The AirTAC AirTAC SDA50X10H Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 10mm 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 SDA50X10H is a double-acting single-rod compact cylinder engineered for tight axial spaces. It delivers 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. With a 50 mm bore and 10 mm stroke, the riveted body design drastically reduces mounting depth where a conventional round-body unit would not fit.
The bore inner wall is hard-anodized for durability, and the piston utilizes a two-way seal. End-stop deceleration is handled by a fixed NBR bumper at each end, which is not field-adjustable. Because this configuration lacks the -S magnet option, it cannot support magnetic position sensing. The 20 mm piston rod terminates in a female M10x1.5 thread, and the air supply connects via PT1/4 ports.

Drives short 10 mm folding strokes on packaging lines, using its 981.7 N thrust to tuck heavy cardboard flaps before taping, even in ambient heat near sealing ovens due to the FKM seal.
Deploys dowel pins into machined aluminum housings on an assembly fixture, leveraging the 50 mm bore force while keeping the overall machine footprint shallow.
Ejects molded rubber parts from a hot press, where the fluororubber seals withstand residual heat and the compact body mounts flush to the press platen.
When sizing this actuator, evaluate your force requirements against its 981.7 N push capability at 0.5 MPa. A safe working load is approximately 589 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 50 kg with a 2:1 safety margin. If your application demands less force, the smaller SDA40 bore provides 628.3 N of push at 0.5 MPa. Conversely, stepping up to the SDA63 bore yields 1558.6 N at 0.5 MPa for heavier payloads.
To finalize your order, confirm the 50 mm bore, 10 mm stroke, PT1/4 port thread, female M10x1.5 rod end, and the FKM seal option. Note that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the load. For vertical positioning that must be maintained without live pressure, an external rod lock or pilot-operated check valve is required.
Quick checklist
This 50 mm bore double-acting 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. It operates on filtered air at 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
No, this specific SKU does not include the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to select the -S variant for position sensing. Additionally, end-stop deceleration relies on a fixed NBR bumper, not an adjustable air cushion.
