The 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.

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.
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.
