The AirTAC AirTAC SDA25X65 Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 65mm 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 SDA25X65 is a double-acting single-rod compact cylinder engineered to deliver 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. Its riveted assembly unites the barrel, rear cover, piston, and rod into a highly shortened unit, drastically reducing the axial mounting footprint compared to conventional round-body designs. This space efficiency is critical when machine envelopes are tight.
This specific configuration features a 10 mm piston rod and an M5x0.8 port. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-speed approaches may require external shock absorbers. Because this SKU lacks the -S magnet option, it cannot host magnetic reed or electronic switches for position sensing.

Actuates the cutting head on an electronics assembly line, utilizing the 245.4 N push force to cleanly separate routed circuit panels within a compact equipment frame.
Folds minor corrugated box flaps prior to tape sealing, where the 65 mm stroke and 12.5 kg vertical lift capacity provide rapid, precise motion in tight packaging machinery.
Pushes lightweight parcels off a main transport belt, taking advantage of the shortened riveted body to fit between closely spaced conveyor rollers.
When sizing this actuator, consider stepping down to the SDA20, which provides 157.1 N of push at 0.5 MPa, or moving up to the SDA32, which yields 402.1 N at the same pressure. At 0.5 MPa, the SDA25X65 offers a safe working load of roughly 147 N (about 60% of its rated push) and can vertically lift approximately 12.5 kg with a 2:1 safety margin. To finalize your order, confirm the 25 mm bore, 65 mm stroke, M5x0.8 port, female rod-end thread (M5x0.8), and the absence of a sensor magnet.
Keep in mind that a standard double-acting cylinder does not hold its position if air pressure drops or the directional valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the stroke near its ends rather than locking the load. If your application requires strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder provides 245.4 N push and 206.2 N pull at 0.5 MPa. At 0.7 MPa, it yields 343.6 N push and 288.6 N pull. The theoretical maximum push force is 50 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa and a proof pressure of 1.5 MPa.
No, this specific SKU does not include a piston magnet, so it cannot support reed or electronic switches. You would need to specify the -S option code to enable position sensing. Additionally, it uses a fixed NBR bumper for end-stop deceleration, which is not an adjustable air cushion.
