The AirTAC AirTAC SDA25X110S Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 110mm 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 SDA25X110S is a double-acting, single-rod compact cylinder engineered to deliver a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa. Its riveted assembly significantly reduces axial mounting depth compared to conventional round-body units, making it highly effective for machinery where space footprint is critical. The bore is hard-anodized and relies on a two-way piston seal for efficient operation.
This specific configuration includes a 110 mm stroke and a built-in piston magnet (the S option) for use with AirTAC reed or electronic switches housed in the body grooves. End-stop deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Operating at speeds between 30 and 500 mm/s, it features a 10 mm piston rod and an M5x0.8 air port.

Actuates a routing flap on a logistics sorting line, utilizing the 110 mm stroke to shift parcels between adjacent belts with precise timing.
Drives the mechanical arms that fold minor flaps on a case erector, fitting easily within the tight axial constraints of the packaging frame.
Pushes processed test tubes out of a centrifuge carousel, relying on the built-in magnet to confirm the extended position via a solid-state sensor.
When sizing this actuator, evaluate your force margins carefully. Stepping down to the SDA20 provides 157.1 N of push at 0.5 MPa, while moving up to the SDA32 yields 402.1 N. The SDA25X110S provides 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. To order, confirm the 25 mm bore, 110 mm stroke, M5x0.8 port, female rod-end thread, and the required magnetic sensor option.
Keep in mind that a standard compact cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift. The fixed NBR bumper only decelerates the stroke near the end limits and does not function as a locking brake. If your application requires absolute load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 245.4 N and the pull force is 206.2 N. At 0.7 MPa, the push force is 343.6 N. The theoretical maximum push force is 50 kgf at the maximum operating pressure of 1.0 MPa.
No, the SDA25X110S uses a fixed NBR bumper at each end to decelerate the piston. It is not an adjustable air cushion. For high-energy or high-speed cycles, you should add an external shock absorber or reduce the approach speed.
