The AirTAC AirTAC SDA32X25SH 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 SDA32X25SH 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. The riveted unibody design drastically reduces axial mounting depth compared to conventional round-body units, making it highly effective for tight machinery footprints. It features a hard-anodized 32 mm bore and a 12 mm piston rod.
This specific configuration includes an -S piston magnet for direct mounting of AirTAC reed or electronic switches along the body grooves, plus an -H fluororubber (FKM) seal variant for enhanced thermal and oil resistance. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or add external shock absorbers for high-energy loads.

Drives a short 25 mm Z-axis plunge on an electronic PCB depaneling router, utilizing the compact body to minimize gantry interference.
Actuates a folding mechanism on a continuous packaging line, where the FKM seals withstand occasional lubrication mist exposure.
Applies a steady 402.1 N push to seat small bearings into housings, with the fixed NBR bumper absorbing the mechanical end-stop.
When sizing this unit, evaluate your neighbors: the SDA25 provides 245.4 N of push at 0.5 MPa for lighter duties, while the SDA40 steps up to 628.3 N for heavier demands. Based on the 402.1 N output at 0.5 MPa, this 32 mm bore yields a safe working load around 241 N (roughly 60% capacity) and can vertically lift approximately 20.5 kg with a 2:1 safety margin. Confirm your ordering essentials: 32 mm bore, 25 mm stroke, PT1/8 port, female M6x1.0 rod thread, plus the S magnet and H FKM seal options. Note that a standard cylinder drifts when air pressure is lost; if your process requires strict position holding on air loss, integrate an external rod lock or pilot-operated check valve.
Quick checklist
This 32 mm bore double-acting 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 is 82 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles a proof pressure of 1.5 MPa, and runs at speeds from 30-500 mm/s.
No, the fixed NBR bumper only decelerates the piston near the stroke end and does not function as a locking brake. If air pressure drops or the valve is centered, the piston will drift. To maintain a vertical load safely, you must install an external rod lock or a pilot-operated check valve.
