About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X40-40
The AirTAC SDAJ40X40-40 is a double-acting compact cylinder featuring an external adjustable extend stop. An M12x1.25 screw lets you dial the forward end-position from 0 to 40 mm directly on your equipment, eliminating the need for shims or part swaps during changeovers.
Built with a short riveted body, this unit saves axial mounting depth where round-body or profile cylinders cannot fit. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches; adding an -S variant enables sensing.

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 SDAJ40X40-40 Is Used
Tooling Changeover
Dial the extend stop from 0 to 40 mm during fixture swaps to accommodate varying part heights without machining new spacers.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X40-40 the Right Cylinder?
Stepping down to an SDAJ32 yields 402.1 N, whereas stepping up to an SDAJ50 provides 981.7 N.
Choose this model if your fixture requires on-site stroke tuning across a 0-40 mm forward window. Confirm your setup needs a PT1/8 air port, a female M8x1.25 rod-end thread, and a 16 mm piston rod. Remember that a plain cylinder drifts when air is lost or the valve is centered; the fixed bumper only decelerates near the end and the adjuster acts as 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 0–40 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 SDAJ40X40-40 FAQ
Turning the M12x1.25 screw shortens the extend stroke by up to 40 mm, setting the stop without altering force. This SKU has no magnet, so it cannot take switches; choosing the -S option adds a magnet for reed or electronic sensing.
