The AirTAC AirTAC SDA80X140 Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 140mm 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 SDA80X140 is a double-acting, single-rod compact cylinder engineered to deliver a robust 2513.3 N push force at 0.5 MPa. Utilizing a short riveted body design, it significantly reduces axial mounting depth compared to conventional round-body units, saving valuable machine footprint in tight assemblies. The hard-anodized bore and two-way piston seal ensure durable, long-lasting operation.
This specific 140 mm stroke configuration exceeds the 130 mm maximum standard stroke for the 80 mm bore, making it a non-standard, made-to-order unit. 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 end stop. Note that this SKU lacks a piston magnet and cannot support magnetic sensing; adding the -S option enables reed or electronic switches.

Drives heavy press dies for automotive body panel forming, utilizing the 2513.3 N push force to shape high-strength steel within a minimal axial frame envelope.
Actuates heavy-duty diverting arms on automated warehouse conveyors, moving loaded pallets laterally with a safe working load of 1508 N.
Raises and lowers heavy clamping platens in multi-layer wood gluing presses, where the 140 mm stroke accommodates thick material batches.
When sizing this actuator, consider stepping down to the SDA63, which provides 1558.6 N of push force at 0.5 MPa, or stepping up to the SDA100, which yields 3927 N at 0.5 MPa. For the SDA80X140, 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. Keep in mind that a plain compact cylinder does not hold its load if air pressure is lost or the valve is centered—the piston will drift, and the fixed bumper only decelerates near the stroke end. For applications requiring position holding, an external rod lock or pilot-operated check valve is required. Confirm your ordering essentials: 80 mm bore, 140 mm non-standard stroke, PT3/8 port, female M14x1.5 rod thread, and no magnet.
Quick checklist
The SDA80X140 generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 3518.6 N. The theoretical maximum push force is 513 kgf at 1.0 MPa, which is the maximum operating pressure.
No, this actuator uses a fixed NBR bumper to decelerate the stroke end, which is not an adjustable air cushion. Additionally, it does not hold its load on air loss or when a valve is centered; the piston will drift. For vertical load holding, you must use an external rod lock or pilot-operated check valve.
