The AirTAC AirTAC SDA80X90 Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 90mm 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 SDA80X90 is a double-acting single-rod compact cylinder engineered to deliver a substantial 2513.3 N push force at 0.5 MPa. Its riveted assembly joins the barrel, rear cover, piston and rod into a highly abbreviated unit, drastically reducing axial mounting depth compared to conventional round-body actuators. The hard-anodized bore minimizes friction while the integrated fixed NBR bumpers absorb end-stop impact.
This 80 mm bore model features a robust 25 mm piston rod and PT3/8 air ports. It lacks a piston magnet, meaning it cannot host magnetic switches in this base configuration. Operating at speeds of 30-500 mm/s, the unit relies strictly on its fixed rubber bumpers for end-of-stroke deceleration rather than an adjustable air cushion.

Drives heavy bearing housings into automotive transmission casings, utilizing the 2513.3 N push force to seat components firmly without requiring excessive axial machine footprint.
Ejects dense plastic pallets from molding machines, where the 90 mm stroke and 25 mm rod provide the necessary reach and rigidity to safely strip finished parts from deep tooling.
Raises and lowers heavy conveyor diverters in distribution hubs, safely handling loads up to 128.1 kg vertically thanks to the robust 80 mm bore architecture.
When sizing this actuator, evaluate your force requirements carefully. Stepping down, the SDA63 provides 1558.6 N of push at 0.5 MPa, while stepping up to the SDA100 yields 3927 N at the same pressure. For this SDA80X90 configuration, the safe working load is approximately 1508 N (about 60% of the 2513.3 N figure), allowing a vertical lift of roughly 128.1 kg with a 2:1 safety margin. Confirm your ordering essentials: 80 mm bore, 90 mm stroke, PT3/8 port, female rod thread (M14x1.5), and no magnet.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered. The fixed NBR bumper only decelerates the piston near the stroke limits; it does not function as a locking brake. If your application demands strict position holding under load loss, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 1.0 MPa operating pressure limit.
This specific SKU lacks the internal piston magnet, so it cannot accept reed or electronic switches without upgrading to the -S variant. Additionally, it uses fixed NBR bumpers for end-stop deceleration, not an adjustable air cushion, so external shock absorbers are recommended for high-energy loads.
