The AirTAC AirTAC SDA80X15BH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 15mm 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 SDA80X15BH is a double-acting, single-rod compact cylinder engineered for high-force actuation within a minimal axial footprint. Utilizing a riveted body assembly, it conserves valuable mounting depth where conventional round-body units cannot fit. At 0.5 MPa, it generates 2513.3 N of push force and 2267.8 N of pull force, operating via a PT3/8 port and a robust Ø25 mm piston rod.
This specific configuration includes a male M22x1.5 threaded rod end for secure mechanical load coupling, and an -H fluororubber (FKM) seal variant for enhanced thermal and oil resistance. The unit relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot support magnetic position sensing.

Drives heavy mold separation pins in plastic injection machinery, utilizing the 2513.3 N extend force and FKM seals to withstand elevated ambient temperatures.
Applies brief 15 mm high-impact strokes to tension and seal steel strapping around heavy export pallets, fitting into the narrow gantry clearance.
Ejects thick-gauge stamped metal plates from progressive dies, leveraging the rigid Ø25 mm male-threaded rod to push parts clear of the tooling.
When sizing this 80 mm bore model, consider stepping down to the SDA63, which yields 1558.6 N of push at 0.5 MPa, or scaling up to the SDA100, which provides 3927 N at the same pressure. For this 15 mm stroke, the theoretical safe working load is approximately 1508 N (about 60% of the 0.5 MPa push force), allowing a vertical lift of roughly 128.1 kg with a 2:1 safety margin. Note that a standard compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates near the stroke end and does not function as a locking brake. To maintain position, integrate an external rod lock or a pilot-operated check valve. Ensure your ordering essentials capture the 80 mm bore, 15 mm stroke, PT3/8 port, male M22x1.5 rod thread, and FKM seals.
Quick checklist
This 80 mm bore double-acting cylinder provides 2513.3 N push and 2267.8 N pull at 0.5 MPa, and 3518.6 N push at 0.7 MPa. The theoretical maximum push force is 513 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa and a speed range of 30-500 mm/s.
No, this specific SKU does not include the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to select the -S variant to enable position sensing. Additionally, end-stop deceleration is handled by a fixed NBR bumper, not an adjustable air cushion.
