The AirTAC AirTAC SDA63X50SN Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 50mm 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 SDA63X50SN is a double-acting, single-rod compact cylinder engineered to deliver a substantial 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, drastically reducing axial footprint compared to conventional round-body designs. This space efficiency is critical when mounting depth is restricted.
Equipped with a built-in piston magnet (-S), the body features integrated grooves for AirTAC reed or electronic switches to track position. The 20 mm rod utilizes a female M10x1.5 thread, and end-stops rely on a fixed NBR bumper rather than an adjustable air cushion. For high-energy cycles, adding an external shock absorber prevents bumper wear.

Drives ejection pins on a 150-ton injection molding press, utilizing the 1558.6 N extend force to reliably strip plastic housings from deep cavities.
Raises and lowers a 75 kg tooling fixture on an automated assembly pallet, staying within the 79.4 kg vertical lift margin at 0.5 MPa.
Folds heavy cardboard side flaps on a high-speed corrugated carton erector, where the short 63 mm riveted body minimizes frame interference.
When sizing this 63 mm bore, evaluate your force margins: 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. At 0.5 MPa, this model offers a safe working load of roughly 935 N (about 60% of capacity) and can vertically lift approximately 79.4 kg with a 2:1 safety margin. To finalize your order, confirm the 50 mm stroke, PT1/4 port, female rod thread, and the required magnetic sensor.
Note that a plain compact cylinder drifts if air pressure drops or the valve is centered, as the fixed bumper only decelerates near the stroke end rather than locking the load. If your application requires strict position holding without live pressure, incorporate 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.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. The built-in magnet allows you to mount AirTAC reed or electronic switches along the body grooves for precise position detection.
