The AirTAC AirTAC SDA80X30H Compact Cylinder | 80mm Bore FKM is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 30mm 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 SDA80X30H is a double-acting single-rod compact cylinder engineered with a short riveted body to minimize axial mounting depth in tight machinery footprints. It generates a substantial 2513.3 N push force and 2267.8 N pull force at 0.5 MPa, utilizing a hard-anodized 80 mm bore and a two-way piston seal for reliable pneumatic operation.
This specific SKU includes an H-designation fluororubber (FKM) seal for enhanced thermal and oil resistance. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or add external shock absorbers for high-energy loads. The 25 mm piston rod features an M14x1.5 female thread, and because this unit lacks the S option, it cannot host magnetic switches.

Drives the ejector pins on a heavy plastic injection molding machine, utilizing the 2513.3 N extend force to break parts free from the mold cavity.
Positions lower dies or acts as a back gauge stop in metal fabrication press brakes, where the short riveted body conserves valuable machine bed length.
Raises and lowers heavy conveyor pallet stops in automated distribution hubs, handling loads up to the 128.1 kg vertical lift threshold safely.
When sizing this 80 mm bore actuator, consider stepping down to the SDA63, which yields 1558.6 N of push force at 0.5 MPa, or stepping up to the SDA100, which provides 3927 N at the same pressure. At 0.5 MPa, this SDA80X30H offers a safe working load of roughly 1508 N (about 60% of its rated output) and can vertically lift approximately 128.1 kg with a 2:1 safety margin.
Remember that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the load; utilize an external rod lock or pilot-operated check valve if position holding is mandatory. To order, confirm the 80 mm bore, 30 mm stroke, PT3/8 port, female rod thread, and the FKM seal specification.
Quick checklist
This double-acting 80 mm bore cylinder delivers 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. It operates between 0.15 and 1.0 MPa, runs at speeds of 30-500 mm/s, and uses a PT3/8 port.
No, this specific SKU lacks the S piston magnet, so it cannot accommodate reed or electronic switches. Additionally, it uses a fixed NBR bumper for end-of-stroke deceleration rather than a field-adjustable air cushion, so external shock absorbers are recommended for high-speed applications.
