About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-75B
The AirTAC SDAJ40X75-75B is a compact double-acting double-rod cylinder featuring an external adjustable extend stop. An M12x1.25 screw lets you dial the outward stroke down by up to 75mm directly at the machine, yielding a usable extend range of 0-75mm without swapping shims or parts.
Its short riveted body drastically cuts axial mounting depth where round-body or profile cylinders cannot fit. This specific SKU includes a male M14x1.5 piston rod thread and lacks a piston magnet, meaning it cannot host reed or electronic switches. End shock is managed solely by a fixed NBR bumper, which decelerates the piston near the end of travel rather than acting as a lock.

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 SDAJ40X75-75B Is Used
Carton Flap Folding
Fine-tune the male M14x1.5 rod extension on the line to accommodate varying box heights, ensuring precise mechanical positioning before the fixed NBR bumper takes the shock.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-75B the Right Cylinder?
Choose this 40mm option when your setup requires on-site stroke tuning to perfect end positions during changeovers.
Verify your requirements for a 40mm bore, 75mm maximum stroke, and a 75mm adjustment window. This variant features a PT1/8 port, a male M14x1.5 rod end, and no magnet. Note that a plain cylinder does not hold a load if air pressure drops or the valve is centred; the piston will drift. For load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–75 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 SDAJ40X75-75B FAQ
The theoretical maximum push is 128kgf at 1.0MPa.
Turning the M12x1.25 adjuster screw shortens the extend end position by up to 75mm, giving a usable extend range of 0-75mm. The screw sets the mechanical stop and does not alter the force. This SKU lacks the -S magnet, so it cannot accept reed or electronic switches.
