The AirTAC AirTAC SDA63X120 Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 120mm 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 SDA63X120 is a double-acting, single-rod compact cylinder engineered to deliver 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa. Featuring a 63 mm bore and 120 mm stroke, this unit relies on a short riveted body that drastically reduces axial mounting depth compared to conventional round-body actuators. The hard-anodized bore and two-way piston seal ensure reliable service within the 0.15-1.0 MPa operating pressure range.
This specific configuration lacks a piston magnet, meaning it cannot support AirTAC reed or electronic switches. End-of-travel deceleration is handled strictly by fixed NBR bumpers rather than an adjustable air cushion. Operating at speeds between 30 and 500 mm/s, the 20 mm piston rod utilizes a female M10x1.5 thread, requiring careful alignment to avoid side loading on the compact rod assembly.

Secures heavy cast iron engine blocks onto CNC machining centers. The 1558.6 N extend force at 0.5 MPa provides rigid holding against 120 mm of travel without overwhelming the machine's footprint.
Actuates a routing gate on a 24V DC roller conveyor. The compact riveted body fits within the 63 mm side-frame gap, while the 120 mm stroke fully retracts the gate for pallet passage.
Folds heavy-duty corrugated side flaps on a continuous carton sealing line. Operating at 30-500 mm/s, the fixed NBR bumpers absorb the impact of folding thick double-wall board at high cycle rates.
Selecting this 63 mm bore actuator involves comparing your actual load requirements against its neighboring sizes. If you need less force, stepping down to the SDA50 provides 981.7 N of push at 0.5 MPa. Conversely, scaling up to the SDA80 yields 2513.3 N at the same pressure. For the SDA63X120 specifically, the computed safe working load is approximately 935 N (about 60% of the 1558.6 N figure), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin.
When integrating this model, remember 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 acts as neither a lock nor a brake. For applications requiring suspended load holding, you must incorporate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 63 mm bore, 120 mm stroke, PT1/4 port, no magnet, and female M10x1.5 rod thread.
Quick checklist
This 63 mm bore cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa. At 0.7 MPa, push increases to 2182.1 N and pull to 1962.2 N. The theoretical maximum push force is 318 kgf at the 1.0 MPa operating pressure limit.
No, this specific SKU does not include the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify the -S option to enable sensing. Additionally, end damping is provided by fixed NBR bumpers, not an adjustable air cushion.
