The AirTAC AirTAC SDA63X65 Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 65mm 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 SDA63X65 is a double-acting single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly shortened unit, drastically reducing axial mounting depth where a conventional round-body actuator would be too bulky. The hard-anodized bore and two-way piston seal ensure durable performance across the 30-500 mm/s speed range.
This specific configuration features a 65 mm stroke and a 20 mm piston rod. End-stop energy is managed strictly by a fixed NBR bumper, which decelerates the piston near stroke limits rather than acting as a lock or brake. Note that this SKU lacks a piston magnet, so it cannot host magnetic switches; the -S variant is required for reed or electronic sensing.

Provides robust 1558.6 N push force to eject dense plastic components from molding tools, utilizing the short riveted body to fit within tight press clamping spaces.
Drives heavy pallet routing arms along packaging lines, where the fixed NBR bumper reliably absorbs the kinetic energy of rapid 65 mm routing strokes.
Raises workpieces weighing up to 79.4 kg in vertical lift assemblies, requiring an external pilot-operated check valve to prevent drifting if compressed air supply fails.
When sizing this 63 mm bore actuator, consider stepping down to the SDA50, which provides 981.7 N of push at 0.5 MPa, or moving up to the SDA80 for 2513.3 N if your application demands heavier thrust. For the SDA63X65, 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.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near the stroke end and provides no holding force. If your setup must maintain position under load loss, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 63 mm bore, 65 mm stroke, PT1/4 port, female M10x1.5 rod thread, and no magnet.
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, the push is 2182.1 N. The theoretical maximum push is 318 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU does not include a piston magnet and cannot host reed or electronic switches. You must select the -S option code to enable sensing capabilities alongside the fixed NBR bumper.
