The AirTAC AirTAC SDA25X120B Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 120mm 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 SDA25X120B 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 body design significantly reduces axial mounting depth compared to traditional round-body units, making it highly effective for machinery where space footprint is critical. This specific SKU features a male M8x1.25 piston rod end for secure mechanical load coupling.
This model operates at speeds between 30-500 mm/s and relies on a fixed NBR bumper at each end to decelerate the piston near stroke limits, rather than an adjustable air cushion. Because this configuration omits the -S magnet code, it cannot support AirTAC reed or electronic switches. Operating pressure ranges from 0.15 to 1.0 MPa, with a hard-anodized bore ensuring long service life.

Pushes light to medium cardboard cartons on a sorting line using its 245.4 N extend force, while the 120mm stroke clears the conveyor belt width completely.
Secures stretch film rolls in an automated wrapping station via the male M8x1.25 rod end, handling an approximate 12.5 kg vertical lift with a 2:1 safety margin.
Maintains yarn tension across a wide weaving machine bed, utilizing the compact riveted body to fit within narrow frame gaps where standard cylinders cannot mount.
When sizing this unit, evaluate stepping down to the SDA20 which provides 157.1 N of push at 0.5 MPa, or stepping up to the SDA32 which yields 402.1 N at the same pressure. Based on the 245.4 N output, a safe working load is approximately 147 N (around 60% capacity), translating to a vertical lift capability of roughly 12.5 kg with a 2:1 safety margin. Keep in mind a plain SDA body does not hold its load if air pressure drops or the valve is centered—the piston will drift, as the fixed bumper only decelerates near the stroke end and acts as neither a lock nor a brake. For suspended loads, utilize an external rod lock or pilot-operated check valve. To order, confirm the 25mm bore, 120mm stroke, M5x0.8 port, male M8x1.25 rod thread, and no magnet.
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 1.0 MPa. The operating pressure range is 0.15-1.0 MPa.
No, this specific SKU lacks the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. Additionally, it uses fixed NBR bumpers to decelerate the stroke end rather than an adjustable air cushion, so external shock absorbers may be needed for high-speed operations.
