The AirTAC AirTAC SDA63X30BH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 30mm 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 SDA63X30BH is a double-acting single-rod compact cylinder engineered for tight axial footprints. Its riveted body design significantly shortens overall length compared to round-body units, delivering 1558.6 N of push force at 0.5 MPa. This specific SKU features a male M18x1.5 piston rod thread for robust load coupling and FKM seals for enhanced thermal and oil resistance.
The bore inner wall is hard-anodized to reduce wear, while a fixed NBR bumper at each end decelerates the piston near stroke limits. Note that this configuration omits the piston magnet, so it cannot directly host AirTAC reed or electronic switches. Operating pressure spans 0.15-1.0 MPa with a speed range of 30-500 mm/s.

Drives ejection pins in plastic injection molding machines where FKM seals withstand elevated ambient heat and the male M18x1.5 rod secures heavy tooling fixtures.
Folds corrugated cardboard flaps on high-speed packaging lines, utilizing the short 30 mm stroke and 1558.6 N force to cleanly crease heavy-duty material.
Positions sheet metal blanks in progressive stamping presses, taking advantage of the compact riveted body to minimize interference in cramped die clamping spaces.
When sizing this unit, verify if the 63 mm bore is optimal for your pneumatic setup. Stepping down to the SDA50 yields 981.7 N of push at 0.5 MPa, whereas stepping up to the SDA80 provides 2513.3 N. Based on the 1558.6 N output at 0.5 MPa, the computed safe working load is roughly 935 N (about 60% capacity), translating to a vertical lift capability of approximately 79.4 kg with a 2:1 safety margin.
Ensure your ordering essentials match the SDA63X30BH: 63 mm bore, 30 mm stroke, PT1/4 port, male M18x1.5 rod thread, FKM seals, and no sensor magnet. Because a standard cylinder does not hold position upon air loss or valve centering—the piston drifts and the fixed bumper only decelerates near the end of travel—an external rod lock or pilot-operated check valve is required for suspended loads.
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, which is the maximum operating pressure.
It relies on a fixed NBR bumper at each end to decelerate the piston near the stroke extremes; it is not an adjustable air cushion. Furthermore, it is not a locking device—if air is lost or the valve is centered, the piston will drift, so an external rod lock or pilot-operated check valve is necessary to hold a load.
