The AirTAC AirTAC SDA25X80S Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 80mm 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 SDA25X80S is a double-acting, single-rod compact cylinder engineered for tight axial spaces. By utilizing a riveted assembly that merges the barrel, rear cover, piston, and rod, it achieves a remarkably short mounting depth compared to conventional round-body units. Delivering 245.4 N of push force at 0.5 MPa, it handles a safe working load of roughly 147 N (about 60% of its rated capacity) and can vertically lift approximately 12.5 kg with a 2:1 safety margin.
This specific configuration includes an 80 mm stroke and a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning external shock absorbers should be specified for high-energy cycling. The bore dictates an M5x0.8 air port and a 10 mm rod, available with either a female M5x0.8 or male M8x1.25 rod-end thread to suit your mechanical coupling.

Drives the Z-axis plunge on a printed circuit board depaneling router, where the shallow riveted body depth conserves gantry clearance and the 245.4 N push force cleanly cuts substrate materials.
Actuates a mechanical arm to tuck minor flaps on a continuous carton sealing line, utilizing the 80 mm stroke and magnetic switches to confirm flap position before tape application.
Provides vertical lift pressure on a metal strip straightener pad in a progressive stamping feed line, applying 206.2 N of retract force to maintain material tension without occupying excessive frame width.
When sizing this unit, evaluate your force requirements bidirectionally: stepping down to the SDA20 yields 157.1 N of push at 0.5 MPa, while stepping up to the SDA32 provides 402.1 N at the same pressure. Because an 80 mm stroke approaches the longer end of the standard range for this 25 mm bore, ensure your guiding mechanism prevents side-load stress on the 10 mm piston rod. To finalize your order, confirm the 25 mm bore, 80 mm stroke, M5x0.8 port, the required rod-end thread (female M5x0.8 or male M8x1.25), and the inclusion of the -S sensor magnet.
Keep in mind that a standard double-acting cylinder like this will not maintain its position if air pressure drops or the directional valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the end of stroke rather than acting as a positive lock. If your application demands strict load holding on air loss, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
At 0.5 MPa, this 25 mm bore cylinder outputs 245.4 N of push force and 206.2 N of pull force. At 0.7 MPa, push increases to 343.6 N and pull to 288.6 N. The theoretical maximum push capacity is 50 kgf at the 1.0 MPa operating pressure limit.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion; for high-speed cycling, add an external shock absorber. Furthermore, it does not hold its load if air is lost or the valve centers, requiring an external rod lock or pilot-operated check valve for fail-safe holding.
