The AirTAC AirTAC SDA80X35BH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 35mm 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 SDA80X35BH is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted body assembly significantly reduces mounting depth compared to conventional round-body units, delivering a robust 2513.3 N push force at 0.5 MPa. This specific SKU includes a male M22x1.5 piston rod end for secure mechanical load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
Built around an 80 mm bore with a 25 mm rod, the hard-anodized inner wall ensures long service life. End-stop deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycles. Note that this configuration omits the piston magnet, so position sensing is not supported without switching to an -S variant.

Drives heavy ejector pins on a 150-ton injection molding press, utilizing the 2513.3 N extend force to break plastic parts free from deep cavity molds.
Indexes heavy sheet metal blanks into a multi-station transfer die, relying on the short riveted body to fit within tight press column clearances.
Raises 120 kg corrugated carton stacks via a male M22x1.5 rod coupling, benefiting from the FKM seals in high-friction warehouse environments.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA63 yields 1558.6 N of push at 0.5 MPa, whereas moving up to the SDA100 provides 3927 N. For the SDA80X35BH, the safe working load is approximately 1508 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 128.1 kg with a 2:1 safety margin. Keep in mind that a standard double-acting 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. If your application demands strict position holding, you must integrate an external rod lock or a pilot-operated check valve. Ensure your ordering essentials match this exact configuration: 80 mm bore, 35 mm stroke, PT3/8 port, male M22x1.5 rod thread, FKM seals, and no sensor magnet.
Quick checklist
At 0.5 MPa, the push force is 2513.3 N and the pull force is 2267.8 N. 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, this specific SKU does not have a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need the -S option for position sensing. Additionally, end-of-stroke deceleration is handled by a fixed NBR bumper, not an adjustable air cushion.
