The AirTAC AirTAC SDA50X5B Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 5mm 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 SDA50X5B is a double-acting, single-rod compact cylinder engineered for minimal axial mounting depth. By utilizing a riveted body assembly rather than a standard round-body design, it drastically reduces machine footprint while delivering a robust 981.7 N push force at 0.5 MPa. This specific configuration features a 5 mm stroke and a male M18x1.5 piston rod end for direct load coupling.
The unit relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot support magnetic reed or electronic switches. Operating at speeds between 30-500 mm/s, the hard-anodized 50 mm bore ensures durability for high-cycle positioning tasks.

Ideal for driving a short 5 mm embossing or stamping action in sheet metal fabrication, utilizing the 981.7 N extend force to mark components securely.
Provides a quick, shallow push to fold minor carton flaps on a packaging line, where the compact riveted body prevents interference with conveyor guides.
Acts as a short-range ejector in injection molding cells, using the male M18x1.5 thread to securely attach a customized knock-out pin for part release.
When sizing this actuator, consider stepping down to the SDA40, which provides 628.3 N of push at 0.5 MPa, or moving up to the SDA63, which yields 1558.6 N at the same pressure. For the SDA50X5B, the computed safe working load is approximately 589 N (about 60% of the 981.7 N figure), translating to a vertical lift capacity of roughly 50 kg with a 2:1 safety margin. Ensure you specify the PT1/4 port, the 5 mm stroke, and the male M18x1.5 rod thread when ordering.
Note that a standard compact cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end rather than locking the load. If your application requires position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 50 mm bore cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa, and 1374.4 N push at 0.7 MPa. The theoretical maximum push force is 200 kgf at 1.0 MPa, with a maximum operating pressure of 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot trigger reed or electronic switches. You would need the -S option variant for sensing capabilities, and detection is purely mechanical without it.
