The AirTAC AirTAC SDA32X65 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 SDA32X65 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 an ultra-short unit, drastically reducing axial footprint compared to conventional round-body designs. This specific configuration features a 32 mm bore, a 65 mm stroke, and a hard-anodized inner wall paired with a two-way piston seal for prolonged service life.
This model uses a 12 mm piston rod and PT1/8 air ports. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycles. Note that this SKU is supplied without a piston magnet, so it cannot host AirTAC reed or electronic switches for position sensing.

Deploys a 65 mm stroke to push singulated printed circuit boards out of a routing fixture, utilizing the 402.1 N extend force to overcome friction without stressing the delicate substrate.
Drives a mechanical arm to tuck minor flaps on packaging lines, where the compact riveted body minimizes interference in tight conveyor overhead spaces.
Maintains precise yarn tension by applying a steady 345.6 N retract force at 0.5 MPa, with the fixed NBR bumpers absorbing the rapid end-of-stroke impacts inherent to loom operation.
When sizing this actuator, evaluate your force margins carefully. 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. The 32 mm bore offers a computed safe working load of roughly 241 N (about 60% of the 402.1 N capacity) and can vertically lift approximately 20.5 kg with a 2:1 safety margin. Ensure your ordering essentials match the application: 32 mm bore, 65 mm stroke, PT1/8 port, female rod thread (M6x1.0), and no sensor magnet.
Keep in mind that a standard double-acting cylinder does not hold its position if air pressure drops or the valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the stroke near its end without acting as a mechanical lock. If your application requires strict load holding on air loss, incorporate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
At 0.5 MPa, the push force is 402.1 N and the pull force is 345.6 N. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed of 30-500 mm/s.
No, this specific SKU lacks the built-in piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need the SDA32X65S variant for position sensing. Additionally, it uses a fixed NBR bumper for end-stop deceleration, not an adjustable air cushion.
