The AirTAC AirTAC SDA25X130S Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 130mm 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 SDA25X130S 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 integrates the barrel, rear cover, piston, and rod into a singularly short assembly, drastically reducing axial mounting depth where a conventional round-body unit would fail to fit.
Equipped with a built-in piston magnet (-S), this unit interfaces directly with AirTAC reed or electronic switches via the body grooves. The bore inner wall is hard-anodized for longevity, while end-stops rely on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to prevent impact damage.

Pushes lightweight cardboard cartons at 30-500 mm/s on a logistics sorting line, utilizing the 130 mm stroke to clear adjacent conveyor lanes effectively.
Maintains precise positioning of a packaging film roll arm, where the 245.4 N extend force provides adequate tension without tearing the wrapping material.
Ejects molded plastic parts from a vertical injection machine, taking advantage of the compact riveted body to fit within tight mold-clearance footprints.
When sizing this 25 mm bore actuator, evaluate your force requirements carefully: stepping down to the SDA20 yields 157.1 N of push at 0.5 MPa, whereas stepping up to the SDA32 provides 402.1 N. At 0.5 MPa, this model offers a safe working load of roughly 147 N (about 60 percent of its rated output) and can vertically lift approximately 12.5 kg with a 2:1 safety margin. To finalize your order, confirm the 130 mm stroke, M5x0.8 port, female M5x0.8 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 directional valve centers; the piston will drift, as the fixed bumper only decelerates the stroke end rather than locking the load. For vertical or suspended loads that must be secured without live pressure, incorporate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This 25 mm bore double-acting cylinder generates 245.4 N push and 206.2 N pull at 0.5 MPa, increasing to 343.6 N push and 288.6 N pull at 0.7 MPa. The theoretical maximum push force is 50 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and functions at speeds of 30-500 mm/s.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the piston near stroke completion; it is not an adjustable air cushion. Because this unit operates at the maximum standard stroke limit for the bore, if your cycle speed or moving mass is high, you should add an external shock absorber or slow the approach speed to prevent end-cap damage.
