The AirTAC AirTAC SDA80X120H Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 120mm 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 SDA80X120H is a double-acting single-rod compact cylinder engineered for heavy-duty pneumatics within a minimal axial footprint. Utilizing a short riveted body assembly, it conserves valuable machine mounting depth where standard round-body or profile units cannot fit. This 80 mm bore model generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa, featuring a 25 mm piston rod and PT3/8 air ports. The H designation indicates fluororubber (FKM) seals for enhanced thermal and oil resistance.
End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber. Because this specific SKU lacks the S option, it has no piston magnet and cannot support position sensing. Operating speeds span 30-500 mm/s across a 0.15-1.0 MPa pressure range.

Drives heavy plastic part ejection plates in injection molding machinery, utilizing the 2513.3 N extend force and FKM seals to withstand ambient heat near mold tooling.
Deploys robust folding arms on automated palletizing lines to tuck cardboard flaps, benefiting from the compact riveted body to fit within tight conveyor framing.
Actuates heavy-duty material guides and clamps in sheet metal stamping presses, where the 120 mm stroke positions blanks accurately under high impact loads.
When sizing this actuator, evaluate your force margins carefully. Stepping down to the SDA63 yields 1558.6 N of push at 0.5 MPa, while stepping up to the SDA100 provides 3927 N. At 0.5 MPa, the SDA80X120H offers a safe working load of roughly 1508 N (about 60% of its output) and a vertical lift capacity of 128.1 kg with a 2:1 safety margin. To confirm your order, verify the 80 mm bore, 120 mm stroke, PT3/8 porting, female M14x1.5 rod thread, and FKM seal specification. Note that a standard cylinder drifts when air is lost; maintaining a load without live pressure demands an external rod lock or 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, 3518.6 N push and 3175 N pull at 0.7 MPa, with a theoretical maximum push of 513 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, proof pressure is 1.5 MPa, and speed ranges from 30-500 mm/s.
This SKU lacks the S option, so it has no internal piston magnet and cannot accept reed or electronic switches. Additionally, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion; high-speed applications should incorporate external shock absorbers.
