The AirTAC AirTAC SDA50X120S Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 120mm 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 SDA50X120S is a double-acting single-rod compact cylinder engineered to deliver 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. Its riveted body design integrates the barrel, rear cover, piston, and rod into a highly unified assembly, significantly reducing axial mounting depth where a conventional round-body unit would be too bulky. The 50 mm bore features a hard-anodized inner wall and a two-way piston seal for prolonged operational life.
Equipped with a built-in piston magnet (-S), this model is ready to accept AirTAC reed or electronic switches along the peripheral sensor grooves for precise position detection. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, absorbing impact energy reliably within the 30-500 mm/s speed range.

Actuates routing gates on high-speed logistics conveyor lines, utilizing the 120 mm stroke to push parcels smoothly between sorting lanes.
Drives the folding and tamping mechanisms on continuous motion case erectors, where the compact depth prevents interference with adjacent packaging tooling.
Raises and lowers pallet positioning stops at the infeed of stretch wrappers, providing reliable vertical resistance against heavy pallet loads.
When sizing this unit, consider stepping down to the SDA40, which provides 628.3 N of push at 0.5 MPa, or moving up to the SDA63, which yields 1558.6 N at the same pressure. At 981.7 N, this 50 mm bore offers a safe working load of roughly 589 N (about 60 percent capacity) and can vertically lift approximately 50 kg with a 2:1 safety margin. To order, confirm the 50 mm bore, 120 mm stroke, PT1/4 port, built-in magnet, and the female M10x1.5 rod-end thread.
Keep in mind that a standard compact cylinder will not hold a load if air pressure drops or the directional valve is centered; the piston will drift, and the fixed NBR bumper only decelerates the stroke near its end without acting as a mechanical lock. If your application requires suspended load holding, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This 50 mm bore cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa, 1374.4 N push and 1154.5 N pull at 0.7 MPa, with a theoretical maximum push of 200 kgf at 1.0 MPa. The 120 mm stroke is within the 130 mm maximum standard stroke limit for this bore size.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion; for high-energy cycles, you should slow the approach or add external shock absorbers. The included -S magnet works with AirTAC reed or electronic switches fitted into the body grooves for end-position detection.
