The AirTAC AirTAC SDA32X40SH Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 40mm 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 SDA32X40SH is a double-acting, single-rod compact cylinder engineered with a 32 mm bore and 40 mm stroke. It generates 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. The riveted unibody construction merges the barrel and covers, drastically reducing axial mounting depth compared to conventional round-body actuators. A hard-anodized bore and two-way piston seal ensure durable, low-friction operation.
This specific configuration includes an -S piston magnet for direct mounting of AirTAC reed or electronic switches along the body grooves, plus an -H fluororubber (FKM) seal variant for enhanced thermal and oil resistance. End-stopping relies on a fixed NBR bumper that decelerates the piston near stroke limits; it is not an adjustable air cushion. Operating speed spans 30-500 mm/s, with a PT1/8 port and a 12 mm rod handling the dynamic load.

Deploys 402.1 N of push to eject machined aluminum components from a CNC fixture, utilizing the FKM seals to withstand residual cutting fluid and heat.
Drives a 40 mm stroke to fold corrugated cardboard flaps on a packaging line, where the compact riveted body minimizes interference in tight conveyor clearances.
Moves a testing probe array into position against a printed circuit board, relying on the -S magnet and an electronic switch to confirm the 40 mm extension precisely.
When sizing this 32 mm bore actuator, evaluate your neighbors: stepping down, the SDA25 yields 245.4 N push at 0.5 MPa, while stepping up to the SDA40 provides 628.3 N. For the SDA32X40SH, the 402.1 N output at 0.5 MPa translates to a safe working load of roughly 241 N (about 60% capacity) and a vertical lift capability of approximately 20.5 kg with a 2:1 safety margin. Confirm your ordering essentials: 32 mm bore, 40 mm stroke, PT1/8 port, female M6x1.0 rod thread, plus the S magnet and H FKM seal options.
Remember that a standard compact cylinder drifts when air pressure is lost or the valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end and does not function as a locking brake. If your fixture must hold a load securely without live pressure, integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
At 0.5 MPa, this double-acting 32 mm bore cylinder provides 402.1 N push and 345.6 N pull. 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 proof pressure of 1.5 MPa, and speeds of 30-500 mm/s.
No, the piston will drift if air is lost or the directional valve is centered. The fixed NBR bumper only decelerates the rod near the end of travel; it is not a mechanical lock. To maintain vertical position without live pressure, you must add an external rod lock or a pilot-operated check valve.
