The AirTAC AirTAC SDA63X80 Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 80mm stroke, PT1/4 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA63X80 is a double-acting single-rod compact cylinder engineered to deliver a robust 1558.6 N push and 1401.5 N pull at 0.5 MPa. Its riveted assembly securely joins the barrel, rear cover, piston, and rod, drastically reducing overall axial length to save machine footprint where a longer round-body unit would fail to fit. The 63 mm bore features a hard-anodized inner wall and a 20 mm piston rod.
This specific SKU operates without a piston magnet and therefore cannot support position sensing. End-stop energy is managed strictly by a fixed NBR bumper at each end, which decelerates the piston near stroke limits but is not an adjustable air cushion. Operating speed spans 30-500 mm/s, and the PT1/4 air ports supply the volume needed for rapid cycling.

Provides the 1558.6 N push force required to eject dense plastic parts from injection molds, utilizing the short riveted body to fit within tight mold voids.
Drives the folding mechanism on automated carton erectors, moving the 20 mm rod at 30-500 mm/s to seal large corrugated cases efficiently.
Presses bearings into automotive housings on a transfer line, where the fixed NBR bumper absorbs the end-stop impact during repetitive high-frequency strokes.
When sizing this actuator, stepping down to the SDA50 yields 981.7 N of push force at 0.5 MPa, while stepping up to the SDA80 provides 2513.3 N. For this 63 mm bore, a safe working load is approximately 935 N (about 60% of the 1558.6 N figure), allowing a vertical lift of roughly 79.4 kg with a 2:1 safety margin. To finalize your order, confirm the 80 mm stroke, PT1/4 porting, female M10x1.5 rod-end thread, and the absence of the magnet option. Note that a standard 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 lock or brake. To hold a load securely without live pressure, an external rod lock or pilot-operated check valve is required.
Quick checklist
At 0.5 MPa, the push force is 1558.6 N and the pull force is 1401.5 N. At 0.7 MPa, push is 2182.1 N and pull is 1962.2 N. The theoretical maximum push is 318 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU is manufactured without a piston magnet, so it cannot support reed or electronic switches. You must select the -S option code variant to enable sensing. Additionally, end-stop deceleration relies solely on a fixed NBR bumper, not an adjustable cushion.
