The AirTAC AirTAC SDA80X75S Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 75mm 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 SDA80X75S is a double-acting, single-rod compact cylinder engineered to deliver substantial thrust within a minimal axial footprint. It generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa, making it suitable for heavy-duty positioning tasks. The riveted body assembly integrates the barrel, rear cover, and piston to significantly reduce overall length compared to traditional round-body units.
This specific configuration includes a built-in piston magnet (the -S option) for use with AirTAC reed or electronic switches mounted in the body grooves. It features a 25 mm piston rod, a PT3/8 air port, and relies on a fixed NBR bumper at each end to decelerate the stroke end. Note that this fixed bumper is not an adjustable air cushion; for high-energy cycles, an external shock absorber is advised.

Uses the 2513.3 N extend force to knock heavy stamped metal panels out of a die, where the short riveted body fits neatly within the press frame.
Pushes loaded pallets sideways at 30-500 mm/s onto a secondary packaging line, benefiting from the 25 mm rod rigidity against lateral deflection.
Actuates heavy lifting gates on woodworking machinery, requiring the -S magnet to trigger reed or electronic switches for upper and lower position confirmation.
Selecting this 80 mm bore model provides 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 approximately 128.1 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA63 yields 1558.6 N at 0.5 MPa, while scaling up to the SDA100 provides 3927 N for heavier demands. Be aware that a plain SDA cylinder does not hold its load if air pressure is lost or the valve is centered—the piston will drift, as the fixed bumper only decelerates near the stroke end. For suspended or vertical loads, an external rod lock or pilot-operated check valve is required. When ordering, confirm the 80 mm bore, 75 mm stroke, PT3/8 port, built-in magnet (S), and the female M14x1.5 rod-end thread.
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 operating pressure limit.
No, the cylinder uses a fixed NBR bumper at each end to decelerate the stroke end, which is not an adjustable air cushion. Additionally, it does not function as a brake; the piston will drift if air is lost. For position holding, you must use an external rod lock.
