Airtac SDA Ultra Thin Cylinder SDA12X15B
The AirTAC Airtac SDA Ultra Thin Cylinder SDA12X15B is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm bore and 15mm 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 SDA12X15B
The AirTAC SDA12X15B is a double-acting single-rod compact cylinder engineered for tight spaces, delivering a push force of 56.5 N and a pull force of 42.4 N at 0.5 MPa. Its short riveted body drastically reduces axial mounting depth compared to conventional round-body units, making it ideal for dense machinery layouts. This specific SKU features a male M5x0.8 threaded piston rod for direct load coupling.
The 12 mm bore utilizes a hard-anodized inner wall and a fixed NBR bumper at each end to decelerate the stroke. Because this configuration lacks the -S magnet option, it cannot support magnetic reed or electronic switches. Operating at speeds from 30-500 mm/s, it provides a safe working load of roughly 34 N (about 60% of the 0.5 MPa push figure) and can vertically lift approximately 2.9 kg with a 2:1 safety margin.

Where the Airtac SDA Ultra Thin Cylinder SDA12X15B Is Used
PCB Edge Guiding
Uses the 56.5 N extend force to nudge printed circuit boards into alignment on a pick-and-place conveyor without damaging delicate traces.
Lab Dispenser Triggering
Short 15 mm stroke precisely taps the plunger of micro-fluidic valves in automated analytical chemistry equipment.
Small Part Ejection
Male M5x0.8 rod end pushes lightweight plastic components out of an injection mold cavity within a confined assembly cell.
Is the Airtac SDA Ultra Thin Cylinder SDA12X15B the Right Cylinder?
If your application requires less force, stepping down is not an option as this is the smallest available bore. Stepping up to the SDA16 increases your 0.5 MPa push force to 100.5 N. When ordering this model, confirm the 12 mm bore, 15 mm stroke, M5x0.8 port, male M5x0.8 rod thread (B option), and the absence of a sensor magnet. Note that a plain cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates it near the stroke end. For secure load holding, an external rod lock or pilot-operated check valve is required.
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 SDA12X15B FAQ
This 12 mm 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 force is 79.2 N. The theoretical maximum push force is 12 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and a speed range of 30-500 mm/s.
No adjustable air cushion is available; it relies on a fixed NBR bumper at each end to decelerate the stroke. For high energy impacts, slow the approach or add an external shock absorber. Additionally, this specific SKU lacks the -S magnet, so it cannot accommodate AirTAC reed or electronic switches.
