds of 30-500 mm/s.
No, the piston will drift if air is removed or the valve is centered. The fixed NBR bumper only decelerates the rod near the end of its stroke and does not act as a locking brake. To maintain vertical position without live pressure, you must add an external rod lock or a pilot-operated check valve.
