Airtac SDA Ultra Thin Cylinder SDA12X10BH
The AirTAC Airtac SDA Ultra Thin Cylinder SDA12X10BH is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm bore and 10mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.

About the Airtac SDA Ultra Thin Cylinder SDA12X10BH
The AirTAC SDA12X10BH is a double-acting single-rod compact cylinder engineered for tight machinery footprints. It generates 56.5 N of push force and 42.4 N of pull force at 0.5 MPa. This specific SKU includes a male M5x0.8 threaded piston rod for direct load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
Built with a hard-anodized 12 mm bore and a short riveted body, it saves substantial axial mounting depth compared to standard round-body units. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or add an external shock absorber for high-energy cycles. Because this configuration lacks the -S magnet option, it cannot host magnetic reed or electronic switches.

Where the Airtac SDA Ultra Thin Cylinder SDA12X10BH Is Used
PCB Pick-and-Place Ejection
Ideal for short 10 mm ejection strokes in electronics assembly, where the compact riveted body minimizes Z-axis height on dense pick-and-place heads.
Lab Dispenser Valve Actuation
The FKM seals handle chemical exposure in automated fluid dispensing, while the male M5x0.8 rod threads directly into small pneumatic valve stems.
Micro-Clamp Actuation
Provides 56.5 N of clamping push at 0.5 MPa for securing delicate micro-components during machining without overwhelming the part.
Is the Airtac SDA Ultra Thin Cylinder SDA12X10BH the Right Cylinder?
When sizing this 12 mm bore actuator, consider stepping up to the SDA16, which provides 100.5 N of push at 0.5 MPa if your payload demands more force. As the smallest available bore in the series, there is no smaller standard SDA option. The computed safe working load is approximately 34 N (about 60% of the 56.5 N figure), yielding a vertical lift capacity of roughly 2.9 kg with a 2:1 safety margin. Confirm your ordering essentials: 12 mm bore, 10 mm stroke, M5x0.8 port, male M5x0.8 rod thread, and FKM seals. Note that a plain cylinder drifts when air is lost or the valve is centered; the fixed bumper only decelerates near stroke end and never acts as a lock, so utilize an external rod lock or pilot-operated check valve for position holding.
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 SDA12X10BH FAQ
This double-acting 12 mm bore cylinder delivers 56.5 N push and 42.4 N pull at 0.5 MPa, 79.2 N push and 59.4 N pull at 0.7 MPa, with a theoretical maximum push of 12 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, proof pressure is 1.5 MPa, and the speed range is 30-500 mm/s.
No, this specific SKU lacks the -S magnet option, so it cannot host reed or electronic switches. Additionally, end-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, so external shock absorption is recommended for high-speed impacts.
