The AirTAC AirTAC SDA25X140 Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 140mm 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 SDA25X140 is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly significantly reduces overall length compared to round-body units, while delivering 245.4 N of push force at 0.5 MPa. This specific 140 mm stroke exceeds the 130 mm standard limit, making it a non-standard, made-to-order configuration.
This model features a 10 mm piston rod and an M5x0.8 port. It relies on a fixed NBR bumper at each end to decelerate the stroke end, rather than an adjustable air cushion. Without the -S option, this SKU lacks a piston magnet and cannot accept magnetic switches.

Pushes light cardboard cartons between sorting lanes on a logistics conveyor, utilizing the 140 mm travel to clear adjacent guide rails without excessive axial bulk.
Advances shrink-wrap material on a packaging line, where the compact riveted body fits neatly between narrow machine frames and the fixed NBR bumper handles repetitive end-stops.
Ejects molded plastic components from a light-duty press, using the 245.4 N extend force to push parts into a collection chute at a safe working load of 147 N.
For sizing context, stepping down to the SDA20 yields 157.1 N push at 0.5 MPa, while stepping up to the SDA32 provides 402.1 N. Based on the 245.4 N output, your safe working load is roughly 147 N (about 60% capacity), translating to a 12.5 kg vertical lift with a 2:1 safety margin. Because this 140 mm stroke exceeds the 130 mm standard maximum for this bore, it requires a made-to-order request.
When ordering, confirm the 25 mm bore, 140 mm stroke, M5x0.8 port, female rod-end thread, and the absence of a sensor magnet. Note that a plain SDA cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift. For suspended or vertical loads, integrate an external rod lock or pilot-operated check valve.
Quick checklist
This 25 mm bore double-acting cylinder provides 245.4 N push and 206.2 N pull at 0.5 MPa, and 343.6 N push at 0.7 MPa. The theoretical maximum push is 50 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed of 30-500 mm/s.
No, this specific SKU does not include the -S option, meaning it lacks a piston magnet and cannot be used with reed or electronic switches. You would need to specify the SDA25X140S variant to enable sensor groove functionality.
