The AirTAC AirTAC SDA32X20BH Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 20mm 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 SDA32X20BH is a double-acting single-rod compact cylinder engineered for tight axial spaces. Its riveted assembly keeps the overall length minimal, saving valuable machine footprint where a standard round-body unit would be too deep. At 32mm bore, it provides 402.1 N of push force and 345.6 N of pull force at 0.5 MPa.
This specific configuration includes a male M10x1.25 piston rod end for direct load coupling and fluororubber (FKM) seals for enhanced thermal and oil resistance. End stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-speed approaches may need external shock absorption. Because this SKU lacks the -S magnet, it cannot host position sensing switches.

Secures aluminum housings inside a CNC machining center, utilizing the 402.1 N extend force to grip parts firmly against a locator while resisting coolant exposure via FKM seals.
Deploys the 20mm stroke to tuck corrugated carton flaps prior to tape sealing on a high-speed packaging line, fitting neatly within narrow side-frame clearances.
Pushes singulated printed circuit boards out of a routing fixture, where the short body depth prevents interference with adjacent tooling and the male M10 rod threads directly into the ejection platen.
When sizing this actuator, stepping down to an SDA25 yields 245.4 N push at 0.5 MPa, while stepping up to an SDA40 provides 628.3 N. For the 402.1 N rating at 0.5 MPa, a safe working load is roughly 241 N (about 60 percent capacity), translating to a vertical lift of approximately 20.5 kg with a 2:1 safety margin. Note that a plain compact cylinder drifts when air pressure is lost or the valve centers; the fixed bumper only decelerates near the stroke end rather than locking the rod. To hold a load securely without live pressure, incorporate an external rod lock or pilot-operated check valve. Confirm your ordering essentials: 32mm bore, 20mm stroke, PT1/8 port, male M10x1.25 rod thread, FKM seals, and no sensor magnet.
Quick checklist
This 32mm 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 force is 82 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, handles speeds of 30-500 mm/s, and functions in temperatures from -20 to +70 C.
No, this specific SKU lacks the -S piston magnet, so it cannot accept reed or electronic switches. Additionally, it uses a fixed NBR bumper at each end to decelerate the stroke rather than an adjustable air cushion. For high kinetic energy loads, you should add an external shock absorber or reduce the approach speed.
