The AirTAC AirTAC SDA25X25N Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 25mm 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 SDA25X25N is a double-acting single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly significantly reduces axial mounting depth compared to conventional round-body units. Delivering 245.4 N of push force at 0.5 MPa, it features a hard-anodized 25 mm bore and a 10 mm piston rod.
This model relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion. Because this specific SKU lacks the -S magnet option, it cannot support magnetic reed or electronic switches. The M5x0.8 port ensures straightforward pneumatic integration.

Actuates the cutting head support on an electronics depaneling machine, utilizing the 25 mm stroke and 245.4 N force to maintain precise routing depth.
Folds minor flaps on small product cartons in a continuous packaging line, where the short riveted body minimizes interference with adjacent conveyor belts.
Provides a repeatable mechanical stop for a liquid dispensing nozzle in automated laboratory equipment, handling low-inertia loads safely within the 30-500 mm/s speed range.
When sizing this 25 mm bore unit, consider stepping down to the SDA20 which provides 157.1 N of push at 0.5 MPa, or moving up to the SDA32 which yields 402.1 N at the same pressure. For your ordering essentials, confirm the 25 mm bore, 25 mm stroke, M5x0.8 port, female rod-end thread, and the absence of a piston magnet. A safe working load is approximately 147 N, allowing a vertical lift of about 12.5 kg with a 2:1 safety margin.
Keep in mind that a standard compact cylinder will not hold a load if air pressure drops or the valve is centered; the piston drifts until the bumper catches it. If your application requires position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting 25 mm bore cylinder generates 245.4 N push and 206.2 N pull at 0.5 MPa. At 0.7 MPa, it provides 343.6 N push and 288.6 N pull. The theoretical maximum push force is 50 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, this specific SKU does not include the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify the -S option variant to utilize the magnetic switch grooves molded around the body.
