The AirTAC AirTAC SDA40X80H Compact Cylinder | 40mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 80mm stroke, PT1/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA40X80H is a double-acting single-rod compact cylinder featuring a 40 mm bore and an 80 mm stroke. It generates 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. The riveted body design significantly reduces axial mounting depth compared to round-body alternatives, making it highly effective for machinery where space footprint is critical. This H variant utilizes a fluororubber (FKM) seal for enhanced thermal and oil resistance.
The bore inner wall is hard-anodized for longevity, and end-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Because this specific SKU lacks the S option, it has no piston magnet and cannot support position sensing. The 16 mm piston rod uses an M8x1.25 female thread end, and the fluid port is PT1/8.

Secures aluminum workpieces inside CNC machining centers. The FKM seal handles coolant spray, while the short body keeps the fixture profile low.
Pushes formed plastic bottles off a continuous motion blow molding line. The 628.3 N extension force reliably clears the mold halves without requiring a large footprint.
Actuates a routing flap on a high-speed logistics conveyor to sort heavy wooden pallets. The 80 mm stroke provides sufficient travel to redirect the flow.
When sizing this actuator, evaluate stepping down to the SDA32 which yields 402.1 N push at 0.5 MPa, or moving up to the SDA50 which provides 981.7 N push at 0.5 MPa. Based on the 628.3 N output at 0.5 MPa, a safe working load is approximately 377 N (60 percent capacity), translating to a vertical lift capability of roughly 32 kg with a 2:1 safety margin. Ensure your ordering essentials cover the 40 mm bore, 80 mm stroke, PT1/8 port, FKM seal, and the standard female rod thread.
Keep in mind that a standard compact cylinder will not hold a load if air pressure drops or the directional valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the stroke near its end without acting as a mechanical lock. If your application requires static load holding, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This 40 mm bore double-acting cylinder outputs 628.3 N push and 527.8 N pull at 0.5 MPa, or 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum push force is 128 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
No, this specific SKU does not include the S option, meaning it lacks a piston magnet and cannot trigger AirTAC reed or electronic switches. To add sensing capabilities, you would need to specify the SDA40X80HS variant. Additionally, this model uses a fixed NBR bumper for end-stop deceleration, not an adjustable cushion.
