About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X80-75B
The AirTAC SDAJ40X80-75B is a compact double-acting cylinder featuring an external R (M12x1.25) adjustment screw that lets you dial the extend stop anywhere between 5 and 80 mm directly on your machine.
This variant uses a male M14x1.5 piston rod thread and a PT1/8 air port. Its short riveted body saves valuable axial mounting depth where a longer cylinder would fail to fit. End-of-stroke deceleration is handled by a fixed NBR bumper, which is not an adjustable air cushion. Note that this SKU lacks a piston magnet, so it cannot support reed or electronic sensing.

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 SDAJ40X80-75B Is Used
Variable Length Stoppering
Dial in the extend position from 5 to 80 mm on the fly for packaging lines running mixed carton lengths without swapping hardware.
Male Rod Tooling Mount
Secure custom grippers or clamps directly to the M14x1.5 male piston rod for precise trial positioning during short-run machine setups.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X80-75B the Right Cylinder?
Choose this male-rod (-B) model when your fixture requires an externally threaded M14x1.5 rod end, and rely on the 75 mm window for frequent format changeovers. Remember that a standard cylinder does not hold a load if air pressure drops or the valve centers; the piston will drift. For suspended or vertical loads, install an external rod lock or a pilot-operated check valve.
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 SDAJ40X80-75B FAQ
This 40 mm bore double-acting cylinder pushes at 628.3 N and pulls at 527.8 N when supplied with 0.5 MPa. 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. Operating pressure spans 0.15 to 1.0 MPa, with a speed range of 30-500 mm/s.
Turning the M12x1.25 R screw shortens the extend stroke by up to 75 mm, yielding a usable range of 5 to 80 mm. The screw functions strictly as a mechanical end stop and does not alter the cylinder's force. It is not a mid-stroke lock; the cylinder cannot hold a load without live air pressure.
