About the Airtac SDA Ultra Thin Cylinder SDA12X30SB
The AirTAC SDA12X30SB is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly minimizes axial mounting depth, fitting where round-body units cannot. Delivering 56.5 N of push force at 0.5 MPa, it handles light-duty positioning with a 6 mm piston rod and an M5x0.8 air port.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. It also features a male-thread M5x0.8 piston rod (-B), providing a robust mechanical coupling for your load. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion.

Where the Airtac SDA Ultra Thin Cylinder SDA12X30SB Is Used
PCB Component Pick-and-Place
Ideal for small electronic assembly robots, using its 56.5 N thrust to push lightweight connectors onto printed circuit boards within a shallow frame.
Lab Sample Ejection
Provides a compact 30 mm stroke to eject vials from analytical centrifuges, where the male M5x0.8 rod threads directly into a custom ejector arm.
Micro-Clamp Actuation
Drives tiny pneumatic clamps in dental device machining, saving valuable Z-axis space while the magnetic sensor tracks the 30 mm travel.
Is the Airtac SDA Ultra Thin Cylinder SDA12X30SB the Right Cylinder?
For sizing context, stepping up to the SDA16 increases thrust to 100.5 N at 0.5 MPa, while this 12 mm bore provides a safe working load around 34 N (roughly 60% of its 56.5 N capacity) and a vertical lift capability of about 2.9 kg with a 2:1 safety margin. Since the 12 mm bore is the smallest available, choose the 16 mm option if your application demands greater force.
When ordering, confirm the 12 mm bore, 30 mm stroke, M5x0.8 port, male M5x0.8 rod thread, and the integrated magnet. Note that this unit does not hold its position if air pressure drops; the piston will drift, and the fixed bumper only decelerates near stroke end. Use an external rod lock or pilot-operated check valve for load 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 SDA12X30SB FAQ
This 12 mm bore double-acting cylinder generates 56.5 N push and 42.4 N pull at 0.5 MPa. At 0.7 MPa, it yields 79.2 N push and 59.4 N pull. The theoretical maximum push is 12 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, the SDA12X30SB uses a fixed NBR bumper at each end to decelerate the piston, not an adjustable air cushion. For high-speed or high-energy cycles, you should slow the approach speed or add an external shock absorber to prevent damage.
