The AirTAC AirTAC SDA50X5H 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 SDA50X5H is a double-acting, single-rod compact cylinder engineered for tight axial spaces. It generates 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. This specific SKU features an FKM (fluororubber) seal variant, providing enhanced resistance to higher temperatures and oily environments compared to standard NBR. The 5 mm stroke is ideal for micro-clamping tasks.
Its riveted body assembly significantly reduces overall mounting length compared to round-body alternatives. The 50 mm bore utilizes a PT1/4 port and a 20 mm piston rod. End-of-stroke deceleration is handled by a fixed NBR bumper, which is not an adjustable air cushion. Because this configuration lacks the -S option, it has no piston magnet and cannot support magnetic position sensing.

Uses the 5 mm stroke to rapidly secure small aluminum workpieces inside machining centers, leveraging the 981.7 N push force to prevent part shift during milling.
Deploys the short 5 mm stroke to fold corrugated cardboard flaps on high-speed packaging lines, where the FKM seals withstand occasional lubrication overspray.
Ejects small molded plastic parts from press dies, using the compact riveted body to fit within dense tooling layouts where axial depth is strictly limited.
When sizing this actuator, evaluate your force margins carefully. Stepping down to the SDA40 yields 628.3 N of push at 0.5 MPa, while stepping up to the SDA63 provides 1558.6 N. At 981.7 N push, this 50 mm bore achieves a safe working load of roughly 589 N (about 60% capacity) and can vertically lift approximately 50 kg with a 2:1 safety margin. To order, confirm the 50 mm bore, 5 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the FKM seal requirement. Note that a plain cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates near stroke end and does not function as a locking brake. For secure load holding, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 50 mm bore double-acting cylinder provides 981.7 N push and 824.7 N pull at 0.5 MPa, 1374.4 N push and 1154.5 N pull at 0.7 MPa, with a theoretical maximum push of 200 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, speed is 30-500 mm/s, and it uses a PT1/4 port.
No, this specific SKU lacks the -S option, meaning it has no piston magnet and cannot trigger AirTAC reed or electronic switches. The body retains the standard sensor grooves, but you must select the -S variant to enable position sensing.
