The AirTAC AirTAC SDA32X40BH 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 SDA32X40BH 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 body assembly integrates the barrel, rear cover, and piston into a highly space-efficient package, drastically reducing axial mounting depth compared to conventional round-body units. This specific configuration includes a male M10x1.25 piston rod end for secure mechanical coupling and an FKM (fluororubber) seal variant for enhanced thermal and oil resistance.
The 32 mm bore features a hard-anodized inner wall and operates on a PT1/8 port at speeds between 30 and 500 mm/s. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorption. Because this SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Actuates short-stroke clamping arms on machining centers where the 402.1 N extend force securely holds aluminum housings during milling.
Drives folding mechanisms on packaging lines, utilizing the 345.6 N retract force to tuck corrugated flaps at cycle speeds up to 500 mm/s.
Pivots diverting gates on logistics conveyors, benefiting from the shallow 32 mm bore footprint to fit within tight transfer frame gaps.
When sizing this model, stepping down to the SDA25 provides 245.4 N of push force at 0.5 MPa, while stepping up to the SDA40 yields 628.3 N at the same pressure. For the SDA32X40BH, the computed safe working load is approximately 241 N (about 60% of the 402.1 N figure), translating to a vertical lift capacity of roughly 20.5 kg with a 2:1 safety margin. Be aware that a standard compact cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; maintaining vertical loads requires an external rod lock or a pilot-operated check valve. To order, confirm the 32 mm bore, 40 mm stroke, PT1/8 port, male M10x1.25 rod thread, FKM seals, and the absence of a sensor magnet.
Quick checklist
At 0.5 MPa, the push force is 402.1 N and the pull force is 345.6 N. At 0.7 MPa, the push force is 563 N and the pull force is 483.8 N. The theoretical maximum push force is 82 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa.
This specific SKU lacks the -S magnet option, so it cannot host AirTAC reed or electronic switches. End stops are absorbed by a fixed NBR bumper, which decelerates the piston near the stroke end but is not an adjustable air cushion. For high-speed or high-energy cycles, you should add an external shock absorber.
