The AirTAC AirTAC SDA25X25SB Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 25mm 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 SDA25X25SB is a double-acting, single-rod compact cylinder engineered for tight axial spaces. A riveted assembly unites the barrel, rear cover, and piston, yielding a minimal footprint while delivering 245.4 N of push force at 0.5 MPa. The 25 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable pneumatic operation.
This specific configuration includes an integrated piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. The -B option specifies a male M8x1.25 threaded piston rod end, providing a robust mechanical coupling for your load. End-of-stroke deceleration relies on fixed NBR bumpers rather than adjustable air cushions, keeping the overall length exceptionally short.

Actuates the Z-axis plunge on a compact PCB depaneling router, utilizing the 25 mm stroke and male M8 rod end to maintain precise depth control within a narrow gantry frame.
Folds minor corrugated box flaps on a continuous packaging line, where the 245.4 N push force easily overcomes board resistance and the short riveted body conserves conveyor spacing.
Drives a precision metering valve for reagent dispensing, using the integrated magnet to trigger an electronic switch for exact shot volume confirmation.
When sizing this unit, compare its 245.4 N push at 0.5 MPa against adjacent bores: stepping down to the SDA20 yields 157.1 N, while moving up to the SDA32 provides 402.1 N. For this 25 mm bore, a safe working load is approximately 147 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 12.5 kg with a 2:1 safety margin. To finalize your order, confirm the 25 mm bore, 25 mm stroke, M5x0.8 port, the required -S magnet, and the -B male M8x1.25 rod thread. Note that a standard SDA does not hold its position upon air loss; the piston will drift, so applications requiring load holding need an external rod lock or pilot-operated check valve.
Quick checklist
This double-acting cylinder generates a push force of 245.4 N and a pull force of 206.2 N 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 on filtered air between 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
It uses fixed NBR bumpers at both ends to decelerate the piston near stroke completion; these are not adjustable air cushions, so external shock absorbers are advised for high-speed approaches. The -B option equips the 10 mm rod with a male M8x1.25 thread, replacing the standard female M5x0.8 end.
