The AirTAC AirTAC SDA80X80SB 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 SDA80X80SB is a double-acting single-rod compact cylinder engineered for high-force tasks in tight axial spaces. It delivers a substantial 2513.3 N push and 2267.8 N pull at 0.5 MPa, utilizing a hard-anodized 80 mm bore and a robust Ø25 mm piston rod. The riveted body design drastically reduces overall mounting length compared to conventional round-body units, saving valuable machine footprint.
This specific configuration includes an S option for a built-in piston magnet, enabling seamless integration with AirTAC reed or electronic switches via the body's peripheral grooves. The B option equips the rod with a male M22x1.5 thread for secure mechanical coupling. Deceleration at stroke ends is handled by a fixed NBR bumper, which is not an adjustable air cushion, so high-energy cycles may require external shock absorption.

Drives small bronze bushings into automotive gearbox housings, utilizing the 2513.3 N extend force to seat components flush against machined shoulders.
Actuates a heavy gravity-feed pallet chute gate in a high-throughput distribution center, where the short 80 mm stroke and male M22x1.5 rod securely lift the steel barrier.
Provides auxiliary ejection force for a large plastic injection mold, pushing a 128.1 kg tooling insert out of the cavity at a controlled 30-500 mm/s speed range.
When sizing this 80 mm bore unit, consider stepping down to the SDA63, which provides 1558.6 N of push force at 0.5 MPa, or moving up to the SDA100, which yields 3927 N at the same pressure. The SDA80X80SB provides a safe working load of roughly 1508 N (about 60% of its 0.5 MPa capacity) and can vertically lift approximately 128.1 kg with a 2:1 safety margin. Ensure your ordering essentials are correct: 80 mm bore, 80 mm stroke, PT3/8 ports, male M22x1.5 rod thread, and the integrated sensor magnet.
Keep in mind that a standard compact cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed NBR bumper only decelerates the stroke near its limits. If your application requires load holding without live pressure, you must incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this 80 mm bore cylinder outputs 2513.3 N of push force and 2267.8 N of pull force. At 0.7 MPa, the push increases to 3518.6 N and the pull to 3175 N. The theoretical maximum push force is 513 kgf at 1.0 MPa.
No, the SDA80X80SB uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion. For high-speed or high-energy cycles, you should slow the approach speed or add an external shock absorber to prevent damage.
