About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X65-40
The AirTAC SDAJ40X65-40 is a compact double-acting double-rod cylinder featuring an external adjustable extend stop. An M12x1.25 adjuster screw lets you dial the forward end-position anywhere between 25 and 65 mm directly on the machine, eliminating the need for shims or part swaps.
Built with a short riveted body, this unit saves axial mounting depth where a longer cylinder will not fit. End shock is managed by a fixed NBR bumper that decelerates the piston near the stroke limits; it is not an adjustable air cushion. Operating speed ranges from 30-500 mm/s, and the PT1/8 porting matches the 40 mm bore specification.

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 SDAJ40X65-40 Is Used
Machining Clamps
Dial the extend stop between 25 and 65 mm to clamp raw castings of varying widths on a single fixture without machining custom spacers.
Lab Test Positioning
Set precise trial extension depths for sensor calibration rigs, relying on the fixed NBR bumper to decelerate the 16 mm rod at the end of travel.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X65-40 the Right Cylinder?
Choose this specific model if your fixture requires frequent on-machine stroke tuning within the 25-65 mm window.
Confirm the 65 mm maximum stroke, 40 mm adjustment window, PT1/8 port, and 16 mm rod diameter fit your envelope. Note that this SKU lacks a piston magnet (-S), so it cannot accept magnetic switches. Furthermore, a plain cylinder does not hold position on air loss or valve centering; the fixed bumper only decelerates near the end. 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 25–65 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 SDAJ40X65-40 FAQ
Turning the M12x1.25 external screw shortens the extend stroke by up to 40 mm, allowing you to set the forward stop anywhere from 25 to 65 mm. The screw acts as a mechanical stop and does not alter the output force.
