About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X65-10B
The AirTAC SDAJ40X65-10B is a compact double-acting double-rod cylinder featuring an external extend stop. An M12x1.25 adjuster screw lets you dial the extend position on the machine between 55 and 65 mm, eliminating the need for shims or part swaps during fine-tuning.
This variant uses a male M14x1.5 piston rod thread and a PT1/8 air port. The short riveted body minimizes axial mounting depth in tight fixtures, while a fixed NBR bumper decelerates the stroke end. Note that this SKU lacks a piston magnet, so magnetic sensing is not supported.

The adjustment screw shortens the extend stroke by up to 10 mm. SDAJ is a double-rod cylinder. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 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 SDAJ40X65-10B Is Used
Press Fit Depth Tuning
Dial the M12x1.25 screw to set the extend stop between 55 and 65 mm, ensuring precise bearing seating without swapping physical spacers.
Carton Flap Folding
Adjust the male M14x1.5 rod end position on the fly to accommodate varying box heights during production changeovers.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X65-10B the Right Cylinder?
When sizing this 40 mm bore, consider the neighboring options. Choose this specific model when your setup requires on-site extend tuning within the 55-65 mm window.
Confirm the 40 mm bore, 65 mm maximum stroke, 10 mm adjustment window, and PT1/8 port match your pneumatic layout. The male M14x1.5 rod end (-B) must suit your mounting interface. A plain cylinder does not hold a load if air pressure drops or the valve centers; the piston drifts, and the fixed NBR bumper only decelerates near the end of travel. For secure load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 55–65 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 M12×1.25 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 SDAJ40X65-10B FAQ
The external M12x1.25 screw shortens the extend stop by up to 10 mm, giving a usable range of 55-65 mm. This SKU has no piston magnet, so it cannot support reed or electronic switches; you would need the -S variant for sensing.
