The AirTAC AirTAC SDA80X5S Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 5mm 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 SDA80X5S is a double-acting single-rod compact cylinder engineered for high force in tight axial spaces. It delivers a substantial 2513.3 N push and 2267.8 N pull at 0.5 MPa, operating at speeds from 30-500 mm/s. The short riveted body drastically reduces mounting depth compared to round-body alternatives, making it ideal for machinery with limited footprint room.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. End-stops rely on a fixed NBR bumper to decelerate the motion rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorption. The 25 mm piston rod features an M14x1.5 female thread, and air connects via PT3/8 ports.

Provides a rapid 5 mm ejection stroke on small plastic injection molds, utilizing the 2513.3 N force to break parts free from the cavity in confined tooling bases.
Acts as a short-stroke hold-down clamp in progressive stamping presses, securing heavy gauge steel sheet before the cutter descends to prevent material shifting.
Functions as a heavy-duty stopper block in end-of-line palletizer conveyors, instantly halting loaded pallets using its massive 513 kgf maximum push capacity.
When sizing this unit, stepping down to the SDA63 yields 1558.6 N push at 0.5 MPa, while stepping up to the SDA100 provides 3927 N. For this 80 mm bore, the safe working load is approximately 1508 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 128.1 kg with a 2:1 safety margin. Confirm your ordering essentials: 80 mm bore, 5 mm stroke, PT3/8 port, female rod thread, and the -S magnet.
Keep in mind that a standard compact cylinder does not hold its load if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end. If your application must hold a load without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 80 mm bore cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, increasing to 3518.6 N push at 0.7 MPa. The theoretical maximum push force is 513 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa and a proof pressure of 1.5 MPa.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the stroke, not an adjustable air cushion. For high-speed or high-energy cycles, you should add an external shock absorber or slow down the approach speed. The -S option on this unit denotes a built-in magnet for AirTAC reed or electronic switches.
