The AirTAC AirTAC SDA25X30H Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 30mm 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 SDA25X30H is a double-acting single-rod compact cylinder engineered with a 25 mm bore and 30 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, providing enhanced thermal and oil resistance over the standard NBR configuration. The riveted unibody design merges the barrel and covers, drastically reducing axial mounting depth where a conventional round-body actuator would be too long.
Built for durability, the hard-anodized inner bore houses a two-way piston seal, while end-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. The 10 mm piston rod utilizes a female M5x0.8 thread for load coupling. Because this base model lacks the S option, it has no piston magnet and cannot support position sensing; adding an S suffix would enable the use of reed or electronic switches in the body grooves.

Mounts flush inside tight mold platens to eject plastic parts, leveraging the FKM seal to withstand ambient heat and synthetic lubricants.
Drives short 30 mm folding arms on high-speed packaging lines to tuck corrugated flaps before tape or glue application.
Pushes lightweight parcels at 245.4 N onto secondary conveyor tracks, fitting within the narrow 25 mm frame envelope.
When sizing this actuator, evaluate your force requirements carefully. If you need less thrust, stepping down to the SDA20 provides 157.1 N of push at 0.5 MPa. Conversely, scaling up to the SDA32 yields 402.1 N at the same pressure. For the SDA25X30H, a safe working load is approximately 147 N (about 60% of the 245.4 N figure), translating to a vertical lift capacity of roughly 12.5 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered—the piston will drift. For suspended or vertical loads, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 25 mm bore, 30 mm stroke, M5x0.8 port, female rod thread, and FKM seal.
Quick checklist
At 0.5 MPa, the push force is 245.4 N and the pull force is 206.2 N. At 0.7 MPa, push is 343.6 N and pull is 288.6 N. The theoretical maximum push is 50 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and the operational speed spans 30-500 mm/s.
No. End-of-travel deceleration relies on a fixed NBR bumper, which is not a field-adjustable air cushion; for high kinetic energy, slow the approach or add an external shock absorber. Additionally, this SKU lacks the S magnet option, so it cannot support reed or electronic switches.
