The AirTAC AirTAC SDA50X5N 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 SDA50X5N is a double-acting single-rod compact cylinder engineered for minimal axial mounting depth. By utilizing a short riveted body that joins the barrel, rear cover, and piston, it achieves a highly space-efficient footprint where a conventional round-body unit would not fit. It delivers a robust 981.7 N of push force and 824.7 N of pull force at 0.5 MPa, operating at speeds between 30-500 mm/s.
This specific configuration features a 50 mm bore, a 5 mm stroke, and a 20 mm piston rod with a female M10x1.5 thread. The bore is hard-anodized for longevity, while end-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this SKU lacks a piston magnet, so it cannot support magnetic sensing without upgrading to the -S variant.

Ideal for popping machined aluminum components out of CNC fixtures using a quick 5 mm travel, leveraging the 981.7 N push force to break coolant suction.
Provides a compact riveted-body solution for tucking corrugated cardboard flaps on a packaging line where axial mounting space is severely restricted.
Delivers the necessary 50 kg vertical lift margin to seat dowel pins into blind holes on an assembly jig without requiring a tall profile cylinder.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA40 reduces the 0.5 MPa push capacity to 628.3 N, whereas stepping up to the SDA63 increases it significantly to 1558.6 N. For the SDA50X5N, the computed safe working load is approximately 589 N (about 60% of the 981.7 N figure), allowing a vertical lift of roughly 50 kg with a 2:1 safety margin. Confirm your ordering essentials: 50 mm bore, 5 mm stroke, PT1/4 port, female rod thread, and no sensor magnet.
Keep in mind that a plain double-acting cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift. The fixed NBR bumper only decelerates the load near the stroke end and does not function as a lock or brake. If your application requires position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 981.7 N and the pull force is 824.7 N. At 0.7 MPa, the push force is 1374.4 N and the pull force is 1154.5 N. The theoretical maximum push force is 200 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and the operating temperature spans -20 to +70 C.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. To enable position sensing, you must specify the -S option. Additionally, end-stop deceleration relies on a fixed NBR bumper, which is not an adjustable air cushion.
