The AirTAC AirTAC SDA63X120H 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 SDA63X120H is a double-acting, single-rod compact cylinder engineered for demanding spatial constraints. Its riveted assembly unites the barrel, rear cover, and piston to minimize axial mounting depth, outperforming conventional round-body units in tight machinery footprints. Equipped with a 63mm bore and a 20mm piston rod, it generates 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa.
This specific SKU integrates fluororubber (FKM) seals for enhanced thermal and oil resistance, operating within a -20 to +70 C environment at 0.15-1.0 MPa. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorbers. Because this configuration lacks the -S magnet option, it cannot support magnetic reed or electronic switches.

Drives ejection pins inside cramped mold bases where the shortened body length prevents interference with the press platen, utilizing the 1558.6 N extend force to strip finished plastic parts.
Lifts tiered product layers using the 79.4 kg vertical lift capacity, while the FKM seals withstand heat from adjacent shrink-wrap tunnels during continuous packaging cycles.
Secures heavy cast iron fixtures on machining centers, relying on the 20mm piston rod to resist deflection and the fixed NBR bumpers to absorb the 120mm stroke endpoint impact.
When sizing this actuator, evaluate your force margins carefully. Stepping down to the SDA50 yields 981.7 N of push at 0.5 MPa, while stepping up to the SDA80 provides 2513.3 N. For this 63mm bore, a safe working load is approximately 935 N (about 60% of the 1558.6 N capacity), translating to a vertical lift capability of roughly 79.4 kg with a 2:1 safety margin. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. To sustain a suspended load, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 63mm bore, 120mm stroke, PT1/4 porting, female M10x1.5 rod thread, and the FKM seal specification.
Quick checklist
This 63mm bore double-acting cylinder outputs 1558.6 N push and 1401.5 N pull at 0.5 MPa, increasing to 2182.1 N push and 1962.2 N pull at 0.7 MPa. The theoretical maximum push force is 318 kgf at 1.0 MPa. It operates on filtered air between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and sustains a speed range of 30-500 mm/s.
No, this specific SKU lacks the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. Additionally, it uses a fixed NBR bumper at each end for end-of-stroke deceleration rather than a field-adjustable air cushion; for high-speed cycling, you should slow the approach or mount an external shock absorber.
