The AirTAC AirTAC SDA63X75H Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 75mm 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 SDA63X75H is a double-acting, single-rod compact cylinder engineered with a 63 mm bore and a 75 mm stroke. The riveted assembly keeps the total axial length exceptionally short, minimizing machine footprint where a conventional round-body unit would be too deep. Equipped with a fluororubber (FKM) seal, this variant provides enhanced resistance to higher temperatures and oil exposure compared to the standard NBR configuration.
Operating at 0.15-1.0 MPa, it generates a push force of 1558.6 N and a pull force of 1401.5 N at 0.5 MPa. The hard-anodized bore houses a fixed NBR bumper at each end to decelerate the piston near stroke limits. Since this specific SKU lacks the -S magnet option, it cannot directly mount AirTAC reed or electronic switches.

Provides the robust 1558.6 N extension force needed to eject dense plastic components from molding machines, while the FKM seals withstand ambient heat near the mold plates.
Drives heavy cardboard flaps down on high-speed packaging lines prior to strapping, utilizing the 75 mm stroke to clear the path for incoming product.
Pushes metal blanks into a stamping die where the short riveted body saves critical axial depth on a crowded press bed.
When sizing this actuator, evaluate your neighbors: 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 capacity), translating to a vertical lift capability of roughly 79.4 kg with a 2:1 safety margin. Confirm your ordering essentials: 63 mm bore, 75 mm stroke, PT1/4 port, female M10x1.5 rod thread, and FKM seals.
Note that a standard compact cylinder does not hold its position when air pressure is lost or the directional valve is centered. The piston will drift, and the fixed bumper only decelerates the stroke end rather than locking the load. If your application requires position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
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, the push force is 2182.1 N. The theoretical maximum push force is 318 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU does not include the -S piston magnet, so it cannot support AirTAC reed or electronic switches. You would need to order the -S variant for position sensing. Additionally, it relies on a fixed NBR bumper for end-stop deceleration, not an adjustable air cushion.
