The AirTAC AirTAC SDA12X70B Compact Cylinder | 12mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø12mm bore and 70mm 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 SDA12X70B is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly significantly reduces axial mounting depth compared to round-body units, yielding a theoretical push of 56.5 N and pull of 42.4 N at 0.5 MPa. This specific configuration features a 70 mm stroke, which exceeds the 60 mm standard maximum for this 12 mm bore, making it a non-standard, made-to-order item.
Equipped with a male M5x0.8 threaded piston rod, this model provides a robust mechanical coupling for your load. Because this SKU lacks the -S suffix, it has no piston magnet and cannot support position sensing. End-of-travel deceleration is handled strictly by fixed NBR bumpers rather than adjustable air cushions, so external shock absorbers are advised for high-energy cycles.

Pushes lightweight printed circuit boards into alignment fixtures using a 34 N safe working load, where the short riveted body conserves valuable routing space.
Drives a small fluid nozzle across a 70 mm travel path, benefiting from the 2.9 kg vertical lift capacity to raise and lower delicate dosing heads.
Cycles at 30-500 mm/s to eject miniature plastic components from an injection mold, relying on the fixed NBR bumper to absorb the end stop.
When sizing this actuator, note that the 56.5 N push force at 0.5 MPa translates to a safe working load of roughly 34 N (about 60% capacity) or a vertical lift of approximately 2.9 kg with a 2:1 safety margin. If your application requires slightly more thrust, the adjacent SDA16 bore provides 100.5 N of push at 0.5 MPa. Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. To hold a load securely without live pressure, you must integrate an external rod lock or a pilot-operated check valve. To order, confirm the 12 mm bore, 70 mm non-standard stroke, M5x0.8 port, male M5 rod thread, and no magnet.
Quick checklist
This 12 mm bore double-acting cylinder provides a push of 56.5 N and a pull of 42.4 N at 0.5 MPa. At 0.7 MPa, the push is 79.2 N. The theoretical maximum push force is 12 kgf at 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot support reed or electronic switches. You would need the -S option variant to utilize the magnetic switch grooves around the body.
