The AirTAC AirTAC SDA25X25H Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 25mm 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 SDA25X25H is a double-acting single-rod compact cylinder featuring a 25 mm bore and 25 mm stroke. It generates 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. This specific SKU uses fluororubber (FKM) seals, providing enhanced resistance to higher temperatures and oily environments compared to the standard NBR configuration.
The short riveted body significantly reduces axial mounting depth, making it ideal for tight machine footprints where a standard round-body cylinder cannot fit. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Without a piston magnet, this unit cannot host magnetic switches; adding the -S option enables reed or electronic switch sensing.

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).
Deploys short-stroke probing arms in machining centers where the FKM seals withstand elevated ambient heat from nearby spindles.
Applies the 245.4 N push force to clamp heated sealing jaws on packaging lines, fitting neatly into narrow frame gaps.
Drives sorting flaps on conveyor systems; the compact riveted body minimizes protrusion into adjacent product lanes.
When sizing this actuator, evaluate your neighbours: the SDA20 provides 157.1 N of push at 0.5 MPa for lighter duties, while the SDA32 steps up to 402.1 N for heavier loads. At 0.5 MPa, the SDA25X25H offers a safe working load of roughly 147 N (about 60% of its 245.4 N capacity) and can vertically lift approximately 12.5 kg with a 2:1 safety margin. Confirm your ordering essentials: 25 mm bore, 25 mm stroke, M5x0.8 port, female rod-end thread, and FKM seals. Note that a plain cylinder drifts when air is lost or the valve is centred; the fixed bumper only decelerates near stroke end and does not act as a lock. To hold a load without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
This 25 mm bore double-acting cylinder provides 245.4 N push and 206.2 N pull at 0.5 MPa, 343.6 N push and 288.6 N pull at 0.7 MPa, with a theoretical maximum push of 50 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa.
No, this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches. You would need the -S option for sensing. Additionally, it uses fixed NBR bumpers for end-stop deceleration, not an adjustable air cushion.
