About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X35-40
The AirTAC SDAJ40X35-40 is a compact double-acting double-rod cylinder featuring an external M12x1.25 adjuster screw that dials the extend stop from 0 to 35 mm directly on your machine. The short riveted body drastically reduces axial mounting depth, fitting into tight machinery spaces where longer profile cylinders cannot.
End-of-travel energy is managed solely by a fixed NBR bumper that decelerates the piston near the stop; it is not an adjustable air cushion. This specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches without upgrading to the -S variant. Operating speed spans 30-500 mm/s across a 0.15 to 1.0 MPa pressure range.

The adjustment screw shortens the extend stroke by up to 40 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 SDAJ40X35-40 Is Used
Machining Clamp Tuning
Dial in the exact 0-35 mm extend stop on the fly to clamp raw castings of varying widths without machining custom spacers.
Carton Flap Folding
Adjust the mechanical extend endpoint within seconds during packaging line size changeovers to hit different box depths accurately.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X35-40 the Right Cylinder?
Choose this adjustable model if your fixture changeovers require frequent trial positioning of the extend endpoint without swapping shims.
Confirm your parameters: a 40 mm bore, 35 mm maximum stroke, 40 mm adjustment window, and a PT1/8 air port. This unit has a female M8x1.25 rod-end thread and no magnet. Remember that the fixed NBR bumper and R screw only provide a physical stop; they do not lock the load. If you need to hold position against gravity during air loss or valve centering, you must integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–35 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 SDAJ40X35-40 FAQ
Turning the M12x1.25 R screw shortens the extend endpoint by up to 40 mm, allowing you to set the usable extend stroke anywhere from 0 to 35 mm. The retract stroke remains full, and the screw acts only as a mechanical stop, not a mid-stroke lock.
