The AirTAC AirTAC SDA80X25SB Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 25mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA80X25SB is a double-acting single-rod compact cylinder engineered for substantial actuation tasks, delivering a push force of 2513.3 N and a pull force of 2267.8 N at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly shortened unit, drastically reducing axial mounting depth where a conventional round-body actuator would be too bulky. The 80 mm bore features a hard-anodized inner wall and a two-way piston seal for extended operational life.
This specific configuration includes a built-in piston magnet (-S) for direct compatibility with AirTAC reed or electronic switches via the body's peripheral grooves. It is also equipped with a male-thread piston rod end (-B), specifying an M22x1.5 thread for secure mechanical load coupling. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorption to prevent impact damage.

Drives the knockout plate in a plastic injection molding machine, utilizing the 25 mm stroke and 2513.3 N force to eject heavy fabricated parts from the tool cavity.
Actuates a heavy lower die holder in a sheet metal press brake, where the short riveted body minimizes axial footprint and the male M22x1.5 rod secures the heavy tooling.
Operates the heavy diverter gate on an automated palletizing line, relying on the 80 mm bore's 513 kgf maximum thrust to push empty wooden pallets into the staging queue.
Selecting this 80 mm bore involves evaluating your force requirements against neighboring options. If 2513.3 N of push at 0.5 MPa is excessive, stepping down to the SDA63 provides 1558.6 N, conserving space and air consumption. Conversely, if your load demands more power, the SDA100 offers 3927 N of thrust. For this SDA80X25SB configuration, verify that your system operates within the 0.15-1.0 MPa pressure range and that the PT3/8 porting matches your pneumatic manifold.
When integrating this actuator, note that a safe working load is approximately 1508 N (about 60% of the 0.5 MPa push figure), allowing a vertical lift capacity of roughly 128.1 kg with a 2:1 safety margin. Because a standard double-acting cylinder does not hold its position upon air loss or valve centering—the piston will drift and the fixed NBR bumper only decelerates near the stroke end—you must incorporate an external rod lock or a pilot-operated check valve if the application requires suspended load holding.
Quick checklist
At 0.5 MPa, the push force is 2513.3 N and the pull force is 2267.8 N. At 0.7 MPa, the push force is 3518.6 N. The theoretical maximum push force is 513 kgf at the 1.0 MPa maximum operating pressure. The proof pressure is 1.5 MPa.
It uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits; this is not an adjustable air cushion, so high-speed applications may need external shock absorbers. Additionally, it does not intrinsically hold a load if air pressure is lost, requiring an external rod lock or pilot-operated check valve for fail-safe positioning.
