Airtac SDA Ultra Thin Cylinder SDA12X10B
The AirTAC Airtac SDA Ultra Thin Cylinder SDA12X10B is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm bore and 10mm 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 SDA12X10B
The AirTAC SDA12X10B is a double-acting, single-rod compact cylinder engineered for tight axial spaces. Operating at 0.5 MPa, it generates a 56.5 N push force and a 42.4 N pull force. This specific SKU features a male M5x0.8 threaded piston rod end for direct load coupling, replacing the standard female M3x0.5 thread. The bore is hard-anodized, and the body is riveted to minimize overall length.
Because this configuration lacks the -S magnet option, it cannot accept AirTAC reed or electronic switches. End-of-travel deceleration is handled strictly by a fixed NBR bumper rather than an adjustable air cushion. Operating speed spans 30-500 mm/s, making it suitable for rapid, short-throw tasks within a 0.15-1.0 MPa pressure range.

Where the Airtac SDA Ultra Thin Cylinder SDA12X10B Is Used
PCB Probe Testing
Drives delicate test probes against printed circuit boards with a precise 10 mm travel, utilizing the 56.5 N extend force without overwhelming the electronic components.
Small Part Ejection
Pushes lightweight plastic molded parts out of a machining fixture, where the male M5x0.8 rod threads directly into a custom ejector pin for secure attachment.
Lab Dispenser Actuation
Toggles a micro-valve on an automated fluid dispensing head, taking advantage of the short 12 mm bore riveted body to fit densely packed laboratory automation equipment.
Is the Airtac SDA Ultra Thin Cylinder SDA12X10B the Right Cylinder?
When sizing this 12 mm bore actuator, stepping up to the SDA16 provides a higher 100.5 N push at 0.5 MPa for heavier resistance. As the smallest available SDA bore, this model offers a highly compact footprint but requires careful load management; a safe working load is approximately 34 N (about 60% of the 56.5 N figure), allowing a vertical lift of roughly 2.9 kg with a 2:1 safety margin. To finalize your order, confirm the 10 mm stroke, M5x0.8 port, male M5x0.8 rod thread, and the absence of a sensor magnet. Note that this unit will not hold a load if air pressure drops; the piston drifts until the bumper arrests it, so an external rod lock or pilot-operated check valve is required for fail-safe positioning.
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 SDA12X10B FAQ
This 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 is 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.
No adjustable air cushion is available; end stops rely solely on a fixed NBR bumper. If you need position feedback, you must select the -S variant, as this specific SKU lacks the piston magnet required for AirTAC reed or electronic switches.
