The AirTAC AirTAC SDA25X5N 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 SDA25X5N is a double-acting single-rod compact cylinder engineered for extremely tight axial spaces. Operating at 0.5 MPa, it generates 245.4 N of push force and 206.2 N of pull force, making it suitable for short-distance positioning tasks.
This model features a 10 mm piston rod and an M5x0.8 air port. It relies on a fixed NBR bumper at each end to decelerate the stroke end, which is not an adjustable air cushion. This specific SKU lacks a piston magnet, so it cannot support magnetic sensing without upgrading to the -S variant.

Provides a rapid 5 mm ejection stroke to push finished circuit boards out of testing fixtures without consuming valuable vertical machine footprint.
Delivers 245.4 N of clamping pressure at 0.5 MPa to secure small electronic components during ultrasonic welding processes.
Executes a tiny 5 mm tucking motion to fold minor corrugated box flaps precisely before tape sealing on high-speed packaging lines.
When sizing this actuator, stepping down to the SDA20 reduces the 0.5 MPa push force to 157.1 N, while stepping up to the SDA32 increases it to 402.1 N. Based on the 245.4 N output, the safe working load is approximately 147 N, allowing a vertical lift of roughly 12.5 kg with a 2:1 safety margin. To finalize your order, confirm the 25 mm bore, 5 mm stroke, M5x0.8 port, female rod thread, and the absence of a sensor magnet. If the application must hold a load without live pressure, note that the piston will drift on air loss, requiring an external rod lock or pilot-operated check valve.
Quick checklist
This double-acting cylinder provides 245.4 N push and 206.2 N pull at 0.5 MPa, or 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 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to select the -S option code to add a magnet for sensing. Additionally, it uses a fixed NBR bumper rather than an adjustable cushion, so external shock absorbers are recommended for high-energy impacts.
