The AirTAC AirTAC SDA25X10SB Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 10mm 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 SDA25X10SB is a double-acting single-rod compact cylinder engineered for tight axial spaces. It delivers a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa. The riveted body design drastically reduces overall length compared to round-body alternatives, making it ideal for machinery with shallow mounting depth. A 10 mm stroke provides precise short-travel motion.
This configuration includes a built-in piston magnet (-S) for position detection using AirTAC reed or electronic switches mounted in the body grooves. It also features a male-thread piston rod (-B) with an M8x1.25 thread for secure load coupling. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, ensuring consistent deceleration across the 30-500 mm/s speed range.

Provides precise 10 mm lateral correction on a printed circuit board conveyor using the 245.4 N push force and integrated position sensing.
Executes rapid, short-stroke flap tucking on a packaging line where the compact riveted body minimizes machine footprint.
Drives an M8x1.25 male-threaded locating pin into a sheet metal stamping fixture, ensuring positive alignment before welding.
Selecting this 25 mm bore model provides a safe working load of roughly 147 N (about 60% of the 245.4 N push at 0.5 MPa), translating to a vertical lift capacity of approximately 12.5 kg with a 2:1 safety margin. If your application requires less force, the SDA20 bore offers 157.1 N at 0.5 MPa; for heavier demands, the SDA32 bore steps up to 402.1 N. Keep in mind that a plain SDA cylinder does not hold its position if air pressure drops or the valve is centered—the piston will drift, and the fixed bumper only decelerates near the stroke end. For load holding, an external rod lock or pilot-operated check valve is required. When ordering, confirm the 25 mm bore, 10 mm stroke, M5x0.8 port, -S magnet, and -B male M8x1.25 rod thread.
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, the push force is 343.6 N and the pull force is 288.6 N. The theoretical maximum push force is 50 kgf at the maximum operating pressure of 1.0 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. Additionally, it does not function as a lock or brake; if air is lost, the piston drifts. For load holding, you must use an external rod lock or pilot-operated check valve.
