The AirTAC AirTAC SDA32X80S Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 80mm 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 SDA32X80S 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 space-efficient unit, drastically reducing axial footprint compared to conventional round-body designs. The 32 mm bore features a hard-anodized inner wall and operates on a PT1/8 port.
Equipped with a built-in piston magnet (-S), this unit supports AirTAC reed or electronic switches via the body grooves for precise end-position detection. End-stop energy is managed by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-speed 80 mm strokes. The 12 mm piston rod utilizes a female M6x1.0 thread end, and the unit operates reliably across a 30-500 mm/s speed range.

Drives an 80 mm routing stroke on automated PCB depaneling equipment, utilizing the 402.1 N push force to cleanly shear connector tabs without over-stressing the panel.
Actuates a folding arm on a continuous packaging line, relying on the short riveted body to fit within tight conveyor side-frames while cycling at up to 500 mm/s.
Extends a fluid nozzle into test tubes on a rotary carousel, using the built-in magnet to trigger an electronic switch for precise 80 mm dispensing depth control.
When sizing this model, evaluate your force needs in both directions: stepping down to the SDA25 yields 245.4 N of push at 0.5 MPa, while stepping up to the SDA40 provides 628.3 N. For the 402.1 N rating at 0.5 MPa, a safe working load is approximately 241 N (about 60% capacity), which translates to a vertical lift capability of roughly 20.5 kg with a 2:1 safety margin. Ensure your ordering essentials match this configuration: 32 mm bore, 80 mm stroke, PT1/8 port, female rod thread, and the integrated magnet.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates the end of travel rather than locking it. If your application requires absolute position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This 32 mm bore double-acting cylinder provides 402.1 N push and 345.6 N pull at 0.5 MPa, and 563 N push with 483.8 N pull at 0.7 MPa. The theoretical maximum push is 82 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and supports speeds of 30-500 mm/s.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the piston near stroke completion; it is not an adjustable air cushion. For high-energy or high-speed cycles over the 80 mm travel, you should slow the approach speed or install an external shock absorber to prevent premature wear.
