The AirTAC AirTAC SDA80X40H Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 40mm 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 SDA80X40H is a double-acting single-rod compact cylinder featuring an 80 mm bore and 40 mm stroke. It generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa. The -H designation indicates fluororubber (FKM) seals for improved oil and thermal resistance within the -20 to +70 C operating range. Its short riveted body integrates the barrel, rear cover, piston, and rod, significantly reducing axial mounting depth compared to standard round-body units.
This model uses a 25 mm piston rod and PT3/8 air ports. End-stop deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-energy cycles. Because this specific SKU lacks the -S magnet option, it cannot support magnetic position sensing.

Provides the 2513.3 N push force required to eject heavy plastic parts from mold platens, with FKM seals resisting thermal degradation from ambient heat.
Handles the robust 128.1 kg vertical lift requirement to eject stamped metal panels from hydraulic presses while minimizing axial machine footprint.
Raises loaded pallets in packaging lines where the compact riveted body saves valuable vertical space without sacrificing the 513 kgf maximum thrust.
When sizing this actuator, stepping down to the SDA63 yields 1558.6 N of push at 0.5 MPa, while stepping up to the SDA100 provides 3927 N. The 80 mm bore offers a safe working load of roughly 1508 N (about 60% of its 0.5 MPa capacity) and can vertically lift approximately 128.1 kg with a 2:1 safety margin. To order, confirm the 80 mm bore, 40 mm stroke, PT3/8 port thread, FKM seals, and the standard female M14x1.5 rod end. Note that this cylinder drifts if air pressure is lost; use an external rod lock or pilot-operated check valve for strict 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, push is 3518.6 N. The theoretical maximum push is 513 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, speed is 30-500 mm/s, and the standard stroke limit for this bore is 130 mm.
No, this specific SKU does not include the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify the -S option for sensing. Additionally, end-stop deceleration uses a fixed NBR bumper, not an adjustable cushion.
