The AirTAC AirTAC SDA25X5H Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 5mm 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 SDA25X5H is a double-acting single-rod compact cylinder engineered for extremely short axial movements. It provides a 245.4 N push force at 0.5 MPa alongside a 206.2 N pull force, making it suitable for high-cycle positioning tasks. This specific SKU features an FKM fluororubber seal for enhanced thermal and oil resistance, operating within the standard -20 to +70 C range.
Its riveted body construction integrates the barrel, rear cover, piston, and rod to minimize overall length, saving valuable mounting space where a round-body unit would not fit. The unit incorporates a fixed NBR bumper at each end to decelerate the stroke end rather than an adjustable air cushion. Because this configuration lacks the -S magnet code, it cannot host AirTAC reed or electronic switches.

Uses the 5 mm stroke and 245.4 N push to eject delicate printed circuit boards from a testing fixture without stressing the surrounding components.
Employs the short 25 mm bore body to tuck packaging film edges in tight wrapping machinery where axial depth is highly restricted.
Leverages the FKM seal and 206.2 N pull force to actuate a chemical dispenser valve safely in environments with light oil exposure.
When sizing this unit, evaluate your force requirements bidirectionally: 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. For the SDA25X5H, the safe working load is approximately 147 N (about 60% of the 245.4 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 12.5 kg with a 2:1 safety margin. Confirm your ordering essentials: 25 mm bore, 5 mm stroke, M5x0.8 port, female M5x0.8 rod thread, and FKM seals.
Remember that a standard compact cylinder does not hold its load if air pressure drops or the valve is centered. The piston will drift, and the fixed bumper only decelerates the stroke near its limits without acting as a mechanical lock. If your application demands position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting 25 mm bore cylinder delivers a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa. 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. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed of 30-500 mm/s.
No, this specific SKU does not include the -S piston magnet, so it cannot host AirTAC reed or electronic switches. You would need to specify the -S option to enable sensor grooves. Additionally, it uses fixed NBR bumpers for end-stop deceleration rather than adjustable air cushions.
