Airtac SDA Ultra Thin Cylinder SDA12X30B
The AirTAC Airtac SDA Ultra Thin Cylinder SDA12X30B is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm bore and 30mm 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 SDA12X30B
The AirTAC SDA12X30B is a double-acting single-rod compact cylinder engineered for tight spaces, delivering a 56.5 N push at 0.5 MPa. Its short riveted body merges the barrel, rear cover, and piston to drastically reduce axial mounting depth compared to round-body alternatives. This specific SKU features a male M5x0.8 threaded piston rod for direct load coupling.
This 12mm bore unit operates at 30-500 mm/s and relies on a fixed NBR bumper at each end to decelerate the stroke. Because this configuration lacks the -S magnet option, it cannot accept magnetic reed or electronic switches. The hard-anodized bore ensures durability within its 0.15-1.0 MPa operating pressure range.

Where the Airtac SDA Ultra Thin Cylinder SDA12X30B Is Used
PCB Component Pick-and-Place
Ideal for small electronic assembly robots where the 56.5 N push force securely transfers delicate components without requiring excessive axial mounting depth.
Lab Analyzer Sample Routing
Provides reliable 30mm linear actuation for micro-fluidic valve switching in diagnostic equipment, fitting neatly into compact instrument chassis.
Thin Film Sealing Jaws
Drives lightweight sealing mechanisms in vertical form-fill-seal machines, utilizing the male M5x0.8 rod thread for precise jaw attachment.
Is the Airtac SDA Ultra Thin Cylinder SDA12X30B the Right Cylinder?
When sizing this actuator, consider stepping up to the SDA16 if your application requires more force, as the 16mm bore provides a 100.5 N push at 0.5 MPa. Conversely, if you need the absolute minimum footprint, this 12mm bore is the smallest available in the SDA series. With a theoretical safe working load around 34 N (roughly 60% of the 56.5 N capacity), it is ideal for light-duty positioning. To configure correctly, confirm the 30mm stroke, M5x0.8 port, and the male M5x0.8 rod thread. Note that a standard cylinder drifts when air is lost; use an external rod lock or pilot-operated check valve if the load must be held.
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 SDA12X30B FAQ
This 12mm bore double-acting cylinder provides 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. The theoretical maximum push force is 12 kgf at 1.0 MPa.
No, this model uses a fixed NBR bumper to decelerate at stroke end, which is not an adjustable air cushion. Additionally, because this SKU lacks the -S magnet option, it cannot support magnetic reed or electronic switches.
