The AirTAC AirTAC SDA25X25SH Compact Cylinder | 25mm Bore 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.
The AirTAC SDA25X25SH is a double-acting, single-rod compact cylinder engineered with a 25 mm bore and 25 mm stroke. It generates 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. The riveted unibody design pairs the barrel, rear cover, piston, and rod into a highly integrated assembly, drastically reducing axial mounting depth compared to conventional round-body units. This specific configuration includes an -S piston magnet for position sensing and an -H fluororubber (FKM) seal upgrade for enhanced thermal and oil resistance.
End-of-travel deceleration is handled by a fixed NBR bumper at each end rather than an adjustable air cushion, meaning operators cannot tune the end-stop impact externally. The hard-anodized 25 mm bore houses a 10 mm piston rod, and the body features integrated magnetic-switch grooves compatible with AirTAC reed or electronic solid-state sensors. Operating speed spans 30-500 mm/s across a 0.15-1.0 MPa pressure range.

Secures aluminum workpieces inside machining centers. The FKM seals resist cutting fluid mist, while the 245.4 N push force locks parts firmly against locating pins without shifting during high-speed milling.
Deploys a 25 mm stroke to tuck inner flaps on corrugated boxes before tape sealing. The compact riveted body fits tightly within narrow side frames, maximizing usable conveyor width.
Moves a metering nozzle precisely over microplate wells. The built-in magnet interfaces with electronic solid-state switches to confirm nozzle retraction before the indexing table advances.
When sizing this 25 mm bore actuator, evaluate your force margins carefully. Stepping down to the SDA20 yields 157.1 N of push at 0.5 MPa, while stepping up to the SDA32 provides 402.1 N. The SDA25X25SH provides a safe working load of roughly 147 N—about 60% of its 245.4 N output at 0.5 MPa—translating to a vertical lift capacity of approximately 12.5 kg with a 2:1 safety factor. If your mechanism must maintain vertical position during air loss or valve centering, note that this cylinder will drift; a pilot-operated check valve or external rod lock is required for true load holding. Confirm your ordering essentials: 25 mm bore, 25 mm stroke, M5x0.8 port, female M5x0.8 rod thread, -S magnet, and -H FKM seals.
Quick checklist
At 0.5 MPa, this 25 mm bore cylinder outputs 245.4 N of push force and 206.2 N of pull force. At 0.7 MPa, push increases to 343.6 N and pull to 288.6 N. The theoretical maximum push capacity is 50 kgf at the 1.0 MPa operating pressure limit.
No, the SDA25X25SH relies on fixed NBR bumpers to decelerate the piston at stroke ends, not an adjustable air cushion. For high kinetic energy or rapid cycling, you should slow the approach speed or install an external shock absorber to prevent internal damage.
