The AirTAC AirTAC SDA32X140B 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 SDA32X140B 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. This specific SKU features a 140 mm stroke, which exceeds the 130 mm standard maximum for this 32 mm bore, making it a non-standard, made-to-order configuration. It is built with a male M10x1.25 piston rod thread, providing a robust external coupling point for your load.
The riveted body design drastically reduces axial mounting depth compared to round-body alternatives, saving valuable machine footprint. Instead of an adjustable air cushion, the piston strikes a fixed NBR bumper at each end to decelerate the stroke. Because this unit lacks the -S magnet option, it cannot support magnetic reed or electronic switches. Furthermore, it will not hold a load if air pressure is lost; the bumper only absorbs end-of-stroke impact rather than acting as a mechanical lock.

Uses the 402.1 N extend force to push cartons off a main packaging line onto a secondary spur, where the male M10x1.25 rod threads securely mount a custom deflector plate.
Opens and closes a heavy sliding machine enclosure, benefiting from the short riveted body that saves axial depth in tight cell layouts while managing the 140 mm travel requirement.
Acts as a pneumatic stop gate for incoming pallets on a vertical lift, providing enough resistance to halt a 20 kg load, though an external check valve is needed to prevent downward drift.
When sizing this actuator, stepping down to the SDA25 yields 245.4 N of push force at 0.5 MPa, while stepping up to the SDA40 provides 628.3 N. For the SDA32X140B specifically, the 402.1 N output at 0.5 MPa translates to a safe working load of roughly 241 N (about 60% capacity) or a vertical lift capability of approximately 20.5 kg with a 2:1 safety margin. If your application requires the piston to remain fixed when air is removed or the valve is centered, you must integrate an external rod lock or a pilot-operated check valve, as the piston will drift. To order, confirm the 32 mm bore, 140 mm non-standard stroke, PT1/8 port, male M10x1.25 rod thread, and the absence of a sensor magnet.
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 force is 563 N and the pull force is 483.8 N. The theoretical maximum push force is 82 kgf at the maximum operating pressure of 1.0 MPa.
No, this specific SKU does not include the -S magnet option, so it cannot trigger AirTAC reed or electronic switches. Additionally, because the 140 mm stroke exceeds the 130 mm standard maximum for a 32 mm bore, it is produced as a non-standard, made-to-order item.
