The AirTAC AirTAC SDA25X15S Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 15mm 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 SDA25X15S is a double-acting, single-rod compact cylinder engineered to deliver 245.4 N of push force and 206.2 N of pull force at 0.5 MPa. Driven by an M5x0.8 air port, it operates efficiently across a 30-500 mm/s speed range. Because the short riveted body integrates the barrel, rear cover, piston and rod into one highly unified assembly, it drastically reduces axial mounting depth compared to conventional round-body units. This space-saving footprint is ideal for machinery where every millimeter of depth counts.
Equipped with a built-in piston magnet (the -S option), this unit is fully compatible with AirTAC magnetic reed or electronic switches mounted directly into the body grooves. The 10 mm piston rod features a standard female M5x0.8 thread for straightforward load coupling. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, ensuring reliable stopping without adding bulk to the assembly.

Applies 245.4 N of lateral push at 0.5 MPa to align printed circuit boards within pick-and-place machines, utilizing the 15 mm stroke to nudge panels into exact position before component placement.
Deploys the 10 mm rod to tuck minor flaps on small packaging lines, where the short riveted body minimizes axial intrusion into congested conveyor framing.
Pushes molded plastic connectors out of test fixtures using a reliable 206.2 N retract pull at 0.5 MPa, triggering an AirTAC electronic switch via the internal magnet to confirm ejection.
When sizing this 25 mm bore model, consider stepping down to the SDA20 if your application requires less force, as it provides 157.1 N of push at 0.5 MPa. Conversely, if your load demands more power, the SDA32 offers a substantial increase to 402.1 N at the same pressure. For the SDA25X15S specifically, 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. To finalize your order, confirm the 15 mm stroke, M5x0.8 port, the required female M5x0.8 rod thread, and the built-in magnet option. Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the piston near the stroke end and does not function as a locking brake. If your process must hold a load without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder generates 245.4 N push and 206.2 N pull at 0.5 MPa, increasing to 343.6 N push and 288.6 N pull at 0.7 MPa. The theoretical maximum push force is 50 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, handles temperatures from -20 to +70 C, and has a speed range of 30-500 mm/s.
No, the SDA25X15S relies on a fixed NBR bumper at each end to absorb end-of-stroke impact. It is not an adjustable air cushion and does not act as a brake. For high-speed or high-energy cycles, you should slow the approach speed or install an external shock absorber to prevent damage.
