The AirTAC AirTAC SDA32X50S Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 50mm stroke, PT1/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA32X50S is a double-acting single-rod compact cylinder engineered to deliver 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod to minimize axial mounting depth, saving valuable machine footprint where a conventional round-body unit would not fit. The 32 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable friction-free operation.
This specific configuration includes a 50 mm stroke and a built-in piston magnet (the S option) for non-contact position sensing. Grooves around the body accept AirTAC magnetic reed or electronic switches to confirm end-of-travel. Instead of an adjustable air cushion, the unit relies on a fixed NBR bumper at each end to absorb shock. The 12 mm piston rod uses an M6x1.0 female thread, and the PT1/8 port ensures adequate airflow for speeds between 30 and 500 mm/s.

Secures aluminum engine blocks onto a CNC machining center, utilizing the 402.1 N extend force to lock parts firmly against locators during high-speed milling.
Drives mechanical arms to fold corrugated box flaps on a continuous packaging line, where the 50 mm stroke and integrated magnet verify flap closure via reed or electronic switches.
Actuates a routing diverter on a parcel logistics conveyor, rapidly pushing packages into secondary chutes with a compact riveted body that fits within tight transfer gaps.
Selecting this 32 mm bore provides a safe working load of roughly 241 N (about 60% of the 402.1 N push figure at 0.5 MPa) and a vertical lift capacity near 20.5 kg with a 2:1 safety margin. If your application requires less force, the smaller SDA25 offers 245.4 N of push at 0.5 MPa. Conversely, stepping up to the SDA40 yields 628.3 N at the same pressure for heavier payloads. Keep in mind that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end rather than locking the rod. To hold a vertical load securely without live pressure, integrate an external rod lock or a pilot-operated check valve. When ordering, confirm the 32 mm bore, 50 mm stroke, PT1/8 port, female rod thread, and the S magnet option.
Quick checklist
This double-acting 32 mm bore cylinder generates 402.1 N push and 345.6 N pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum push force is 82 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
The SDA32X50S includes the S option, meaning it has a built-in piston magnet designed for AirTAC reed or electronic switches. It does not use an adjustable air cushion; instead, a fixed NBR bumper at each end absorbs the end-stop impact. For high-speed or high-energy cycles, you should slow the approach speed or add an external shock absorber.
