About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X30-30B
The AirTAC SDAJ40X30-30B is a compact double-acting double-rod cylinder featuring an external M12x1.25 adjustment screw that dials the extend stop from 0 to 30 mm directly on your machine. The male M14x1.5 piston rod thread provides a robust mounting interface for your tooling.
Its short riveted body drastically reduces axial mounting depth where a larger profile cylinder will not fit. End-of-travel energy is managed solely by a fixed NBR bumper that decelerates the stroke end; it is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches.

The adjustment screw shortens the extend stroke by up to 30 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 SDAJ40X30-30B Is Used
Tooling Changeover
Dial the extend stop from 0 to 30 mm on the fly to accommodate different part heights during machine setup, avoiding part changes.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X30-30B the Right Cylinder?
Choose this model if your fixture requires frequent on-site stroke tuning to dial in exact end positions without swapping shims.
Confirm your parameters: 40 mm bore, 30 mm stroke, 30 mm adjust window, PT1/8 port, and the male M14x1.5 rod thread. 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, and the screw is a mechanical stop, not a lock. 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 0–30 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 SDAJ40X30-30B FAQ
The theoretical maximum push is 128 kgf at 1.0 MPa.
The M12x1.25 screw shortens the extend stop by up to 30 mm, giving a usable extend range of 0 to 30 mm without changing force. The -B code means it uses a male M14x1.5 piston rod thread. This SKU has no magnet, so it cannot take a switch.
