The AirTAC SDA12X70 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 SDA12X70 is a double-acting single-rod compact cylinder engineered for tight spaces, delivering 56.5 N of push force at 0.5 MPa. Because the 70 mm stroke exceeds the 60 mm standard maximum for this 12 mm bore, this specific unit is a non-standard, made-to-order configuration. The riveted body assembly drastically reduces axial mounting depth compared to conventional round-body units, making it ideal for dense machinery layouts.
This model features a 6 mm piston rod and an M5x0.8 port. It relies on a fixed NBR bumper at each end to decelerate the stroke end rather than an adjustable air cushion. Without the -S option, this SKU lacks a piston magnet and cannot support magnetic sensing. Operating speed ranges from 30-500 mm/s, and the hard-anodized bore ensures durable performance within the -20 to +70 C temperature range.

Cycles delicate printed circuit boards out of test fixtures using a measured 56.5 N push, where the short riveted body prevents interference with adjacent test probes.
Actuates small fluidic diverter gates in automated analyzers, offering a 2.9 kg vertical lift margin while fitting into compact diagnostic equipment housings.
Pushes lightweight plastic or metal components into sorting chutes on high-speed assembly lines, operating at up to 500 mm/s within a minimal axial footprint.
When sizing this actuator, evaluate your force margins carefully. If your application demands greater thrust, stepping up to the SDA16 provides 100.5 N of push at 0.5 MPa. As the smallest available bore in the series, there is no smaller standard option, so loads requiring less than 34 N should rely on precise pressure regulation instead.
Confirm your ordering essentials: 12 mm bore, 70 mm non-standard stroke, M5x0.8 port, female M3x0.5 rod thread, and no sensor magnet. Note that a plain SDA cylinder does not hold its position or load when air is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates it near the stroke end. For applications requiring position holding without live pressure, an external rod lock or pilot-operated check valve is required.
Quick checklist
This 12 mm bore cylinder generates a push of 56.5 N and a pull of 42.4 N at 0.5 MPa. At 0.7 MPa, the push increases to 79.2 N. The theoretical maximum push is 12 kgf at the maximum operating pressure of 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot support reed or electronic switches. You must order the -S variant for sensing capabilities. Additionally, it uses a fixed NBR bumper rather than an adjustable air cushion, so external shock absorbers may be needed for high-energy loads.
