The AirTAC AirTAC SDA80X45SB Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 45mm 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 SDA80X45SB is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Utilizing a riveted body assembly, it significantly reduces mounting depth compared to conventional round-body units while delivering a robust 2513.3 N push force at 0.5 MPa. The 80 mm bore houses a 25 mm hard-anodized piston rod, and this specific configuration includes a male M22x1.5 thread for secure mechanical load coupling.
Equipped with an integrated piston magnet (-S), the body is designed to accept AirTAC reed or electronic switches along its peripheral grooves for precise position sensing. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should reduce approach speeds or utilize external shock absorbers for high kinetic energy loads. Operating at speeds between 30-500 mm/s, it provides a safe working load of roughly 1508 N (about 60% of the 0.5 MPa output) and a vertical lift capacity of approximately 128.1 kg with a 2:1 safety margin.

Drives heavy ejector pins in plastic injection molding machinery where the short riveted body minimizes interference with the mold base while providing 2513.3 N of extension force.
Lifts and positions heavy stamping dies on guided rails, utilizing the male M22x1.5 rod end for rigid coupling and the fixed NBR bumper to soften the 45 mm stroke termination.
Indexes empty wooden pallets into high-speed packaging lines, relying on the built-in magnet to trigger reed or electronic switches for confirming load transfer.
When sizing this 80 mm bore actuator, evaluate your force requirements carefully. Stepping down, the SDA63 provides 1558.6 N of push at 0.5 MPa, whereas stepping up to the massive SDA100 yields 3927 N at the same pressure. This SDA80X45SB configuration is ordered with a 45 mm stroke, PT3/8 port, a built-in sensor magnet, and a male M22x1.5 rod end. Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift. If your application requires static position holding, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This 80 mm bore double-acting cylinder generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa. At 0.7 MPa, the push increases to 3518.6 N and pull to 3175 N. The theoretical maximum push force is 513 kgf at 1.0 MPa.
No, it uses fixed NBR bumpers at both ends to decelerate the stroke, which are not field-adjustable; for high-energy impacts, add an external shock absorber. Additionally, the -B option means it has a male M22x1.5 piston rod thread instead of the standard female M14x1.5.
