The AirTAC AirTAC SDA63X100BH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 100mm 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 SDA63X100BH is a double-acting, single-rod compact cylinder engineered for rigorous pneumatic duties. It yields 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa, operating within a 0.15-1.0 MPa pressure range. This specific SKU incorporates an FKM fluororubber seal for heightened thermal and oil resistance, alongside a male M18x1.5 piston rod thread for robust load coupling.
Its riveted body architecture drastically reduces axial mounting depth compared to conventional round-body units, saving valuable machine footprint. The 63 mm bore utilizes a PT1/4 port and a 20 mm rod to achieve a 100 mm stroke. End-stopping relies on a fixed NBR bumper to decelerate the piston near stroke limits, which is not an adjustable air cushion. Because this configuration lacks the -S magnet, it cannot host reed or electronic switches.

Drives ejection pins in plastic injection molding machines where the FKM seals withstand ambient heat and the 1558.6 N force clears finished parts reliably.
Executes 100 mm travel to fold corrugated flaps on automated packaging lines, utilizing the male M18x1.5 rod for secure mechanical linkage.
Secures heavy cast iron blocks inside CNC machining centers, taking advantage of the short riveted body to minimize interference with tool paths.
When sizing this unit, 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. The 1558.6 N output at 0.5 MPa translates to a safe working load of roughly 935 N (about 60% capacity) and a vertical lift capability of approximately 79.4 kg with a 2:1 safety margin. Ensure your ordering essentials specify the 63 mm bore, 100 mm stroke, PT1/4 port, FKM seals, and the male M18x1.5 rod end.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift. The fixed bumper only decelerates the stroke end rather than locking it. To maintain position without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 63 mm bore cylinder provides 1558.6 N push and 1401.5 N pull at 0.5 MPa, increasing to 2182.1 N push and 1962.2 N pull at 0.7 MPa. The theoretical maximum push is 318 kgf at 1.0 MPa. It operates at speeds between 30-500 mm/s.
No, this specific SKU lacks the -S piston magnet, so it cannot host reed or electronic switches. You would need the -S variant for sensing. Additionally, end-stopping relies on a fixed NBR bumper rather than an adjustable air cushion.
