The AirTAC AirTAC SDA25X5SB 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 SDA25X5SB is a double-acting single-rod compact cylinder engineered for tight axial spaces. It generates 245.4 N of push force and 206.2 N of pull force at 0.5 MPa, utilizing a hard-anodized bore and a two-way piston seal for reliable operation.
This specific configuration includes a built-in piston magnet (-S) for use with AirTAC reed or electronic switches, and a male M8x1.25 threaded rod end (-B) instead of the default female thread. The riveted body design drastically reduces mounting depth, while fixed NBR bumpers absorb end-stop impact across its 5 mm stroke.

Secures circuit boards during automated soldering or inspection with a precise 5 mm travel, utilizing the 245.4 N push force without stressing the delicate panel.
Actuates a short nipper arm on a vertical form-fill-seal machine to grab and cut packaging film, taking advantage of the male M8x1.25 rod end for secure tool mounting.
Pushes small electronic sensor blocks out of a machining fixture, where the compact riveted body minimizes footprint and the integrated magnet tracks position via a reed or electronic switch.
When sizing this actuator, consider stepping down to the SDA20 which provides 157.1 N of push at 0.5 MPa, or moving up to the SDA32 which yields 402.1 N at the same pressure. For the SDA25X5SB, the safe working load is approximately 147 N (about 60% of its 245.4 N capacity), allowing a vertical lift of roughly 12.5 kg with a 2:1 safety margin. Confirm your ordering essentials: 25 mm bore, 5 mm stroke, M5x0.8 port, male M8x1.25 rod thread, and an integrated sensor magnet.
Keep in mind that a standard compact cylinder will not hold a load if air pressure drops or the valve is centered; the piston will drift. The fixed NBR bumper only decelerates the stroke near the end and does not act as a locking brake. If your application requires strict position holding, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 25 mm bore double-acting cylinder provides 245.4 N push and 206.2 N pull at 0.5 MPa, and 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 between 0.15 and 1.0 MPa, with a speed range of 30-500 mm/s.
No, the SDA25X5SB uses fixed NBR bumpers at each end to decelerate the piston, which are not field-adjustable. If operating at high speeds or with heavy energy loads, you should add an external shock absorber or slow down the approach. It is not equipped with an adjustable air cushion.
