The AirTAC AirTAC SDA63X55 Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 55mm 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 SDA63X55 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. Its riveted assembly unifies the barrel, rear cover, piston, and rod into a highly shortened axial footprint, making it ideal for machinery where a standard round-body unit would protrude too far. The 63 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable pneumatic actuation.
This specific SKU operates without a piston magnet, so it cannot directly host AirTAC reed or electronic switches. End-of-travel deceleration is handled strictly by fixed NBR bumpers rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycling. The 20 mm piston rod terminates in a female M10x1.5 thread, providing a robust connection point for your tooling.

Drives ejection pins on a 150-ton injection molding press where the 1558.6 N extend force clears heavy plastic parts, utilizing the short riveted body to fit within tight mold clamp depths.
Pushes loaded pallets onto a secondary packaging line, handling the 79.4 kg vertical lift margin easily while the 55 mm stroke actuates a routing gate without requiring excessive axial space.
Actuates an upper clamping mechanism on a CNC press brake, where the fixed NBR bumpers absorb the end-stop impact and the 20 mm rod resists deflection during heavy metal forming.
When sizing this model, consider stepping down to the SDA50, which provides 981.7 N of push at 0.5 MPa, or moving up to the SDA80, which yields 2513.3 N at the same pressure. For the SDA63X55, a safe working load is approximately 935 N (about 60% of the 0.5 MPa output), translating to a vertical lift capacity 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 slows the piston near stroke end and does not function as a locking brake. If your application requires position holding on air loss, integrate an external rod lock or a pilot-operated check valve.
To order, confirm the 63 mm bore, 55 mm stroke, PT1/4 port, and the female M10x1.5 rod thread. This base configuration lacks the -S magnet option, so position sensing is not supported without changing the SKU.
Quick checklist
At 0.5 MPa, the push force is 1558.6 N and the pull force is 1401.5 N. At 0.7 MPa, push is 2182.1 N and pull is 1962.2 N. The theoretical maximum push is 318 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa and a speed range of 30-500 mm/s.
No, this specific SKU does not include the -S piston magnet, so it cannot host AirTAC reed or electronic switches. You would need to select the SDA63X55S variant to enable magnetic position sensing. Additionally, end-stop deceleration relies on fixed NBR bumpers, not an adjustable air cushion.
