The AirTAC AirTAC SDA80X80B 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 SDA80X80B 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 short axial package, saving valuable mounting depth where a traditional round-body actuator would be too bulky. The hard-anodized bore and two-way piston seal ensure durable performance within the 0.15-1.0 MPa operating pressure range.
This specific SKU includes the B option, meaning it features a male M22x1.5 threaded piston rod for robust load coupling, rather than the default female M14x1.5 thread. End-of-stroke deceleration is handled by a fixed NBR bumper at each end, which absorbs impact energy but is not a field-adjustable air cushion. Because this unit lacks the S magnet code, it cannot host AirTAC reed or electronic switches.

Drives heavy mold ejection plates in plastic injection machinery where the short riveted body minimizes axial footprint and the male M22x1.5 rod secures the heavy ejector assembly.
Indexes thick metal stock into a mechanical stamping press, utilizing the 2513.3 N push force at 0.5 MPa to move heavy coils reliably against resistance.
Actuates heavy lift gates on automated palletizing lines, where the fixed NBR bumpers absorb the substantial kinetic energy generated by moving 128 kg vertical loads.
When sizing this 80 mm bore actuator, consider stepping down to the SDA63, which provides 1558.6 N of push force at 0.5 MPa, or stepping up to the SDA100, which yields 3927 N at the same pressure. For this SDA80X80B model, the safe working load is approximately 1508 N (about 60% of the 0.5 MPa push figure), allowing a vertical lift of roughly 128.1 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed NBR bumper only decelerates the stroke end rather than locking the load; an external rod lock or pilot-operated check valve is required to hold a vertical load safely. To order, confirm the 80 mm bore, 80 mm stroke, PT3/8 port, male M22x1.5 rod thread, and the absence of a piston magnet.
Quick checklist
The SDA80X80B generates a push force of 2513.3 N and a pull force of 2267.8 N at 0.5 MPa. At 0.7 MPa, the push force is 3518.6 N. The theoretical maximum push force is 513 kgf at the maximum operating pressure of 1.0 MPa.
No, end-of-travel damping is provided solely by fixed NBR bumpers that decelerate the piston, not by an adjustable air cushion. Additionally, this SKU lacks the S magnet option, so it cannot support reed or electronic switches; you must select an SDA80x80S variant for position sensing.
