The AirTAC AirTAC SDA25X90 Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 90mm 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 SDA25X90 is a double-acting single-rod compact cylinder engineered for tight axial mounting spaces. It provides 245.4 N of push force and 206.2 N of pull force at 0.5 MPa, utilizing a hard-anodized bore and a two-way piston seal for reliable pneumatic actuation. This specific SKU lacks a piston magnet and therefore cannot support magnetic position sensing.
Featuring a 90 mm stroke and a 10 mm piston rod, this model relies on a fixed NBR bumper at each end to decelerate the end stop. Because it is not an adjustable air cushion, operators should slow the approach or add external shock absorbers for high-energy loads. The riveted body design drastically reduces overall length compared to traditional round-body cylinders, making it ideal for minimizing machine footprint.

Actuates a routing flap on a logistics sorting line, utilizing the 90 mm stroke to push parcels cleanly into secondary chutes at high speeds.
Drives the mechanical arms that fold minor flaps on a continuous packaging conveyor, fitting neatly within the narrow frame of the sealing machine.
Pushes processed test tubes out of a centrifuge carousel, where the short riveted body saves valuable vertical space inside the diagnostic equipment.
When sizing this actuator, stepping down to the SDA20 yields 157.1 N of push force at 0.5 MPa, while stepping up to the SDA32 provides 402.1 N at the same pressure. At 0.5 MPa, the safe working load is approximately 147 N (about 60 percent of the 245.4 N figure), allowing a vertical lift of roughly 12.5 kg with a 2:1 safety margin. To confirm your ordering essentials for this model: specify the 25 mm bore, 90 mm stroke, M5x0.8 port, female M5x0.8 rod thread (or male M8x1.25 if needed), and note that no magnet is present.
Keep in mind that a plain SDA cylinder does not hold its position or load when air pressure is lost or the valve is centered. The piston will drift, and the fixed NBR bumper only decelerates it near the stroke end rather than acting as a lock. If your application requires a held load without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting single-rod cylinder generates a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa. At 0.7 MPa, the push force is 343.6 N and the pull force is 288.6 N. The theoretical maximum push force is 50 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 to order the SDA25X90S variant to enable magnetic position sensing. Additionally, it uses a fixed NBR bumper rather than an adjustable air cushion.
