The AirTAC AirTAC SDA80X150 Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 150mm 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 SDA80X150 is a double-acting single-rod compact cylinder engineered to deliver 2513.3 N of push force at 0.5 MPa. This specific configuration features an 80 mm bore and a 150 mm stroke, which exceeds the 130 mm standard maximum for this bore size, making it a non-standard, made-to-order unit. Its short riveted body design significantly reduces axial mounting depth, saving valuable machine footprint where a conventional round-body cylinder would be too bulky.
This model incorporates a fixed NBR bumper at each end to decelerate the piston near stroke limits, but it is not an adjustable air cushion. Operating at speeds of 30-500 mm/s, it utilizes a 25 mm piston rod and PT3/8 air ports. Because this SKU lacks the -S option, it has no piston magnet and cannot support magnetic switches; the -S variant would be required for reed or electronic switch sensing.

Drives heavy mold ejector pins in plastic injection machinery, utilizing the 2513.3 N push force to reliably strip large automotive interior panels from the tool cavity.
Raises and lowers heavy product layers within end-of-line packaging lines, where the short riveted body minimizes axial height constraints in tight transfer zones.
Pushes heavy gauge steel blanks into a hydraulic press brake, requiring the robust 25 mm piston rod to withstand high inertial loads during rapid 30-500 mm/s advancement.
When sizing this actuator, consider stepping down to the SDA63, which provides 1558.6 N of push at 0.5 MPa, or stepping up to the SDA100, which yields 3927 N at the same pressure. A safe working load for this 80 mm bore is approximately 1508 N (about 60% of the 2513.3 N figure), allowing a vertical lift of roughly 128.1 kg with a 2:1 safety margin. Keep in mind that a plain SDA body does not hold its load if air pressure is lost or the valve is centered, as the piston will drift and the fixed bumper only decelerates near the stroke end; an external rod lock or pilot-operated check valve is required for secure load holding. To order, confirm the 80 mm bore, 150 mm non-standard stroke, PT3/8 port, female rod-end thread (M14x1.5), and the absence of a magnet.
Quick checklist
This double-acting single-rod cylinder generates 2513.3 N of push and 2267.8 N of pull at 0.5 MPa. At 0.7 MPa, the push increases to 3518.6 N. The theoretical maximum push is 513 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this SKU uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. Additionally, it lacks the -S magnet option, meaning it cannot support reed or electronic switches; high-speed applications may require an external shock absorber.
