The AirTAC AirTAC SDA32X25S Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 25mm 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 SDA32X25S is a double-acting, single-rod compact cylinder engineered to deliver a push force of 402.1 N and a pull force of 345.6 N at 0.5 MPa. Its short, riveted body assembly integrates the barrel, rear cover, piston, and rod to drastically reduce axial mounting depth, saving valuable machine footprint where a conventional round-body unit would not fit. The 32mm bore features a hard-anodized inner wall and a two-way piston seal for reliable low-friction operation.
This specific configuration includes a built-in piston magnet (denoted by the S option) enabling position detection via AirTAC reed or electronic switches mounted in the body grooves. The 12mm piston rod utilizes a female M6x1.0 thread, while the PT1/8 port ensures adequate airflow for a speed range of 30-500 mm/s. End-stops rely on a fixed NBR bumper to decelerate the piston, which is not a field-adjustable air cushion.

Secures printed circuit board panels during routing operations where the 402.1 N push force easily overcomes spindle vibration and the short body fits within tight electronics manufacturing cells.
Actuates side flaps on corrugated packaging lines at speeds up to 500 mm/s, with the integrated magnet triggering electronic switches to verify flap position before sealing.
Pushes small stamped metal components out of progressive dies, utilizing the 12mm rod and female M6x1.0 thread to mount custom ejector pins without exceeding the 25mm stroke limit.
When sizing this model, evaluate your force requirements in both directions: stepping down to the SDA25 yields 245.4 N of push force at 0.5 MPa, while stepping up to the SDA40 provides 628.3 N. For the SDA32X25S, the 402.1 N push force at 0.5 MPa translates to a safe working load of roughly 241 N (about 60% capacity) or a vertical lift capability of approximately 20.5 kg with a 2:1 safety margin. Confirm your ordering essentials: 32mm bore, 25mm stroke, PT1/8 port, female M6x1.0 rod thread, and the integrated magnet.
Keep in mind that a standard compact cylinder does not hold its position if air pressure is lost 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 static load holding without live pressure, you must incorporate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
At 0.5 MPa, this double-acting cylinder provides 402.1 N of push force and 345.6 N of pull force. At 0.7 MPa, the push increases to 563 N. The theoretical maximum push is 82 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and it operates effectively between -20 and +70 C.
No, the SDA32X25S uses a fixed NBR bumper at each end to decelerate the piston. It is not an adjustable air cushion. For high-speed or high-energy cycles, you should slow the approach speed or install an external shock absorber. Additionally, the -S option indicates a built-in magnet for use with AirTAC reed or electronic switches.
