The AirTAC AirTAC SDA100X50H Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 50mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA100X50H is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial envelope. Its riveted assembly significantly reduces mounting depth compared to conventional round-body units, delivering a robust 3927 N push force at 0.5 MPa. This specific SKU features fluororubber (FKM) seals for enhanced thermal and oil resistance, operating reliably across temperatures from -20 to +70 C.
Equipped with a 32 mm piston rod and PT3/8 ports, it handles substantial loads with a theoretical maximum output of 801 kgf at 1.0 MPa. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorbers. Note that this configuration omits the piston magnet, so position sensing is not supported without the -S option.

Drives heavy ejector pins on a 200-ton injection molding press, utilizing the 5497.8 N extend force at 0.7 MPa to break stubborn plastic parts free from the tool cavity.
Pushes heavy-gauge steel billets into a forming press, where the 32 mm rod withstands lateral stress and the short riveted body conserves valuable floor space on the fabrication line.
Raises 200 kg layer-forming platforms in end-of-line packaging machinery, requiring the FKM high-temperature seals to survive continuous daily thermal cycling.
When sizing this unit, evaluate your force requirements bidirectionally: stepping down to the SDA80 yields 2513.3 N push at 0.5 MPa, while the 100 mm bore offers a computed safe working load of roughly 2356 N (about 60% of its 0.5 MPa capacity) and a vertical lift capacity near 200.2 kg with a 2:1 safety margin. If your mechanism must maintain vertical position during air loss or valve centering, be aware that the piston will drift; the fixed bumper only slows the end of travel and does not act as a lock, so an external rod lock or pilot-operated check valve is necessary for holding.
To finalize your order, confirm the 100 mm bore, 50 mm stroke, PT3/8 porting, and the female M18x1.5 rod-end thread. This variant includes FKM seals (-H) but lacks the -S magnet and -B male thread; choose those suffixes if your application requires solid-state or reed sensing and alternate load coupling.
Quick checklist
At 0.5 MPa, the push force is 3927 N and the pull force is 3524.9 N. At 0.7 MPa, the push force is 5497.8 N and the pull force is 4934.8 N. The theoretical maximum push is 801 kgf at the maximum operating pressure of 1.0 MPa.
No, the piston will drift downward if air is lost or the valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end and does not function as a braking lock. To maintain vertical position, you must install an external rod lock or a pilot-operated check valve.
