The AirTAC AirTAC SDA80X50H Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 50mm 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 SDA80X50H is a double-acting single-rod compact cylinder engineered for heavy-duty pneumatics within a minimal axial envelope. Utilizing a riveted body assembly, it conserves valuable machine footprint where conventional round-body units fail to fit. At 80 mm bore, it generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa. This SKU features an FKM (fluororubber) seal variant, providing enhanced resistance to higher temperatures and oil exposure.
Equipped with a 25 mm piston rod and PT3/8 air ports, this model handles dynamic loads effectively. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorbers. Because this specific configuration lacks the -S magnet option, it cannot support magnetic position sensing. Theoretical maximum push capacity reaches 513 kgf at 1.0 MPa.

Drives heavy plastic part ejection plates in injection molding machinery, utilizing the 2513.3 N extend force and FKM seals to withstand residual heat and lubricants.
Actuates heavy-gauge metal feeding mechanisms in stamping presses, where the short riveted body conserves floor space and the 25 mm rod resists deflection.
Provides vertical lifting force for automated palletizer hoists, safely managing loads around 128.1 kg when paired with external guidance to prevent side loading.
When sizing this 80 mm bore actuator, consider stepping down to the SDA63, which yields 1558.6 N of push at 0.5 MPa, or moving up to the SDA100 for 3927 N at the same pressure. A safe working load for this cylinder is approximately 1508 N (about 60% of the 0.5 MPa figure), allowing a vertical lift of roughly 128.1 kg with a 2:1 safety margin. To order, confirm the 80 mm bore, 50 mm stroke, PT3/8 port, FKM seals, and the female M14x1.5 rod thread. Note that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. To sustain a suspended load, integrate an external rod lock or a pilot-operated check valve.
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 is 513 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
No, the piston drifts without live air pressure since the fixed NBR bumper only decelerates near stroke end rather than locking the load; use an external rod lock for holding. Additionally, it lacks adjustable air cushions, so high-speed applications require slowing the approach or adding external shock absorbers.
