The AirTAC AirTAC SDA32X120 Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 120mm 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 SDA32X120 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, piston, and rod into a highly shortened unit, drastically reducing axial footprint compared to conventional round-body designs. This specific configuration features a 32 mm bore, a 120 mm stroke, and a 12 mm piston rod.
This model relies on a fixed NBR bumper at each end to decelerate the piston near stroke limits, meaning it is not field-adjustable like an air cushion. Operating speeds span 30-500 mm/s. Because this SKU lacks the -S magnet code, it cannot support magnetic sensing; adding the -S variant would enable reed or electronic switches in the body grooves.

Pushes corrugated cardboard cartons between sorting lanes on a logistics conveyor, utilizing the 120 mm stroke to clear adjacent guide rails without excessive machine depth.
Opens and closes a sliding safety guard on a turning center, where the short riveted body minimizes interference with the machine enclosure.
Extends a pneumatic tamp pad to apply adhesive labels to plastic bottles, using the 402.1 N output to press firmly against curved surfaces.
When sizing this actuator, compare its 402.1 N push at 0.5 MPa against adjacent bores: stepping down to the SDA25 yields 245.4 N, while stepping up to the SDA40 provides 628.3 N. For this 32 mm bore, the safe working load is approximately 241 N (about 60% of the 0.5 MPa figure), allowing a vertical lift of roughly 20.5 kg with a 2:1 safety margin. Keep in mind a plain cylinder drifts when air is lost or the valve is centered—the fixed bumper only decelerates near the end of travel, so an external rod lock or pilot-operated check valve is required to hold a load securely.
To order, confirm the essentials: 32 mm bore, 120 mm stroke, PT1/8 port, female M6x1.0 rod-end thread (default), and no sensor magnet. The 120 mm stroke sits at the top of the standard range for this bore, making it ideal for maximizing reach within a tight mounting envelope.
Quick checklist
This 32 mm bore double-acting cylinder generates 402.1 N push and 345.6 N pull at 0.5 MPa, and 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum push is 82 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You must select the -S option code to enable sensing capabilities in the body grooves.
