The AirTAC AirTAC SDA32X140 Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 140mm 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 SDA32X140 is a double-acting single-rod compact cylinder featuring a 32mm bore and a 140mm stroke. It generates 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. The riveted body assembly significantly reduces axial mounting depth compared to round-body alternatives, saving valuable machine footprint in tight assemblies. Fluid must be filtered air (40 um), operating within 0.15-1.0 MPa and -20 to +70 C.
Because the 140mm stroke exceeds the 130mm maximum standard for this 32mm bore, this unit is a non-standard made-to-order configuration. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. This SKU lacks the -S piston magnet, so it cannot host reed or electronic switches. The Ø12mm piston rod uses a PT1/8 port and a female M6x1.0 rod-end thread.

Pushes a mechanical diverting arm on a packaging conveyor to route cardboard cartons, utilizing the 402.1 N extend force to overcome side friction.
Advances an ejector pin assembly to push singulated printed circuit boards out of a routing fixture at a safe working load of 241 N.
Extends 140mm to align plastic storage totes on a palletizer bed, requiring a pilot-operated check valve to prevent drift if air pressure drops.
When sizing this actuator, evaluate the adjacent bores: the SDA25 yields 245.4 N push while the SDA40 yields 628.3 N push at 0.5 MPa. For the SDA32X140, a safe working load is roughly 241 N (about 60% of the 402.1 N figure), translating to a vertical lift capacity of 20.5 kg with a 2:1 safety margin. Note that a plain compact cylinder drifts when air is lost or a valve centers; the fixed bumper only decelerates near the stroke end and acts as neither a lock nor a brake. To hold a load securely without live pressure, integrate an external rod lock or pilot-operated check valve. Confirm ordering essentials: 32mm bore, 140mm non-standard stroke, PT1/8 port, no magnet, and female M6x1.0 rod thread.
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 the push is 563 N and pull is 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
No. This specific SKU lacks the -S piston magnet, meaning it cannot accept reed or electronic switches. Additionally, end damping is provided by a fixed NBR bumper that decelerates the stroke end; it is not an adjustable air cushion, so you should slow the approach or add an external shock absorber for high-energy loads.
