The AirTAC AirTAC SDA63X140B Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 140mm 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 SDA63X140B 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 merges the barrel, rear cover, and piston into a highly shortened unit, saving valuable axial mounting depth in tight machinery layouts. This specific configuration includes a male M18x1.5 piston rod thread for robust mechanical coupling to your load.
Because the 140 mm stroke exceeds the 130 mm maximum standard stroke for this 63 mm bore, this unit is provided as a non-standard, made-to-order item. The bore is hard-anodized and relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion. Operating speeds span 30-500 mm/s across a 0.15-1.0 MPa pressure range.

Drives a 140 mm travel bed to compress test probes against large PCB panels, utilizing the 1558.6 N push force to ensure solid contact across dense connector arrays.
Extends a routing flap on a packaging line, where the short riveted body conserves frame space and the male M18x1.5 rod securely mounts the deflecting blade.
Raises a 75 kg workpiece tray between processing stations; the 63 mm bore handles the mass easily, though an external check valve is needed to prevent drifting on air loss.
When sizing this actuator, step down to the SDA50 which provides 981.7 N of push at 0.5 MPa, or step up to the SDA80 yielding 2513.3 N at the same pressure. For this 63 mm bore, a safe working load is approximately 935 N (about 60% of the 1558.6 N figure), allowing a vertical lift of roughly 79.4 kg with a 2:1 safety margin. To order, confirm the 63 mm bore, 140 mm non-standard stroke, PT1/4 port, and the male M18x1.5 rod thread. Note that this SKU lacks the -S magnet and cannot accept a reed or electronic switch.
Keep in mind that a plain compact cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift. The fixed NBR bumper only decelerates the motion near the stroke end and acts as neither a lock nor a brake. If your application requires vertical load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder generates 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, with a proof pressure of 1.5 MPa.
No. This specific SKU lacks the -S piston magnet, so it cannot accept reed or electronic switches. Additionally, it uses a fixed NBR bumper to decelerate at stroke ends rather than an adjustable air cushion; for high-energy cycles, slow the approach or add an external shock absorber.
