The AirTAC AirTAC SDA63X75 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 SDA63X75 is a double-acting single-rod compact cylinder engineered to deliver 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly shortened unit, drastically reducing axial mounting depth where a conventional round-body actuator would be too bulky. The 63 mm bore houses a hard-anodized inner wall and a two-way piston seal for reliable service.
This specific configuration features a 75 mm stroke, a 20 mm piston rod, and PT1/4 air ports. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycles. Because this SKU lacks the -S magnet code, it cannot host magnetic switches for position sensing.

Provides the 1558.6 N push required to eject dense plastic parts from injection molding tools within a tight press footprint.
Raises layered product stacks in end-of-line packaging machinery, safely handling loads near the 79.4 kg vertical lift threshold.
Actuates upper die assemblies in light-gauge metal forming equipment where a short 75 mm stroke and compact depth are essential.
When sizing this model, compare its 1558.6 N push at 0.5 MPa against adjacent bores: the SDA50 offers 981.7 N if you need a lighter footprint, while the SDA80 provides 2513.3 N for heavier demands. For this 63 mm bore, a practical safe working load is roughly 935 N (about 60% of the 0.5 MPa push figure), translating to a vertical lift capacity of approximately 79.4 kg with a 2:1 safety margin.
To finalize your order, confirm the 63 mm bore, 75 mm stroke, PT1/4 porting, and the female M10x1.5 rod-end thread. Note that a standard SDA does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only slows it near the stroke end. For suspended loads, 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 and the pull force is 1962.2 N. The theoretical maximum push force is 318 kgf at 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot host reed or electronic switches. You must select the -S option code variant to enable position sensing along the body grooves.
