The AirTAC AirTAC SDA32X15SH Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 15mm 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 SDA32X15SH is a double-acting single-rod compact cylinder engineered for tight machinery footprints. Its riveted body assembly significantly shortens axial mounting depth compared to round-body units, yielding a robust 402.1 N push force at 0.5 MPa across a 15 mm stroke. The bore is hard-anodized, and the unit operates at speeds between 30-500 mm/s.
This configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. It also features fluororubber (FKM) seals (-H) for enhanced thermal and oil resistance. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow high-velocity approaches or add external shock absorbers to mitigate impact energy.

Secures printed circuit boards during routing with a 241 N safe working load, while the FKM seals resist heat from high-speed spindle proximity.
Drives a 15 mm sealing stroke on packaging equipment where the short riveted body minimizes axial length and the built-in magnet tracks jaw position.
Actuates chemical dispensing valves, leveraging the 32 mm bore and fluororubber construction to maintain reliable force in elevated temperature environments.
Selecting this 32 mm bore provides a practical middle ground: it steps up from the SDA25 delivering 245.4 N push, yet remains below the SDA40 rated for 628.3 N push at 0.5 MPa. For your computed loads, this yields a safe working capacity around 241 N (approximately 60% of the 402.1 N figure) and a vertical lift capability near 20.5 kg with a 2:1 safety margin. Ensure you specify the PT1/8 port, the 15 mm stroke, the female M6x1.0 rod thread, and the FKM seal option when ordering.
Keep in mind that a standard double-acting cylinder drifts when air pressure drops or the valve centers. The fixed NBR bumper only decelerates the piston near stroke end and does not function as a locking brake. If your fixture must maintain vertical position without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this 32 mm bore cylinder provides 402.1 N push and 345.6 N pull. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
No, the piston will drift if air pressure is lost or the control valve is centered. The fixed NBR bumper only decelerates the rod near the end of its stroke; it is not a brake. You must add an external rod lock or pilot-operated check valve to hold suspended loads safely.
