The AirTAC AirTAC SDA80X120SB Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 120mm 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 SDA80X120SB is a double-acting, single-rod compact cylinder engineered to deliver a substantial 2513.3 N push force at 0.5 MPa. Its riveted body design integrates the barrel, rear cover, piston, and rod into a highly unified assembly, drastically reducing axial mounting depth compared to conventional round-body units. This space-saving footprint is critical when designing large-scale machinery with tight clearances. Equipped with a built-in piston magnet, the body is ready to accept AirTAC reed or electronic switches along its peripheral grooves for precise end-of-stroke detection.
This specific configuration includes a male M22x1.5 threaded piston rod end, providing a robust mechanical coupling for heavy payloads. The unit operates at speeds between 30-500 mm/s and relies on a fixed NBR bumper at each end to decelerate the stroke. Because this bumper is not an adjustable air cushion, operators should slow the approach or utilize external shock absorbers for high-energy cycles. The 80 mm bore utilizes a PT3/8 port and a 25 mm rod to handle demanding actuation tasks.

Provides the heavy 2513.3 N push stroke required to eject dense plastic components from large injection molding tools, utilizing the male M22x1.5 thread for secure mold mounting.
Actuates heavy diverting arms on automated packaging conveyors, where the 120 mm stroke shifts loaded pallets laterally without consuming excessive machine footprint.
Lifts heavy steel coil blanks into stamping presses, offering a safe vertical lift capacity of roughly 128.1 kg with a 2:1 margin while fitting into compact press feed enclosures.
When sizing this 80 mm bore actuator, consider stepping down to the SDA63, which yields 1558.6 N of push force at 0.5 MPa, or stepping up to the SDA100, which provides 3927 N at the same pressure. The SDA80X120SB offers a computed safe working load of roughly 1508 N (about 60% of its 0.5 MPa capacity) and a vertical lift capability of approximately 128.1 kg with a 2:1 safety margin. To finalize your order, confirm the 80 mm bore, 120 mm stroke, PT3/8 port, male M22x1.5 rod thread, and the built-in magnet. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; if your application requires strict load holding, you must integrate an external rod lock or a pilot-operated check valve.
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. The theoretical maximum push force is 513 kgf at the 1.0 MPa operating pressure limit.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion; for high-speed cycles, external shock absorbers are recommended. The built-in -S magnet allows you to mount AirTAC reed or electronic switches directly into the body grooves for position detection.
