The AirTAC AirTAC SDA25X15H Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 15mm 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 SDA25X15H is a double-acting single-rod compact cylinder engineered with a 25 mm bore and 15 mm stroke. It generates 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. This specific SKU features an H-designation fluororubber (FKM) seal, elevating oil and heat endurance beyond the standard NBR equipment. The riveted body assembly minimizes axial footprint, fitting easily into tight machine layouts.
It carries a 10 mm piston rod and uses an M5x0.8 air port. End-stop deceleration relies on fixed NBR bumpers rather than adjustable pneumatic cushions, meaning operators should reduce approach velocity or install external shock absorbers for high-energy cycles. Because this base configuration lacks the S option, it has no piston magnet and cannot host reed or electronic switches.

Actuates the cutting tool feed on an electronics depaneling machine, where the 15 mm stroke and compact riveted body conserve floor space while the FKM seals withstand ambient heat.
Provides 245.4 N of clamping thrust at 0.5 MPa to close blister packaging dies, utilizing the short stroke to maintain high cycle rates without excessive overtravel.
Pushes PET bottles into secondary packaging lanes on a high-speed filling line, relying on the 10 mm rod to endure repetitive lateral diversion tasks.
When sizing this unit, evaluate your neighbors: stepping down to the SDA20 reduces output to 157.1 N push at 0.5 MPa, while upgrading to the SDA32 increases it to 402.1 N. For this 25 mm bore, a safe working load is roughly 147 N (about 60% of the 245.4 N figure), translating to a 12.5 kg vertical lift with a 2:1 safety margin. Confirm your ordering essentials: 25 mm bore, 15 mm stroke, M5x0.8 port, FKM seals, female rod thread, and no magnet.
Remember that a standard compact actuator will drift and drop its load if air pressure drops or the directional valve centers. The fixed bumper only slows travel near the stroke extremes and acts purely as an end-stop, never as a braking device. To suspend loads safely without live pressure, integrate an external rod lock or pilot-operated check valve into your circuit.
Quick checklist
This 25 mm bore cylinder outputs 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 is 50 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, proof pressure is 1.5 MPa, and speed ranges from 30-500 mm/s.
No, this specific SKU lacks the S option, meaning it has no piston magnet and cannot trigger reed or electronic switches. You would need the SDA25X15HS variant for sensing capabilities. Additionally, it uses fixed NBR bumpers for end-stop deceleration, not an adjustable air cushion.
