The AirTAC AirTAC SDA32X35B Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 35mm 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 SDA32X35B 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 mounting depth where a conventional round-body actuator would be too bulky. The hard-anodized bore interior ensures smooth, low-friction operation throughout the 30-500 mm/s speed range.
This specific SKU is configured with a male M10x1.25 piston rod thread for robust mechanical coupling to your load, paired with a PT1/8 port. End-of-stroke energy is managed solely by a fixed NBR bumper, which decelerates the piston near the stroke limits rather than acting as a lock or adjustable air cushion. Because this model lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches in the body grooves.

Secures aluminum workpieces in a CNC machining center, utilizing the 402.1 N push force to hold parts firmly against locators during high-speed milling operations.
Drives the mechanical flap-folding arms on a continuous packaging line, where the short 35 mm stroke rapidly tucks corrugated box panels prior to sealing.
Pushes singulated printed circuit boards out of a depaneling router fixture, using the male M10x1.25 rod end to attach a soft-tipped ejector pin.
Selecting this 32 mm bore actuator places you in a mid-range force class, yielding a safe working load of roughly 241 N (about 60% of the 402.1 N push at 0.5 MPa) and a vertical lift capacity near 20.5 kg with a 2:1 safety margin. If your application requires less force, the smaller SDA25 provides 245.4 N at 0.5 MPa; if you need more power, stepping up to the SDA40 offers 628.3 N. Keep in mind that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered, so an external rod lock or pilot-operated check valve is necessary to hold a suspended load safely.
When ordering, confirm the essential configuration for this unit: a 32 mm bore, 35 mm stroke, PT1/8 port, male M10x1.25 rod thread (B option), and no sensor magnet. The 35 mm stroke is well within the 130 mm maximum standard stroke for this bore size, but for longer travel distances a guided cylinder is recommended to prevent side-load damage.
Quick checklist
This double-acting 32 mm bore 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. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
No, this cylinder uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion; for high-energy cycles you should slow the approach or add an external shock absorber. Additionally, this specific SKU lacks the -S piston magnet, meaning it cannot support AirTAC reed or electronic switches.
