The AirTAC AirTAC SDA12X65 Compact Cylinder | 12mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm bore and 65mm 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.
The AirTAC SDA12X65 is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. By utilizing a riveted assembly that merges the barrel, rear cover, piston, and rod, it achieves a remarkably short axial length where round-body units fail to fit. Operating at 0.5 MPa, it generates 56.5 N of push force and 42.4 N of pull force, yielding a safe working load of roughly 34 N (about 60% of the 0.5 MPa push figure) and a vertical lift capacity near 2.9 kg with a 2:1 safety margin.
This specific configuration features a 65 mm stroke, which exceeds the 60 mm maximum standard stroke for a 12 mm bore, making it a non-standard, made-to-order item. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-speed approaches may require external shock absorption. The 6 mm piston rod utilizes a female M3x0.5 thread, and because this SKU lacks the -S magnet option, it cannot host magnetic reed or electronic switches.

Shifts delicate printed circuit boards into alignment within a pick-and-place machine using a 34 N safe working load, fitting neatly into shallow routing bays.
Drives a micro-valve on an automated fluid dispensing station, where the 2.9 kg vertical lift capacity easily manages the light dispenser head assembly.
Pushes miniature plastic connectors out of an injection mold cavity, relying on the 56.5 N extend force to break the parts free cleanly.
When sizing this 12 mm bore actuator, consider stepping up to the SDA16, which provides 100.5 N of push at 0.5 MPa if your application requires more force. As the smallest available bore in the series, there is no smaller SDA option to step down to. Keep in mind that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the piston near the stroke end and does not function as a locking brake. If your process demands position holding without live pressure, incorporate an external rod lock or a pilot-operated check valve. To order, confirm the 12 mm bore, 65 mm non-standard stroke, M5x0.8 port, female rod thread, and no magnet.
Quick checklist
This 12 mm bore cylinder delivers 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. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa, and the speed range is 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify the -S option (e.g., SDA12X65S) to enable sensor mounting in the body grooves. Additionally, because the 65 mm stroke exceeds the 60 mm standard maximum for this bore, it is manufactured as a non-standard, made-to-order item.
