Airtac SDA Ultra Thin Cylinder SDA12X15BH
The AirTAC Airtac SDA Ultra Thin Cylinder SDA12X15BH 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 SDA12X15BH
The AirTAC SDA12X15BH is a double-acting single-rod compact cylinder engineered for exceptionally tight axial spaces. A riveted assembly unites the barrel, rear cover, piston, and rod, drastically reducing mounting depth compared to conventional round-body units. Delivering 56.5 N of push force at 0.5 MPa, it features a hard-anodized bore and a two-way piston seal for reliable low-friction operation.
This specific configuration includes a male M5x0.8 threaded piston rod for secure load coupling and high-temperature fluororubber (FKM) seals for enhanced environmental resistance. The end stops rely on a fixed NBR bumper to decelerate the motion rather than an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot host AirTAC reed or electronic switches.

Where the Airtac SDA Ultra Thin Cylinder SDA12X15BH Is Used
PCB Pick-and-Place
Drives short 15 mm ejector strokes in surface-mount technology machines, where the compact riveted body saves valuable Z-axis height and the FKM seals resist localized heat.
Lab Dispensing Head
Actuates a micro-valve for chemical dosing, using the 56.5 N extend force to break viscous fluid surface tension without overwhelming delicate glass components.
Small Part Ejection
Pushes miniature plastic connectors out of an injection mold cavity, leveraging the male M5x0.8 rod thread to securely attach a custom soft-tip ejector pin.
Is the Airtac SDA Ultra Thin Cylinder SDA12X15BH the Right Cylinder?
Selecting this 12 mm bore unit makes sense when your envelope cannot accommodate longer cylinders and your payload is light—yielding a safe working load around 34 N (roughly 60% of the 56.5 N push at 0.5 MPa) or a vertical lift capacity of 2.9 kg with a 2:1 safety margin. If your application requires slightly more thrust, stepping up to the SDA16 provides 100.5 N at 0.5 MPa. When ordering, confirm the 15 mm stroke, M5x0.8 port, male M5x0.8 rod end, and FKM seal. Remember that a standard double-acting cylinder drifts if air pressure drops; use an external rod lock or pilot-operated check valve if you must hold a load safely mid-stroke.
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 SDA12X15BH FAQ
This 12 mm bore double-acting cylinder provides 56.5 N push and 42.4 N pull at 0.5 MPa, 79.2 N push and 59.4 N pull at 0.7 MPa, with a theoretical maximum push of 12 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, proof pressure is 1.5 MPa, and the speed range is 30-500 mm/s.
No adjustable air cushion is available; the cylinder uses a fixed NBR bumper at each end to decelerate the stroke. For high-energy cycles, slow the approach speed or add an external shock absorber. Additionally, this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches—the -S variant is required for position sensing.
