The AirTAC AirTAC SDA32X75S 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 SDA32X75S 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 space-efficient unit, drastically reducing axial mounting depth compared to conventional round-body designs. Driven by filtered air over a 30-500 mm/s speed range, it fits neatly into tight machinery footprints.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber. The 12 mm piston rod features a female M6x1.0 thread, and air connections use a PT1/8 port.

Secures aluminum engine blocks during CNC machining, utilizing the 402.1 N extend force to hold parts rigidly against the spindle torque.
Deploys the 75 mm stroke to tuck corrugated box flaps prior to tape sealing, fitting within the narrow side frame of the packaging conveyor.
Pushes depaneled circuit boards out of a routing station, using the built-in magnet to trigger a solid-state sensor for part confirmation.
Selecting this 32 mm bore provides a substantial step up from the SDA25, which offers 245.4 N of push at 0.5 MPa, while avoiding the larger footprint of the SDA40 at 628.3 N. For your computed handling needs, this model yields a safe working load of roughly 241 N (about 60% of the 0.5 MPa figure) and can vertically lift approximately 20.5 kg with a 2:1 safety margin. If your application demands position holding upon air loss, note that the piston will drift; an external rod lock or pilot-operated check valve is required.
When ordering, confirm the 32 mm bore, 75 mm stroke, PT1/8 porting, and the integrated magnet for switch sensing. Verify whether you need the standard female M6x1.0 rod end or the optional male M10x1.25 thread to properly couple with your load.
Quick checklist
This 32 mm 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, with a proof pressure of 1.5 MPa.
No, it relies on a fixed NBR bumper at each end to decelerate the piston. It is not an adjustable air cushion, so for high-speed or high-energy cycles, you should slow the approach or add an external shock absorber.
