Airtac SDA Ultra Thin Cylinder SDA25X25
The AirTAC SDA Ultra Thin Cylinder SDA25X25 is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 25mm 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.

About the Airtac SDA Ultra Thin Cylinder SDA25X25
The AirTAC SDA25X25 is a double-acting single-rod compact cylinder delivering a 245.4 N push at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston and rod into a highly shortened unit, drastically reducing axial mounting depth compared to round-body alternatives. The hard-anodized bore and two-way piston seal ensure reliable service within the 0.15-1.0 MPa operating range.
This specific SKU lacks a piston magnet and therefore cannot support magnetic sensing; adding the -S option enables reed or electronic switches in the body grooves. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion.

Where the Airtac SDA Ultra Thin Cylinder SDA25X25 Is Used
PCB Drill Spindle Gating
Cycles a drill head guide into position on a printed circuit board routing machine, utilizing the 245.4 N extend force within a tight 25 mm stroke.
Blister Pack Lid Press
Applies brief downward pressure to seal pharmaceutical blister packs, where the short riveted body minimizes footprint on the packaging carousel.
Sorter Diverter Arm
Pushes small parcels laterally on a logistics belt using a 12.5 kg vertical lift capacity, fitting easily between tight conveyor frame gaps.
Is the Airtac SDA Ultra Thin Cylinder SDA25X25 the Right Cylinder?
When sizing this 25 mm bore actuator, evaluate your force needs carefully. Stepping down, the SDA20 provides 157.1 N push at 0.5 MPa; stepping up, the SDA32 yields 402.1 N push at 0.5 MPa. Confirm your ordering essentials: 25 mm bore, 25 mm stroke, M5x0.8 port, female rod thread (M5x0.8), and no magnet. A male rod end requires the B suffix.
Remember that a standard compact cylinder drifts when air pressure is lost or the valve is centered. The fixed NBR bumper only softens the impact near the stroke end and does not function as a locking brake. If your mechanism must hold a vertical load without live pressure, 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 SDA25X25 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, with a proof pressure of 1.5 MPa.
No, this specific SKU does not include a piston magnet, so it cannot trigger reed or electronic switches. You must select the SDA25X25S variant to enable sensing. Additionally, end stops use a fixed NBR bumper, not an adjustable air cushion.
