The AirTAC AirTAC SDA32X65SB Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 65mm 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 SDA32X65SB 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 minimizes axial mounting depth, providing a distinct footprint advantage in tight machinery compared to conventional round-body units. The hard-anodized 32 mm bore operates efficiently between 30 and 500 mm/s.
This specific configuration includes a built-in piston magnet for direct mounting of AirTAC reed or electronic switches along the body grooves. It is equipped with a male M10x1.25 threaded piston rod for secure load coupling, and relies on a fixed NBR bumper at each end to decelerate the stroke rather than an adjustable air cushion.

Actuates a routing flap on a logistics sorting line, utilizing the 65 mm stroke and 402.1 N force to redirect parcels weighing up to 20 kg onto secondary chutes.
Secures aluminum engine blocks during machining operations, leveraging the male M10x1.25 rod end for rigid attachment to the custom jaw mechanism.
Drives a mechanical folding arm on an automated case erector, where the short riveted body saves critical axial space within the compact machine frame.
Selecting this 32 mm bore yields a safe working load of roughly 241 N (about 60% of the 402.1 N push at 0.5 MPa), translating to a vertical lift capacity of approximately 20.5 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA25 provides 245.4 N at 0.5 MPa; conversely, the SDA40 upgrades you to 628.3 N at 0.5 MPa. Keep in mind that a standard SDA body will drift and cannot hold a load if air pressure drops or the valve is centered—the fixed bumper only decelerates near stroke end, so an external rod lock or pilot-operated check valve is required for position holding. When ordering, confirm the 65 mm stroke, PT1/8 port, the -S magnet, and the -B male rod thread.
Quick checklist
At 0.5 MPa, this 32 mm bore cylinder provides 402.1 N of push force and 345.6 N of pull force. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum push is 82 kgf at the 1.0 MPa operating pressure limit.
No, the SDA32X65SB uses a fixed NBR bumper at each end to absorb end-stop impact; it is not an adjustable air cushion. Additionally, it does not hold its load if air is lost—the piston will drift. You must add an external shock absorber for high-speed energy dissipation or a rod lock for position holding.
