The AirTAC AirTAC SDA80X75SB Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 75mm 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 SDA80X75SB is a double-acting, single-rod compact cylinder engineered to deliver substantial thrust within a minimal axial envelope. Utilizing a short riveted body assembly, it conserves valuable mounting depth where conventional round-body units fail to fit. At 80 mm bore, it generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa.
This specific configuration includes a built-in piston magnet (-S) for direct compatibility with AirTAC reed or electronic switches, and a male-thread piston rod (-B) sized at M22x1.5 for secure mechanical load coupling. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach speed or utilize external shock absorbers for high-energy loads. The unit operates at speeds between 30-500 mm/s and feeds via a PT3/8 port.

Drives heavy press dies for automotive body panel forming, utilizing the 2513.3 N push force to shape high-strength steel blanks securely.
Elevates loaded pallets in packaging lines, where the 75 mm stroke provides the precise vertical displacement needed for layer positioning.
Pushes finished plastic components out of injection molding tools, relying on the rigid 25 mm male-threaded rod to strike the ejector plate.
Selecting this 80 mm bore model provides a theoretical maximum push of 513 kgf at 1.0 MPa, with a computed safe working load around 1508 N (roughly 60% of the 0.5 MPa rating) and a vertical lift capacity near 128.1 kg using a 2:1 safety margin. If your application requires less force, stepping down to the SDA63 yields 1558.6 N at 0.5 MPa; conversely, escalating to the SDA100 provides 3927 N at 0.5 MPa. When ordering, confirm the 75 mm stroke, PT3/8 port, male M22x1.5 rod thread, and the required magnetic sensor option. Note that a standard compact cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates the stroke end and does not function as a locking brake, so an external rod lock or pilot-operated check valve is necessary for suspended load holding.
Quick checklist
This 80 mm bore double-acting cylinder outputs 2513.3 N push and 2267.8 N pull at 0.5 MPa, increasing to 3518.6 N push and 3175 N pull at 0.7 MPa. The theoretical maximum push is 513 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and speeds of 30-500 mm/s.
No, it uses fixed NBR bumpers at both ends to decelerate the stroke, which cannot be field-adjusted like an air cushion. Furthermore, it does not hold position if air is lost; the piston will drift. For high-speed impacts, add external shock absorbers, and for load holding, install an external rod lock or pilot-operated check valve.
