About the Airtac SDA Ultra Thin Cylinder SDA12X25
The AirTAC SDA12X25 is a double-acting single-rod compact cylinder delivering 56.5 N of push force at 0.5 MPa. Its riveted assembly joins the barrel, rear cover, piston, and rod into an ultra-short unit, drastically reducing axial mounting depth where a round-body component would not fit. The 12 mm bore features a hard-anodized inner wall and a two-way piston seal for low-friction operation.
This specific SKU lacks a piston magnet and therefore cannot support sensing switches. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-speed approaches may require external shock absorption. Operating speed spans 30-500 mm/s, and the 6 mm rod uses an M5x0.8 port with a female M3x0.5 rod-end thread.

Where the Airtac SDA Ultra Thin Cylinder SDA12X25 Is Used
PCB Probe Testing
Drives delicate test pins onto printed circuit boards, utilizing the 56.5 N push force and short 25 mm stroke to verify electrical connections within dense automated testing fixtures.
Lab Dispense Valving
Actuates micro-dispense nozzles for chemical reagents, where the compact riveted body minimizes axial footprint and the 6 mm rod provides precise fluid flow control.
Micro-Part Ejection
Pushes small plastic or metal components out of machining centers, relying on the fixed NBR bumper to absorb the end stop without requiring bulky external cushioning.
Is the Airtac SDA Ultra Thin Cylinder SDA12X25 the Right Cylinder?
For lower force requirements, this 12 mm bore is the smallest available option in the series. If your application demands more power, stepping up to the SDA16 increases the 0.5 MPa push force to 100.5 N.
Because a standard double-acting cylinder does not hold its position when air pressure is lost or the valve is centered, the piston will drift and the fixed bumper only decelerates it near the stroke end. To suspend a load securely without live pressure, integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 12 mm bore, 25 mm stroke, M5x0.8 port, female rod thread, and no magnet.
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 SDA12X25 FAQ
This double-acting 12 mm bore 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 is 12 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa with a speed range of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot support sensing. To use AirTAC reed or electronic switches in the body grooves, you must specify the -S option (SDA12X25S) when ordering to add the internal magnet.
