The AirTAC AirTAC SDA25X15SH 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 SDA25X15SH is a double-acting, single-rod compact cylinder engineered where axial space is strictly limited. Its riveted body assembly minimizes mounting depth compared to conventional round-body units, yielding a 245.4 N push force at 0.5 MPa. Equipped with an M5x0.8 port and a 10 mm piston rod, it provides a safe working load of roughly 147 N (about 60 percent of its 0.5 MPa capacity) and can vertically lift approximately 12.5 kg with a 2:1 safety margin.
This specific configuration includes an -S piston magnet for direct mounting of AirTAC reed or electronic switches along the body grooves, plus an -H fluororubber (FKM) seal variant for enhanced thermal and oil resistance. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach speed or add external shock absorbers for high-energy loads.

Positions and clamps delicate printed circuit boards during routing or inspection, utilizing the 15 mm stroke and FKM seals to resist flux vapors.
Actuates the sealing jaw on a vertical form-fill-seal machine, where the short riveted body saves depth and the fixed bumper arrests the rapid 15 mm cut stroke.
Drives a short 15 mm linear shift for a multi-head liquid dispenser, relying on the -S magnet to trigger solid-state sensors for precise volume metering.
When sizing this unit, verify if the 245.4 N output at 0.5 MPa fits your requirement or if stepping to a neighbor is better. Stepping down to the SDA20 provides 157.1 N, while stepping up to the SDA32 yields 402.1 N. To confirm your ordering essentials for this model: specify the 25 mm bore, 15 mm stroke, M5x0.8 port, built-in magnet (S), and female M5x0.8 rod-end thread. Note that a plain SDA cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift. If your application must maintain a load without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 25 mm bore double-acting cylinder generates a 245.4 N push and 206.2 N pull at 0.5 MPa. At 0.7 MPa, the push increases to 343.6 N. The theoretical maximum push is 50 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds from 30 to 500 mm/s.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. For high-speed cycles, slow the approach or add an external shock absorber. Additionally, it lacks a locking mechanism; if air is lost, the piston drifts, so an external rod lock or pilot-operated check valve is required to hold a load.
