The AirTAC AirTAC SDA32X75SH Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 75mm 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 SDA32X75SH 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 assembly merges the barrel, rear cover, and piston into a highly shortened unit, drastically reducing axial mounting depth compared to conventional round-body actuators. The 12 mm piston rod utilizes a female M6x1.0 thread, and the body features integrated grooves for position sensing.
This specific configuration includes the -S option for a built-in piston magnet, enabling tracking via AirTAC reed or electronic switches. The -H designation indicates the use of fluororubber (FKM) seals, providing enhanced resistance to higher temperatures and oily environments. End-stopping is handled by a fixed NBR bumper that decelerates the piston near stroke completion rather than acting as a lock. Operating speed ranges from 30-500 mm/s through its PT1/8 port.

Secures aluminum workpieces inside CNC machining centers, leveraging the 402.1 N extend force to hold parts firmly against cutting forces while fitting within tight tooling envelopes.
Drives the mechanical arms that tuck minor flaps on automated packaging lines, where the 75 mm stroke provides the precise reach needed without extending the machine footprint.
Pushes tested samples out of high-temperature laboratory inspection chambers, utilizing the FKM seals to maintain integrity in thermally demanding cycling environments.
When sizing this 32 mm bore actuator, evaluate your adjacent options: stepping down to the SDA25 yields 245.4 N of push at 0.5 MPa, while moving up to the SDA40 provides 628.3 N. For this model, a 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. Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure drops 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, 75 mm stroke, PT1/8 port, female rod thread, S magnet, and H FKM seal.
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, push is 563 N and pull is 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion or a locking brake. For high-energy cycles, add an external shock absorber. The built-in magnet works with AirTAC reed or electronic switches mounted in the body grooves.
