The AirTAC AirTAC SDA32X40SBH Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 40mm 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 SDA32X40SBH is a double-acting, single-rod compact cylinder engineered for tight axial spaces. A riveted assembly joining the barrel, rear cover, and piston yields a remarkably short overall length, conserving valuable machine footprint where a conventional round-body unit would be too deep. In this 32 mm bore configuration, it generates 402.1 N of push force and 345.6 N of pull force at 0.5 MPa.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. It also features a male-thread piston rod end (-B, M10x1.25) for secure mechanical load coupling, and fluororubber (FKM) seals (-H) for enhanced thermal and oil resistance. End-stopping is handled by a fixed NBR bumper, which decelerates the piston near stroke end but is not an adjustable air cushion.

Secures aluminum engine blocks during machining. The 402.1 N extend force at 0.5 MPa provides rigid holding, while the FKM seals withstand exposure to synthetic cutting fluids.
Drives the mechanical arms that tuck corrugated box flaps prior to sealing. The 40 mm stroke and short riveted body keep the packaging line footprint minimal without sacrificing actuation speed.
Positions delicate printed circuit boards on a conveyor prior to pick-and-place. The male M10x1.25 rod threads securely into the alignment jaw, and the -S magnet enables precise stroke-end detection.
Selecting this 32 mm bore provides a practical middle ground: it steps up notably from the SDA25 (245.4 N push at 0.5 MPa) while remaining more compact than the SDA40 (628.3 N push at 0.5 MPa). Based on the 402.1 N push figure at 0.5 MPa, the computed safe working load is approximately 241 N (operating at a 60% derating), translating to a vertical lift capacity of about 20.5 kg with a 2:1 safety margin. Ensure your ordering essentials cover the 40 mm stroke, PT1/8 port, male M10x1.25 rod, the required magnetic switch capability, and FKM seals.
Keep in mind that a standard compact cylinder does not hold its position if air pressure drops or the control valve is centered; the piston will drift, and the fixed bumper only decelerates the stroke end without acting as a lock. If your application must sustain a load without live pressure, incorporate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This 32 mm bore double-acting cylinder outputs 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 on filtered air at 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and sustains a speed range of 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston near the stroke limits; this is not a field-adjustable air cushion, so high-speed applications may require an external shock absorber. Additionally, the bumper is not a braking device, meaning the piston will drift if air pressure is lost, requiring an external rod lock for fail-safe load holding.
