About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-40S
The AirTAC SDAJ32X50-40S is a compact double-acting double-rod cylinder featuring an external extend stop. An M10x1.25 adjuster screw lets you dial the forward stroke from 10 to 50 mm directly on the machine, eliminating the need for shims or part swaps during changeovers.
This model includes a built-in piston magnet for AirTAC reed or electronic switches, fitting neatly into the body sensor grooves. The short riveted body saves valuable axial mounting depth where larger profile cylinders cannot fit. End-of-travel shock is managed by a fixed NBR bumper, which decelerates the piston rather than acting as an adjustable air cushion.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |

| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
SDAJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod SDA push of the same bore. Actual usable force is lower than theoretical due to friction.

Where the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-40S Is Used
Tooling Changeover
Dial the extend stop from 10 to 50 mm via the M10x1.25 screw to accommodate varied jig heights without machining new spacers.
Variable Flap Folding
Adjust the mechanical stop on-site for different carton depths, relying on the fixed NBR bumper to absorb the end shock reliably.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-40S the Right Cylinder?
Choosing this bore involves sizing against its neighbors.
This model is ideal for operators needing frequent on-site stroke tuning for trial positioning. It features a 50 mm maximum stroke, a 40 mm adjustment window, a PT1/8 port, a female M6x1.0 rod-end thread, and the -S magnet option. Remember that a plain cylinder does not hold position on air loss; for load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–50 mm
- ✓ Force at your working pressure
- ✓ Access to reach the R adjuster
- ✓ Magnet (S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Lock the M10×1.25 adjuster after setting the stroke.
- check Avoid side load on the piston rod.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-40S FAQ
The theoretical maximum push is 82 kgf at 1.0 MPa.
The external M10x1.25 screw shortens the extend stop by up to 40 mm, giving a usable range of 10 to 50 mm. The included -S magnet works with AirTAC reed or electronic switches for position sensing.
