The AirTAC AirTAC SDA80X80S Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 80mm 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 SDA80X80S is a double-acting single-rod compact cylinder engineered for high-force tasks within a minimal axial footprint. It generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa, utilizing a hard-anodized 80 mm bore and a sturdy 25 mm piston rod. Because the body is riveted rather than constructed with long tie rods, it drastically reduces overall mounting length in tight machinery.
This unit includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning external shock absorbers should be added for high-energy loads. The 80 mm stroke operates at speeds between 30 and 500 mm/s via PT3/8 ports.

Drives ejection pins on a 150-ton injection molding press where the 2513.3 N push force clears heavy plastic parts within a shallow mold base.
Indexes heavy steel blanks into a forming press, leveraging the 25 mm rod and 128.1 kg vertical lift margin to push stock reliably.
Raises loaded machining pallets vertically, using the built-in magnet and an electronic switch to confirm the 80 mm stroke endpoint for the loader.
When sizing this unit, compare its 2513.3 N push at 0.5 MPa against adjacent bores: stepping down to the SDA63 yields 1558.6 N, while stepping up to the SDA100 provides 3927 N. Based on the 0.5 MPa rating, a safe working load is approximately 1508 N (about 60% capacity), translating to a vertical lift capability of roughly 128.1 kg with a 2:1 safety margin. To finalize your order, confirm the 80 mm bore, 80 mm stroke, PT3/8 porting, female M14x1.5 rod thread, and the required -S magnet.
Remember that a standard double-acting cylinder will not hold a load if air pressure drops or the valve is centered; the piston will drift, and the fixed NBR bumper only slows it near the stroke end. If your application requires static holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this double-acting cylinder provides 2513.3 N push and 2267.8 N pull. At 0.7 MPa, push increases to 3518.6 N. The theoretical maximum push is 513 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the piston near stroke completion. It is not an adjustable air cushion. For high-speed or high-energy cycles, you should slow the approach or add external shock absorbers.
