The AirTAC AirTAC SDA16X40H Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 40mm 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 SDA16X40H is a double-acting single-rod compact cylinder featuring a 16 mm bore and 40 mm stroke. It generates 100.5 N of push force and 86.4 N of pull force at 0.5 MPa. This H-series variant utilizes a fluororubber (FKM) seal for enhanced thermal stability and oil resistance compared to standard NBR. A 6 mm piston rod and M5x0.8 port are integrated to match the bore specifications.
Its riveted assembly significantly reduces axial mounting depth where a conventional round-body actuator will not fit. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note this specific SKU lacks a piston magnet, so position sensing is not supported without switching to the -S option.

Thread: PT standard. Related SDA-family variants: SSA (single-acting push), STA (single-acting pull), SDAD (double rod), SDAJ (adjustable stroke), SDAT (duplex), SDAW (duplex-end).
Provides the 100.5 N extension needed to press and secure small electronic panels during automated routing, where the FKM seal resists heat from high-speed spindles.
Cycles a 40 mm stroke to clamp thin polymer films against heated platens, with the compact riveted body fitting into narrow packaging machine frames.
Actuates a 6 mm rod to open and close precision fluid nozzles, offering reliable 86.4 N retract force at 0.5 MPa for consistent chemical metering.
When sizing this actuator, compare its 100.5 N push at 0.5 MPa against adjacent bores: the SDA12 offers 56.5 N for lighter duties, while the SDA20 provides 157.1 N if you need more thrust. A practical safe working load is approximately 60 N (about 60% of the 0.5 MPa figure), yielding a vertical lift capacity near 5.1 kg with a 2:1 safety margin. To order, confirm the 16 mm bore, 40 mm stroke, M5x0.8 port, female M3x0.5 rod thread, and the FKM seal. If your setup must hold a vertical load without live pressure, install an external rod lock or pilot-operated check valve, as the piston will drift and the bumper only slows it near the stroke end.
Quick checklist
At 0.5 MPa this 16 mm bore cylinder provides 100.5 N push and 86.4 N pull. At 0.7 MPa it provides 140.7 N push and 121 N pull. The theoretical maximum push is 21 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need the SDA16X40HS variant, which adds an internal magnet for sensing. Additionally, this model uses a fixed NBR bumper for end-stop deceleration, not an adjustable air cushion.
