The AirTAC AirTAC SDA32X65S Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 65mm 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 SDA32X65S 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 drastically reduce axial mounting depth, making it highly effective for machinery where a conventional round-body unit would be too long. The 32 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable low-friction operation.
Equipped with a built-in piston magnet (-S), this model is ready to accept AirTAC reed or electronic switches along the body grooves for precise end-of-stroke detection. The 65 mm stroke operates at speeds between 30 and 500 mm/s, utilizing a fixed NBR bumper at each end to decelerate the piston. Because this bumper is rigid and not an adjustable air cushion, high-energy cycles may require slowing the approach or adding external shock absorbers.

Secures aluminum workpieces in a CNC machining center using the 402.1 N extend force, while the 65 mm stroke clears the cutting envelope during tool changes.
Actuates folding mechanisms on a corrugated box erecting line, where the compact riveted body saves axial space within tight transfer gantries.
Pushes parcels onto a secondary routing belt; the integrated magnet triggers electronic switches to confirm divert status at speeds up to 500 mm/s.
Selecting this 32 mm bore provides a theoretical maximum output of 82 kgf at 1.0 MPa, with a safe working load around 241 N (roughly 60% of the 402.1 N push at 0.5 MPa) and a vertical lift capacity of about 20.5 kg using a 2:1 safety margin. If your application requires less force, the smaller SDA25 offers 245.4 N of push at 0.5 MPa; if you need more power, stepping up to the SDA40 yields 628.3 N. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near the stroke end rather than locking the load—consider an external rod lock or pilot-operated check valve if position holding is critical.
When ordering, confirm the 32 mm bore, 65 mm stroke, PT1/8 port thread, and the female M6x1.0 rod-end thread. This configuration includes the -S magnet for position sensing, while the male M10x1.25 rod thread is available if specified differently.
Quick checklist
At 0.5 MPa, this 32 mm bore 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 and the pull to 483.8 N. The theoretical maximum push is 82 kgf at the maximum operating pressure of 1.0 MPa.
No, the piston will drift if air pressure is lost or the directional valve is centered. The fixed NBR bumpers only decelerate the piston near the stroke endpoints and do not function as a locking brake. For vertical loads requiring position holding, you must add an external rod lock or a pilot-operated check valve.
