About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X80-75
The AirTAC SDAJ40X80-75 is a compact double-acting double-rod cylinder engineered for on-site stroke modification. An external M12x1.25 adjuster screw lets you dial the extend stop anywhere between 5 and 80 mm, eliminating the need for shims or part swaps during setup.
The short riveted body conserves valuable axial mounting depth in tight machinery where longer profile or round-body units fail to fit. End-of-travel 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 without upgrading to the -S variant.

The adjustment screw shortens the extend stroke by up to 75 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 SDAJ40X80-75 Is Used
Tooling Changeover
Dial the extend stop from 5 to 80 mm via the M12x1.25 screw to accommodate varying jig heights without machining new spacers.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X80-75 the Right Cylinder?
Stepping down to an SDAJ32 yields 402.1 N, while stepping up to an SDAJ50 provides 981.7 N.
This model is tailored for integrators requiring frequent on-site stroke tuning during product changeovers. Remember that a plain cylinder does not hold its load upon air loss or valve centering; the piston drifts and the fixed bumper only decelerates near the end. For secure load holding without live pressure, install an external rod lock or a pilot-operated check valve. Confirm your requirements for bore, stroke, window, PT1/8 port, female rod thread, and no magnet.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–80 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 SDAJ40X80-75 FAQ
The theoretical maximum push is 128 kgf at 1.0 MPa.
Turning the R (M12x1.25) screw shortens the extend endpoint down by up to 75 mm, giving a usable extend range of 5 to 80 mm. The retract stroke remains full. The screw sets the mechanical stop position and does not alter the output force.
