The AirTAC AirTAC SDA63X75S 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 SDA63X75S is a double-acting, single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into an exceptionally short axial package, saving valuable mounting depth where a traditional round-body unit would not fit.
This specific model includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning external shock absorbers should be added for high-energy cycles. The 20 mm rod and PT1/4 port are set by the 63 mm bore.

Drives heavy corrugated cartons onto outbound pallets in packaging lines, utilizing the 1558.6 N extend force to shift loads reliably without exceeding axial machine limits.
Acts as a rugged, space-saving back-gauge stop in metal forming, where the fixed NBR bumper absorbs the repeated end-stroke impacts of rapid positioning.
Raises and lowers a 70 kg machining access gate, safely operating within the computed 79.4 kg vertical lift capacity at a 2:1 safety margin.
When sizing this actuator, stepping down to the SDA50 yields 981.7 N of push at 0.5 MPa, while stepping up to the SDA80 provides 2513.3 N, allowing you to scale your drive force precisely. Based on the 0.5 MPa figure, a safe working load is roughly 935 N (about 60 percent capacity), translating to a vertical lift capability of approximately 79.4 kg with a 2:1 safety margin.
Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end and acts as no lock or brake. To secure a suspended load, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 63 mm bore, 75 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the required magnetic sensor option.
Quick checklist
At 0.5 MPa, this 63 mm bore cylinder provides 1558.6 N of push and 1401.5 N of pull. At 0.7 MPa, push increases to 2182.1 N. The theoretical maximum push is 318 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. Additionally, it does not hold its position if air is lost; the piston will drift, so an external rod lock or pilot-operated check valve is required for load holding.
