The AirTAC AirTAC SDA63X5N Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 5mm 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 SDA63X5N is a double-acting, single-rod compact cylinder engineered for very short linear motion. It delivers a substantial 1558.6 N push force at 0.5 MPa within a minimal 5 mm stroke envelope. The riveted unibody construction integrates the barrel, rear cover, and piston to drastically reduce axial mounting depth compared to conventional round-body cylinders.
This specific configuration features a 63 mm bore, a 20 mm piston rod, and PT1/4 air ports. It relies on a fixed NBR bumper at each end to decelerate the end stop rather than an adjustable air cushion. Because this SKU lacks the -S option, it has no piston magnet and cannot support position sensing.

Drives dowel pins into heavy machinery chassis using its 1558.6 N extend force, where the 5 mm stroke limits over-travel and prevents workpiece damage.
Executes localized forming and marking operations on steel plates, utilizing the hard-anodized 63 mm bore to withstand repeated high-impact end stops.
Acts as a rugged stopper block in conveyor lines, raising a 79.4 kg payload against a guide rail before downstream robotic handling takes over.
When sizing this actuator, evaluate your force margins carefully. Stepping down to the SDA50 yields 981.7 N of push at 0.5 MPa, while stepping up to the SDA80 provides 2513.3 N. For the SDA63X5N, a 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. To finalize your order, confirm the 63 mm bore, 5 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the absence of a 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 piston will drift, and the fixed bumper only decelerates the load near the stroke end without acting as a mechanical lock. If your application requires strict position holding, incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
This 63 mm bore cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, and 2182.1 N push at 0.7 MPa. The theoretical maximum push force is 318 kgf at 1.0 MPa. It operates at speeds ranging from 30 to 500 mm/s.
No, this specific SKU lacks the -S magnet option, meaning it has no internal piston magnet and cannot trigger AirTAC reed or electronic switches. You would need to specify the -S option to utilize the body's magnetic-switch grooves.
