About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X45-40
The AirTAC SDAJ40X45-40 is a compact double-acting double-rod cylinder featuring an external M12x1.25 adjustment screw that lets you dial the extend stop anywhere between 5 and 45 mm directly on the machine. Retract travel always uses the full stroke length.
Its short riveted body drastically saves axial mounting depth where a longer cylinder would fail to fit, and end-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Operating pressure spans 0.15 to 1.0 MPa, with a speed range of 30-500 mm/s. This specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without upgrading to the -S variant.

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 |

| 0.7 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 SDAJ40X45-40 Is Used
Tooling Changeover
Dial the extend stop from 5 to 45 mm during machine setup to accommodate different part heights without fabricating new spacers.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X45-40 the Right Cylinder?
This model is specified with a 40 mm bore, 45 mm maximum stroke, a 40 mm adjustment window, and a PT1/8 port.
Choose this adjustable-stop version if your application requires frequent on-site stroke tuning or changeover without swapping shims. 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. For load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve. This SKU has no magnet (no -S code) and uses a female M8x1.25 rod-end thread.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–45 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 SDAJ40X45-40 FAQ
At 0.7 MPa, push increases to 879.6 N and pull to 738.9 N. The theoretical maximum push is 128 kgf at 1.0 MPa.
Turning the external M12x1.25 screw shortens the extend stroke by up to 40 mm, allowing on-site positioning between 5 and 45 mm. The screw is strictly a mechanical stop and does not alter the force. It does not lock the piston, so the cylinder cannot hold a load if air pressure is lost.
