The AirTAC AirTAC SDA32X40SN 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 SDA32X40SN 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 to drastically reduce axial mounting depth, saving valuable machine footprint where a standard round-body unit would never fit. The hard-anodized bore ensures smooth, low-friction travel across the 40 mm stroke.
This specific configuration includes a built-in piston magnet (the S option) for position detection via AirTAC reed or electronic switches mounted in the body grooves. End-of-travel energy is managed by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or add an external shock absorber for high-speed cycling. The 12 mm rod uses a standard female M6x1.0 thread end.

Secures aluminum engine blocks during machining operations, utilizing the 402.1 N extend force to hold parts rigidly against the spindle torque without excessive bulk.
Drives the mechanical arms that tuck corrugated box flaps prior to sealing, where the 40 mm stroke and compact riveted body fit neatly within tight conveyor side frames.
Pushes populated printed circuit boards out of testing trays, relying on the magnetic piston for precise end-position signaling to the PLC.
When sizing this 32 mm bore actuator, compare its 402.1 N push at 0.5 MPa against adjacent bores to find your exact fit. Stepping down, the SDA25 yields 245.4 N; stepping up, the SDA40 provides 628.3 N. For this model, a safe working load is approximately 241 N (about 60% of the 0.5 MPa push figure), translating to a vertical lift capacity of roughly 20.5 kg with a 2:1 safety margin. Keep in mind a standard compact cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates the stroke end, so an external rod lock or pilot-operated check valve is required to hold a load securely.
To order, confirm your essential parameters: 32 mm bore, 40 mm stroke, PT1/8 port, the built-in magnet (S), and female rod thread. An N suffix appears in this code but falls outside standard AirTAC options, so verify any undocumented features with our team before finalizing.
Quick checklist
This double-acting cylinder generates 402.1 N push and 345.6 N pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum push force is 82 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. If your cycle speed is high, add an external shock absorber. Additionally, it will not hold a load if air is lost; use an external rod lock or pilot-operated check valve for fail-safe holding.
