The AirTAC AirTAC SDA25X10S 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 SDA25X10S is a double-acting, single-rod compact cylinder engineered for tight machinery layouts. It generates 245.4 N of push force and 206.2 N of pull force at 0.5 MPa, operating via an M5x0.8 port. The riveted unibody design significantly reduces axial mounting depth compared to conventional round-body units, making it ideal for space-constrained footprints.
Equipped with a built-in piston magnet (-S), this unit supports position detection using an AirTAC reed or electronic switch fitted into the body grooves. The bore is hard-anodized for longevity, while a fixed NBR bumper at each end absorbs end-stop impact. With a 10 mm stroke and 10 mm rod diameter, it is built for rapid, short-travel actuation at speeds between 30 and 500 mm/s.

Uses the 245.4 N extend force to nudge printed circuit boards into exact alignment on an SMT pick-and-place conveyor before component mounting.
Employs the 10 mm stroke to swiftly tuck minor carton flaps prior to tape sealing, fitting easily within narrow packaging machine frames.
Acts as a short-travel locator pin in stamping presses, registering light gauge sheet metal against a hard stop without occupying valuable bed depth.
This 25 mm bore provides a safe working load of roughly 147 N (about 60% of its 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 offers 157.1 N at 0.5 MPa; for heavier demands, the SDA32 steps up to 402.1 N at 0.5 MPa. When ordering, confirm the 10 mm stroke, M5x0.8 port, female M5x0.8 rod-end thread, and the required magnetic switch.
Because the fixed NBR bumper only decelerates the piston near the stroke end, this cylinder will not hold a load if air pressure drops or the valve is centered—the piston will drift. For applications requiring position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder delivers 245.4 N push and 206.2 N pull at 0.5 MPa, 343.6 N push and 288.6 N pull at 0.7 MPa, with a theoretical maximum push of 50 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, withstands 1.5 MPa proof pressure, and runs at speeds of 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion and not a locking brake. The -S option denotes a built-in magnet for track-mounted AirTAC reed or electronic switches, enabling precise end-position detection.
