Airtac SDA Ultra Thin Cylinder SDA12X15H
The AirTAC Airtac SDA Ultra Thin Cylinder SDA12X15H 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 SDA12X15H
The AirTAC SDA12X15H 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 round-body alternatives, making it ideal for dense machinery layouts. This specific H variant utilizes a fluororubber (FKM) seal for enhanced thermal and oil resistance.
It features a 6 mm piston rod and an M5x0.8 port. Instead of an adjustable air cushion, the unit relies on a fixed NBR bumper at each end to decelerate the stroke. Note that this SKU lacks a piston magnet, so it cannot support magnetic sensing; adding the -S option enables reed or electronic switch integration.

Where the Airtac SDA Ultra Thin Cylinder SDA12X15H Is Used
PCB Pick & Place
Drives small gripper jaws in electronics assembly lines, where the 34 N safe working load easily handles lightweight components and the compact body fits between dense routing channels.
Lab Dispenser Actuation
Actuates micro-valves for chemical dosing, leveraging the FKM seal to withstand higher temperature environments and aggressive media without degrading.
Small Part Ejection
Pushes miniature molded plastic parts out of a machining fixture, utilizing the 15 mm stroke and fixed NBR bumpers to ensure consistent ejection without complex shock absorption.
Is the Airtac SDA Ultra Thin Cylinder SDA12X15H the Right Cylinder?
For this 12 mm bore, the theoretical push force is 56.5 N at 0.5 MPa, yielding a safe working load of roughly 34 N (about 60% of capacity) or a vertical lift of approximately 2.9 kg with a 2:1 safety margin. If your application requires slightly more power, stepping up to the SDA16 provides 100.5 N of push at 0.5 MPa. Because this is the smallest available bore in the series, there is no smaller standard option to step down to.
When ordering, confirm the 12 mm bore, 15 mm stroke, M5x0.8 port, female M3x0.5 rod thread, and the FKM seal option. Remember that a plain compact 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 near the end of travel. To maintain position, 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 SDA12X15H 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 and 1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot support AirTAC reed or electronic switches. You would need to specify the -S option to add a magnet for sensing. Additionally, it uses a fixed NBR bumper rather than an adjustable air cushion, so external shock absorbers may be required for high-energy loads.
