The AirTAC AirTAC SDA80X35S Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 35mm 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 SDA80X35S is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted assembly of the barrel, rear cover, and piston yields a very short overall length, saving valuable machine mounting depth where a conventional round-body unit would not fit. Delivering 2513.3 N of push force at 0.5 MPa, this 80 mm bore unit is built for substantial load movement.
This specific model includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to prevent impact damage. The 25 mm piston rod and PT3/8 air port ensure robust pneumatic supply and load coupling for industrial demands.

Drives heavy stamping dies and holding fixtures on automotive assembly lines, utilizing the 2513.3 N push force to form and secure steel body panels.
Actuates heavy-load diverting arms on packaging conveyors, where the short riveted body minimizes protrusion into tight transfer zones while moving loaded pallets.
Ejects heavy forged parts from CNC lathe chucks, relying on the 25 mm piston rod to push metal components clear of the cutting area during automated unloading.
Selecting this 80 mm bore provides a significant step up from the SDA63, which offers 1558.6 N of push at 0.5 MPa. If your application requires even more power, the SDA100 delivers 3927 N at the same pressure. For the SDA80X35S, a safe working load is approximately 1508 N (about 60% of the 2513.3 N figure), translating to a vertical lift capacity of roughly 128.1 kg with a 2:1 safety margin. Ensure you specify the 35 mm stroke, PT3/8 port, female M14x1.5 rod thread, and the required magnetic switch option when ordering.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure is lost or the directional valve is centered; the piston will drift, and the fixed bumper only decelerates the stroke near its end without acting as a mechanical brake. If your machine requires absolute position holding, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This 80 mm bore double-acting cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa. At 0.7 MPa, the push increases to 3518.6 N. The theoretical maximum push force is 513 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a speed range of 30-500 mm/s.
No, the SDA80X35S uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits; it is 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 to prevent end-cap damage.
