The AirTAC AirTAC SDA80X20SH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 20mm 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 SDA80X20SH is a double-acting single-rod compact cylinder engineered for high-force tasks in tight axial footprints. It generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa, utilizing a robust 25 mm piston rod. The short riveted body drastically reduces overall mounting length compared to standard round-body units, making it ideal for machinery where depth is restricted.
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-stopping relies on a fixed NBR bumper that decelerates the piston near stroke limits rather than an adjustable air cushion. Operating pressure spans 0.15-1.0 MPa, with a speed range of 30-500 mm/s.

Drives short-stroke ejection pins inside densely packed injection molding machines, leveraging the compact riveted body to fit within narrow mold platens.
Applies 2513.3 N of clamping force at 0.5 MPa to hold heavy gauge sheet metal firmly in place during progressive stamping operations.
Positions heavy chassis components on robotic welding lines, utilizing the FKM seals to withstand elevated ambient heat and weld spatter contamination.
Selecting this 80 mm bore provides substantial power, yielding a safe working load of roughly 1508 N (about 60% of the 2513.3 N push at 0.5 MPa) and a vertical lift capacity of 128.1 kg with a 2:1 margin. If your application requires less force, stepping down to the SDA63 yields 1558.6 N at 0.5 MPa; conversely, scaling up to the SDA100 provides 3927 N. Be aware that a standard actuator drifts when air is lost or the valve is centered, as the fixed bumper only decelerates near the stroke end and acts as neither a lock nor a brake—install an external rod lock or pilot-operated check valve if you must hold a load safely.
When ordering, confirm the 80 mm bore, 20 mm stroke, PT3/8 port, built-in magnet (S), female M14x1.5 rod-end thread, and FKM seals (H).
Quick checklist
This double-acting cylinder delivers 2513.3 N push and 2267.8 N pull at 0.5 MPa, 3518.6 N push at 0.7 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion; for high-energy cycles, add an external shock absorber. Furthermore, it will not hold a load if air pressure drops—the piston drifts, so an external rod lock or pilot-operated check valve is required for secure holding.
