The AirTAC AirTAC SDA25X60SB Compact Cylinder | 25mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 60mm 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 SDA25X60SB 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. Its riveted assembly merges the barrel, rear cover, piston, and rod to drastically reduce axial mounting depth, making it ideal for machinery where a standard round-body unit would protrude too far. The hard-anodized bore ensures smooth low-friction travel across the 60 mm stroke.
This specific configuration includes a built-in piston magnet (S) for position detection and a male-thread piston rod end (B). The magnet allows you to drop AirTAC reed or electronic switches directly into the body grooves. The M8x1.25 male rod end provides a robust mechanical coupling for your load, though you should avoid side-loading the 10 mm rod to prevent premature seal wear.

Actuates a routing flap on a packaging conveyor, utilizing the 60 mm stroke to push parcels cleanly from the main belt onto a secondary sorting lane.
Secures circuit boards during automated soldering or inspection, using the 245.4 N extend force to hold the panel firmly against a fixed guide rail.
Functions as a pop-up stopper in gravity flow rack systems, extending to halt plastic totes and retracting to release them down the picking lane.
Selecting this 25 mm bore unit gives you a safe working load of roughly 147 N (about 60 percent of the 245.4 N push at 0.5 MPa) and a vertical lift capacity near 12.5 kg with a 2:1 safety margin. If your application requires less force, you can step down to the SDA20, which provides 157.1 N of push at 0.5 MPa. Conversely, if you need more thrust, the SDA32 steps up to 402.1 N at the same pressure. Keep in mind that a plain compact cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed NBR bumper only decelerates it near the stroke end. For vertical or suspended loads, add an external rod lock or a pilot-operated check valve. When ordering, confirm the 25 mm bore, 60 mm stroke, M5x0.8 port, magnet (S), and male M8x1.25 rod thread.
Quick checklist
This double-acting 25 mm bore cylinder generates 245.4 N push and 206.2 N pull at 0.5 MPa, and 343.6 N push at 0.7 MPa. Its theoretical maximum thrust is 50 kgf at the 1.0 MPa operating pressure limit.
No, the SDA series uses a fixed NBR bumper at each end to absorb end-stop impact rather than a field-adjustable air cushion. For high-speed or high-energy cycles, you should slow the approach speed or install an external shock absorber.
