About the Airtac SDA Ultra Thin Cylinder SDA25X50
The AirTAC SDA25X50 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 assembly significantly reduces axial mounting depth compared to conventional round-body units, making it ideal for machinery where space savings are critical. The hard-anodized bore ensures smooth, low-friction operation throughout the 50 mm stroke.
This model features a 10 mm piston rod and an M5x0.8 air port. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-energy cycles. Note that this specific SKU lacks a piston magnet, so it cannot support magnetic position sensing without upgrading to the -S option.

Where the Airtac SDA Ultra Thin Cylinder SDA25X50 Is Used
Carton Flap Folding
Drives the short folding arms on automated packaging lines to tuck corrugated carton flaps prior to tape sealing.
Sorter Diverter Gate
Actuates routing gates on package conveyor systems, providing swift 50 mm redirection strokes for parcel sorting.
PCB Edge Clamping
Secures circuit board panels within CNC drilling fixtures, utilizing the compact body to minimize Z-axis interference.
Is the Airtac SDA Ultra Thin Cylinder SDA25X50 the Right Cylinder?
When sizing this unit, evaluate your force margins carefully. Stepping down to the SDA20 reduces the 0.5 MPa push capacity to 157.1 N, while stepping up to the SDA32 increases it to 402.1 N.
Confirm your ordering essentials: 25 mm bore, 50 mm stroke, M5x0.8 port, female rod-end thread (M5x0.8), and no magnet. Because this is a standard double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered—the piston drifts, and the fixed bumper only decelerates near the stroke end. For static holding, 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 SDA25X50 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 force is 343.6 N. The theoretical maximum push force is 50 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed of 30-500 mm/s.
No, this specific SKU does not include a piston magnet. To use AirTAC reed or electronic switches, you must select the SDA25X50S variant, which includes the built-in magnetic ring for position sensing.
