Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X85-75
The AirTAC SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X85-75 is a genuine double-acting COMPACT cylinder (Ø40mm bore) whose extend end-position is set by an external M12×1.25 adjustment screw. You can dial the stroke anywhere from 10 to 85 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X85-75
The AirTAC SDAJ40X85-75 is a double-acting compact cylinder featuring an external extend stop. An M12x1.25 adjuster screw lets you dial the outward endpoint anywhere between 10 and 85 mm directly at the machine, eliminating the need for shims or part swaps during changeovers. Retract travel remains full length.
The short riveted body minimizes axial mounting depth where space is tight. End shock is managed solely by a fixed NBR bumper, which decelerates the stroke but is not an adjustable air cushion.

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 |

| 0.5 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 SDAJ40X85-75 Is Used
Variable-Length Diverters
Adjust the extend endpoint on-site to handle changing package sizes on a packaging line without swapping out the entire cylinder assembly.
Tiered Lifting Stations
Set precise mechanical lift heights up to 85 mm; the fixed NBR bumper reliably decelerates the 16 mm rod at the upper stop during rapid vertical cycles.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X85-75 the Right Cylinder?
This SDAJ40X85-75 configuration is ideal for setups requiring frequent on-site stroke tuning across a wide 75 mm window. It uses a PT1/8 port, a 16 mm rod, and a female M8x1.25 rod-end thread.
Keep in mind that a plain cylinder does not hold a load if air pressure drops or the valve centers; the piston will drift. The fixed bumper only decelerates near the end of travel and the external screw acts as a mechanical stop, neither functioning as a lock. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve. This specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–85 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 SDAJ40X85-75 FAQ
Turning the external R (M12x1.25) screw mechanically shortens the extend stroke by up to 75 mm, allowing usable endpoints between 10 and 85 mm. It sets the stop position only and does not alter the output force or lock the piston mid-stroke.
