About the Airtac SDA Ultra Thin Cylinder SDA12X15SB
The AirTAC SDA12X15SB is a double-acting single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly shrinks axial mounting depth compared to round-body units, yielding a 56.5 N push and 42.4 N pull at 0.5 MPa. The 12 mm bore utilizes a hard-anodized inner wall and a two-way piston seal for reliable low-friction motion.
This specific configuration includes a built-in piston magnet for AirTAC reed or electronic switches, fitting into the body's peripheral grooves. It features a male M5x0.8 threaded rod end for direct load coupling and a fixed NBR bumper at each end to absorb end-stop impact. Operating speed spans 30-500 mm/s, making it highly versatile for miniature pneumatic tasks.

Where the Airtac SDA Ultra Thin Cylinder SDA12X15SB Is Used
PCB Component Placement
Drives a small 15 mm pick-and-place stroke for electronic assembly heads, utilizing the 56.5 N push force to seat lightweight connectors without stressing the board.
Lab Dispenser Actuation
Moves a micro-pump or valve in analytical instruments where the compact riveted body saves axial depth, and the male M5x0.8 rod threads directly into the dispensing mechanism.
Small Part Ejection
Pushes miniature molded parts out of a testing fixture, relying on the built-in magnet and electronic switch to confirm the 15 mm ejection stroke is fully complete.
Is the Airtac SDA Ultra Thin Cylinder SDA12X15SB the Right Cylinder?
Selecting this 12 mm bore unit provides a safe working load around 34 N (60% of the 56.5 N @0.5 MPa figure) and a vertical lift capacity of roughly 2.9 kg with a 2:1 safety margin. If your application requires slightly more force, stepping up to the SDA16 yields 100.5 N push at 0.5 MPa. As the smallest standard bore, there is no smaller SDA option. Confirm your ordering essentials: 12 mm bore, 15 mm stroke, M5x0.8 port, built-in magnet (S), and male M5x0.8 rod thread (B).
Note that a plain SDA cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end; it does not function as a locking brake. For suspended loads, integrate an external rod lock or a pilot-operated check valve.
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 SDA12X15SB FAQ
This double-acting 12 mm bore cylinder generates a push of 56.5 N and a pull 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 between 0.15-1.0 MPa at speeds of 30-500 mm/s.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-energy cycles, slow the approach or add external shock absorbers. The included -S magnet works with AirTAC reed or electronic switches in the body grooves for position detection.
