The AirTAC AirTAC SDA32X140S 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 SDA32X140S is a double-acting, single-rod compact cylinder engineered with a 32 mm bore and a 140 mm stroke. Because this stroke exceeds the 130 mm standard maximum for this bore size, it is produced as a made-to-order unit. It delivers a robust 402.1 N push force at 0.5 MPa, making it well-suited for mid-range actuation tasks.
The riveted body design significantly reduces axial mounting depth compared to conventional round-body units, saving valuable machine footprint. This specific configuration includes a built-in piston magnet (-S) for direct integration with AirTAC reed or electronic switches. End-of-travel deceleration is handled by a fixed NBR bumper, which is not an adjustable air cushion, so high kinetic energy applications should utilize external shock absorbers.

Pushes cartons between sorting lanes on a logistics conveyor line where the 402.1 N output easily redirects heavy boxed goods.
Moves cutting tool holders into a machining center spindle, utilizing the 140 mm travel to clear the work envelope safely.
Folds corrugated box flaps prior to sealing tape application, taking advantage of the compact body to fit within tight packaging machinery frames.
When sizing this actuator, evaluate your force requirements 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. At 0.5 MPa, the 32 mm bore offers a safe working load of roughly 241 N (about 60% of its rated output) and can vertically lift approximately 20.5 kg with a 2:1 safety margin. Keep in mind that a standard SDA body will drift and cannot hold a load if air pressure drops, as the fixed bumper only decelerates the stroke end rather than locking it; utilize an external rod lock for strict position holding.
To order, confirm the 32 mm bore, 140 mm non-standard stroke, PT1/8 port, and the -S magnet option. The piston rod measures 12 mm in diameter and features a female M6x1.0 thread, with a male M10x1.25 option available. Operating speed ranges from 30-500 mm/s.
Quick checklist
This double-acting cylinder provides a push force of 402.1 N and a pull force of 345.6 N at 0.5 MPa. At 0.7 MPa, the push increases to 563 N and the pull to 483.8 N. The theoretical maximum push force is 82 kgf at 1.0 MPa.
Yes, but note that 140 mm exceeds the 130 mm standard maximum stroke for a 32 mm bore, making it a non-standard, made-to-order item. Additionally, the fixed NBR bumpers only decelerate the piston near the stroke ends; they do not function as a lock or brake, so the cylinder will drift if air pressure is lost.
