The AirTAC AirTAC SDA80X75 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 SDA80X75 is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. It delivers a robust 2513.3 N push force at 0.5 MPa, utilizing a hard-anodized 80 mm bore and a sturdy 25 mm piston rod. The short riveted body design significantly reduces overall mounting length compared to traditional round-body actuators, making it highly effective for machinery where space is strictly limited.
This model operates at speeds between 30-500 mm/s and relies on a fixed NBR bumper at each end to absorb impact energy. Because it lacks an adjustable air cushion, operators should incorporate external shock absorbers or decelerate the approach speed when cycling heavy loads at high velocities. The base SKU ships without a piston magnet, meaning position sensing via reed or electronic switches is not supported unless upgraded to the -S variant.

Drives heavy press dies and forms metal body panels, utilizing the 2513.3 N extend force to shape high-tensile steel within a tight machine enclosure.
Elevates loaded pallets in high-throughput packaging lines, where the 25 mm rod and 75 mm stroke provide stable vertical actuation under dynamic loads.
Pushes finished plastic components out of heavy molds, relying on the hard-anodized bore to withstand repetitive high-impact ejection cycles.
When sizing this 80 mm bore actuator, evaluate your force requirements carefully. Stepping down, the SDA63 provides 1558.6 N of push force at 0.5 MPa, whereas stepping up to the SDA100 yields 3927 N. The SDA80X75 strikes a balance, offering a safe working load of roughly 1508 N (about 60 percent of its 0.5 MPa rating) and a vertical lift capacity near 128.1 kg with a 2:1 safety margin. Ensure your configuration specifies the PT3/8 port, the 75 mm stroke, the female M14x1.5 rod-end thread, and explicitly notes the absence of the magnet option.
Remember that a standard compact cylinder cannot hold a load if air pressure drops or the directional valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the rod near the stroke endpoints rather than locking it. If your application demands static position holding, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This 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 is 513 kgf at the 1.0 MPa operating pressure limit.
This specific SKU lacks the piston magnet, so it cannot support reed or electronic switches unless you specify the -S option. Additionally, it uses a fixed NBR bumper for end-stop deceleration rather than an adjustable air cushion, so external shock absorption is recommended for high-energy cycles.
