About the Airtac SDA Ultra Thin Cylinder SDA25X45
The AirTAC SDA25X45 is a double-acting single-rod compact cylinder delivering a 245.4 N push and 206.2 N pull at 0.5 MPa. Its riveted assembly keeps axial length minimal, saving valuable mounting depth where a conventional round-body unit would protrude. The hard-anodized 25 mm bore operates at speeds from 30-500 mm/s.
This specific SKU lacks a piston magnet, meaning it cannot host AirTAC reed or electronic switches. End-stopping relies strictly on a fixed NBR bumper rather than an adjustable air cushion, so high-energy cycles may require an external shock absorber to prevent impact wear.

Where the Airtac SDA Ultra Thin Cylinder SDA25X45 Is Used
Package Diverting Gate
Actuates a routing flap on a logistics sorting line, using the 45 mm stroke to push parcels smoothly onto secondary chutes without taking up frame width.
PCB Edge Clamping
Secures circuit boards during an automated soldering process, applying 245.4 N of clamping pressure at 0.5 MPa while fitting within tight machine enclosures.
Carton Flap Folding
Drives a mechanical arm to tuck top flaps on a packaging conveyor, where the short riveted body prevents collision with adjacent tooling.
Is the Airtac SDA Ultra Thin Cylinder SDA25X45 the Right Cylinder?
Selecting this 25 mm bore offers a safe working load near 147 N (roughly 60 percent of its 0.5 MPa output) and a vertical lift capacity around 12.5 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA20 provides 157.1 N at 0.5 MPa. Conversely, demanding jobs can step up to the SDA32 which yields 402.1 N at 0.5 MPa. To finalize your order, confirm the 45 mm stroke, M5x0.8 port, female M5x0.8 rod thread, and that no magnet is needed.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure drops or the valve is centered—the piston drifts until the bumper catches it. For vertical or suspended loads that must remain fixed during air loss, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short-body depth vs. a round-body cylinder
- ✓ Port/thread type (PT)
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
- ✓ Side load — avoid on a compact rod
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the short piston rod.
- check Very long strokes are unsuitable for the compact body.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDA Ultra Thin Cylinder SDA25X45 FAQ
At 0.5 MPa, the push force is 245.4 N and the pull force is 206.2 N. At 0.7 MPa, the push is 343.6 N and the pull is 288.6 N. The theoretical maximum push is 50 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa and a speed range of 30-500 mm/s.
No, this specific SKU is built without a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify the -S option code to add a magnet for sensing. Additionally, it uses a fixed NBR bumper at each end rather than an adjustable air cushion.
