The AirTAC AirTAC SDA25X100H Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 100mm 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 SDA25X100H is a double-acting single-rod compact cylinder engineered with a 25mm bore and 100mm stroke. It generates 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. This specific H-version utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance, operating reliably within the standard -20 to +70 C range. The hard-anodized bore and two-way piston seal ensure durable performance across its 30-500 mm/s speed range.
A short riveted body joins the barrel, rear cover, piston and rod, significantly reducing axial mounting depth compared to round-body units. End-of-travel deceleration is handled by a fixed NBR bumper at each end, which is not an adjustable air cushion. Because this SKU lacks the S option, it has no piston magnet and cannot accept AirTAC reed or electronic switches.

Secures aluminum workpieces onto machining centers. The 245.4 N extend force holds parts firmly for milling, while the FKM seals resist coolant mist exposure.
Drives mechanical arms to tuck corrugated box flaps prior to sealing. The 100mm stroke provides the exact travel needed, and the compact body fits within tight conveyor side frames.
Pushes finished PCBs out of assembly pallets. The 25mm bore offers gentle ejection force, and the hard-anodized inner wall prevents wear from high cycle counts.
When sizing this unit, compare its 245.4 N push at 0.5 MPa against adjacent bores: stepping down to the SDA20 yields 157.1 N, while stepping up to the SDA32 provides 402.1 N. For this 25mm bore, the 10mm piston rod features a female M5x0.8 thread (or male M8x1.25 if ordered with the B option) and connects via an M5x0.8 port. A computed safe working load is roughly 147 N, allowing a vertical lift of approximately 12.5 kg with a 2:1 safety margin.
Note that a plain SDA cylinder does not hold its position if air pressure drops or the valve is centered, as the piston will drift and the fixed bumper only decelerates near stroke end. To suspend a load safely without live pressure, you must integrate an external rod lock or a pilot-operated check valve. If your application requires position sensing, specify the S variant to equip the internal magnet.
Quick checklist
This 25mm bore double-acting cylinder provides 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 force is 50 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa with a proof pressure of 1.5 MPa, and the piston speed ranges from 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot accept AirTAC reed or electronic switches. You would need to order the SDA25X100HS variant to enable sensing. Additionally, end stops rely on a fixed NBR bumper rather than an adjustable air cushion, so external shock absorbers are recommended for high-energy loads.
