About the Airtac SDA Ultra Thin Cylinder SDA12X10SB
The AirTAC SDA12X10SB is a double-acting, single-rod compact cylinder engineered for extremely tight axial spaces. A riveted unibody design integrates the barrel, rear cover, piston, and rod to drastically reduce mounting depth compared to conventional round-body units. Delivering 56.5 N of push force at 0.5 MPa, it handles light-duty positioning with a 10 mm stroke.
This configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. The -B option specifies a male M5x0.8 piston rod end, providing a robust external thread for load coupling. End-of-travel deceleration is managed by a fixed NBR bumper rather than an adjustable air cushion.

Where the Airtac SDA Ultra Thin Cylinder SDA12X10SB Is Used
PCB Ejector Pins
Provides a 10 mm tap to eject populated printed circuit boards from test fixtures, utilizing the male M5x0.8 rod thread for precise actuator attachment.
Microfluidic Valve Indexing
Shifts small lab diagnostic valves with a safe working load of 34 N, fitting easily into crowded analytical instruments via its ultra-short riveted body.
Electronic Component Sorting
Pushes miniature surface-mount components into packaging tubes, relying on the 56.5 N extend force and a built-in magnet for position confirmation.
Is the Airtac SDA Ultra Thin Cylinder SDA12X10SB the Right Cylinder?
When sizing this 12 mm bore actuator, evaluate your force margins carefully. At 0.5 MPa, the theoretical safe working load is approximately 34 N (about 60% of the 56.5 N output), translating to a vertical lift capacity of roughly 2.9 kg with a 2:1 safety factor. If your application requires slightly more thrust, the next size up, the SDA16, provides 100.5 N of push force at 0.5 MPa. Remember that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a lock. For suspended loads, integrate an external rod lock or pilot-operated check valve. To order, confirm the 12 mm bore, 10 mm stroke, M5x0.8 port, male M5x0.8 rod thread, and the required magnetic sensor.
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 SDA12X10SB FAQ
This double-acting 12 mm bore 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 force is 79.2 N and the pull force is 59.4 N. The theoretical maximum push force is 12 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa and a speed range of 30-500 mm/s.
No, the SDA12X10SB uses a fixed NBR bumper at each end to decelerate the piston near the stroke extremes; it is not an adjustable air cushion. Additionally, it cannot hold a load if air pressure is lost or the directional valve is centered, as the piston will drift. You must use an external shock absorber for high-energy stops and a pilot-operated check valve or rod lock for position holding.
