About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-50
The AirTAC SDAJ40X75-50 is a compact double-acting cylinder featuring a 50mm adjustable extend window, allowing you to dial the forward stop precisely between 25 and 75mm directly at the machine. Its short riveted body saves valuable axial mounting depth where larger profile cylinders cannot fit. A fixed NBR bumper decelerates the piston near the end of travel, but this is not an adjustable air cushion.
Turning the external M12x1.25 adjuster screw simply moves the mechanical stop; it does not alter the piston area, meaning force remains identical to a standard SDA of this bore. The PT1/8 port and 16mm rod are fixed by the 40mm bore, and this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches.

The adjustment screw shortens the extend stroke by up to 50 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 SDAJ40X75-50 Is Used
Tooling Changeover
Dial the extend stop from 25 to 75mm via the M12 screw during fixture swaps, achieving exact tooling depth without machining new spacers.
Carton Flap Folding
Fine-tune the rod extension between 25mm and 75mm on the packaging line to accommodate varying box heights during rapid format changes.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-50 the Right Cylinder?
Confirm the 40mm bore, 75mm max stroke, 50mm window, PT1/8 port, and female rod thread suit your mounting. Because this SKU has no -S magnet, position sensing is unavailable here. Remember that a plain cylinder does not hold a load on air loss or valve centering—the fixed bumper only decelerates near the end. For secure 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 25–75 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 SDAJ40X75-50 FAQ
Turning the external M12x1.25 screw mechanically shortens the extend stop, letting you set the forward position anywhere between 25mm and 75mm. It acts purely as a stop and does not alter the cylinder's force or lock the piston mid-stroke.
