The AirTAC AirTAC SDA63X90 Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 90mm 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 SDA63X90 is a double-acting single-rod compact cylinder engineered to deliver a push force of 1558.6 N and a pull force of 1401.5 N at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a very short axial package, significantly reducing mounting depth where a conventional round-body unit would not fit. The bore is hard-anodized and uses a two-way piston seal for reliable operation.
This specific configuration features a 90 mm stroke, a 20 mm piston rod, and PT1/4 air ports. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorbers. Because this SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Secures heavy cast iron engine blocks onto machining centers using 1558.6 N of extend force, while the compact riveted body minimizes interference with cutting tool paths.
Actuates a 90 mm routing flap on a packaging conveyor line, handling an estimated 79.4 kg vertical load with a 2:1 safety margin during transit transitions.
Applies downward hold pressure on folded cardboard cartons prior to tape sealing, relying on the fixed NBR bumper to absorb the kinetic energy at the stroke end.
When sizing this unit, evaluate stepping down to the SDA50 which provides 981.7 N of push force at 0.5 MPa, or moving up to the SDA80 which yields 2513.3 N at the same pressure. A practical safe working load for this 63 mm bore is approximately 935 N, or a vertical lift of about 79.4 kg with a 2:1 safety margin. To finalize your order, confirm the 63 mm bore, 90 mm stroke, PT1/4 porting, female M10x1.5 rod thread, and the absence of a sensor magnet.
Note that a standard double-acting cylinder does not hold its position if air pressure is lost or the directional valve is centered. The internal NBR bumper only slows the piston near stroke end and acts purely as a deceleration buffer, never as a locking brake. If your application demands fail-safe load holding, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
At 0.5 MPa this cylinder provides 1558.6 N of push force and 1401.5 N of pull force. At 0.7 MPa the push increases to 2182.1 N. The theoretical maximum push capacity 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 the speed range is 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot host AirTAC reed or electronic switches. You would need the SDA63X90S variant for position sensing. Additionally, the fixed NBR bumper decelerates the piston at the end of travel but is not an adjustable air cushion, so external shock absorbers are recommended for high-speed operations.
