The AirTAC AirTAC SDA63X45S Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 45mm 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 SDA63X45S is a double-acting, single-rod compact cylinder engineered to deliver 1558.6 N of push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, and piston into a highly shortened unit, saving substantial axial mounting depth compared to conventional round-body actuators. The 63 mm bore is paired with a 20 mm piston rod and a PT1/4 port, while the internal bore wall receives a hard-anodized treatment to minimize friction.
This specific model includes the S option, meaning it carries a built-in piston magnet for direct mounting of AirTAC reed or electronic switches along the body grooves. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, so high-energy cycles may require external shock absorbers. The female M10x1.5 rod-end thread provides a robust load coupling, though side loading should be strictly avoided on this compact format.

Drives ejection pins on a 100-ton injection molding press, utilizing the 1558.6 N extend force to reliably strip dense plastic parts from steel cavities.
Actuates a heavy-duty routing gate on a packaging conveyor, where the 20 mm rod and 45 mm stroke shift loaded pallets laterally at high cycle rates.
Secures heavy cast iron blocks onto a CNC machining center fixture, applying constant 0.5 MPa clamping pressure without consuming excessive Z-axis height.
When sizing this actuator, evaluate your force requirements against adjacent bores: stepping down to the SDA50 yields 981.7 N of push at 0.5 MPa, while the larger SDA80 provides 2513.3 N. The SDA63X45S offers a safe working load of roughly 935 N (about 60% of its 1558.6 N output) and can vertically lift approximately 79.4 kg with a 2:1 safety margin. To confirm your ordering essentials, specify the 63 mm bore, 45 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the required S magnet option.
Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centered. The fixed NBR bumper only decelerates the piston near the stroke limits; it does not function as a locking brake. If your application must hold a suspended load without live pressure, integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
At 0.5 MPa, this 63 mm bore cylinder generates 1558.6 N of push force and 1401.5 N of pull force. At 0.7 MPa, push increases to 2182.1 N. The theoretical maximum push is 318 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
No, the piston will drift if air pressure is lost or the valve is centered. The fixed NBR bumper only decelerates the rod near the stroke endpoints and does not act as a brake. To maintain vertical position holding, you must add an external rod lock or a pilot-operated check valve.
