About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-10
The AirTAC SDAJ40X75-10 is a compact double-acting double-rod cylinder featuring an external M12x1.25 adjustment screw. Turning this R thread lets you dial the extend stop down by 10 mm, yielding a usable forward range of 65 to 75 mm directly on the machine without swapping parts. Retract remains full length.
The short riveted body saves axial mounting depth where a larger profile cylinder will not fit. End shock is managed solely by a fixed NBR bumper, which decelerates the stroke end but is not an adjustable air cushion.

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 SDAJ40X75-10 Is Used
Tooling Changeover
Dial in the 65-75 mm extend stop during machine setups to accommodate varying jig heights without machining new spacers.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-10 the Right Cylinder?
Choose it when you need on-site stroke tuning for frequent changeovers. Confirm your required 65-75 mm extend window, PT1/8 port, female M8x1.25 rod thread, and absence of a magnet (no -S code).
Remember that a plain SDAJ does not hold position or load when air is lost or the valve is centred. The fixed bumper only decelerates near the end of travel and the R screw is a mechanical stop, not a lock. For load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 65–75 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 SDAJ40X75-10 FAQ
The M12x1.25 R screw mechanically shortens the extend endpoint from 75 mm down to 65 mm. It does not alter force or lock mid-stroke. Because this SKU lacks the -S magnet, it cannot take magnetic switches, and the cylinder cannot hold a load on air loss without an external rod lock.
