The AirTAC AirTAC SDA25X5S Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 5mm 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 SDA25X5S is a double-acting, single-rod compact cylinder engineered for minimal axial mounting depth. By utilizing a riveted body assembly, it achieves a significantly shorter footprint than conventional round-body actuators, making it ideal for tight machine layouts. This specific 25mm bore variant generates 245.4 N of push force and 206.2 N of pull force at 0.5 MPa, operating efficiently across a 30-500 mm/s speed range.
Equipped with a built-in piston magnet (-S), this model supports direct mounting of AirTAC reed or electronic switches along the body grooves for precise end-of-stroke detection. The unit features a 10mm piston rod, an M5x0.8 air port, and relies on a fixed NBR bumper at each end to decelerate the stroke. Because this 5mm stroke is so brief, impact energy is minimal, though the stopping mechanism remains non-adjustable.

Provides a rapid 5mm ejection stroke to push finished circuit boards out of testing fixtures without consuming valuable vertical machine envelope.
Drives the short closing motion of sealing jaws in vertical form-fill-seal equipment, delivering 245.4 N to crimp packaging material securely.
Actuates a diverter flap in a high-speed conveyor sorting station, using the integrated magnet to confirm gate position for electronic switch feedback.
When sizing this actuator, consider stepping down to the SDA20, which provides 157.1 N of push force at 0.5 MPa, or moving up to the SDA32, which yields 402.1 N at the same pressure. For this SDA25X5S configuration, the safe working load is approximately 147 N (about 60% of the 245.4 N figure), translating to a vertical lift capacity of roughly 12.5 kg with a 2:1 safety margin. Ensure your ordering essentials match the 25mm bore, 5mm stroke, M5x0.8 port, female rod-end thread, and the required magnetic piston.
Keep in mind that a standard compact cylinder does not hold its position if air pressure is lost or the directional valve is centered; the piston will drift. The fixed NBR bumper only decelerates the load near the stroke end and does not function as a mechanical lock. 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 25mm 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 force is 50 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa and runs at speeds of 30-500 mm/s.
No, it uses a fixed NBR bumper at each end to absorb impact. This bumper is not field-adjustable and does not act as a brake. For high-energy cycles, you should slow the approach speed or add an external shock absorber.
