Airtac SDA Ultra Thin Cylinder SDA12X15
The AirTAC SDA Ultra Thin Cylinder SDA12X15 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 SDA12X15
The AirTAC SDA12X15 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 riveted assembly merges the barrel, rear cover, piston, and rod to drastically reduce axial mounting depth compared to round-body alternatives. The 12 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable low-friction operation.
This specific configuration uses an M5x0.8 port and a 6 mm piston rod with a female M3x0.5 thread end. Because this SKU lacks the -S suffix, it has no internal piston magnet and cannot support position sensing. End-of-travel deceleration is handled strictly by fixed NBR bumpers rather than an adjustable air cushion, meaning external shock absorbers should be considered for high-energy loads.

Where the Airtac SDA Ultra Thin Cylinder SDA12X15 Is Used
PCB Component Placement
Drives a small pick-and-place head for surface mount electronics assembly, utilizing the 56.5 N extend force to push lightweight actuators without overwhelming delicate boards.
Lab Dispenser Triggering
Actuates micro-valves on automated chemical dispensing stations where the 15 mm stroke and compact footprint fit easily within crowded benchtop enclosures.
Small Part Ejection
Pushes tiny plastic molded parts out of an injection mold cavity, relying on the fixed NBR bumper to absorb the end-stop impact within the 30-500 mm/s speed range.
Is the Airtac SDA Ultra Thin Cylinder SDA12X15 the Right Cylinder?
If your application requires slightly more force, stepping up to the SDA16 increases the push output to 100.5 N at 0.5 MPa. When ordering, confirm the 15 mm stroke, M5x0.8 port, female M3x0.5 rod thread, and the absence of a sensor magnet.
Keep in mind that a standard double-acting cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift. If your machinery demands fail-safe load holding, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
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 SDA12X15 FAQ
This double-acting 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 increases to 79.2 N. The theoretical maximum push 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, this specific SKU does not include the -S option, meaning it lacks the internal piston magnet required for sensing. To use AirTAC reed or electronic switches in the body grooves, you must order the SDA12X15S variant. Additionally, this model uses fixed NBR bumpers rather than adjustable cushions.
