About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X65-30B
The AirTAC SDAJ40X65-30B is a compact double-acting double-rod cylinder featuring an on-site adjustable extend stop. Turning the external M12x1.25 adjuster screw lets you dial the outward stroke down from the 65 mm maximum to a 35 mm minimum without swapping shims or parts.
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 larger profile cylinder will not 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 option.

The adjustment screw shortens the extend stroke by up to 30 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 SDAJ40X65-30B Is Used
Machining Clamp Depth
Dial the extend stop between 35 and 65 mm to accommodate different raw stock thicknesses on a milling fixture without machining new spacer blocks.
Carton Flap Folding
Fine-tune the push rod end position on-site to match varying box heights, ensuring flaps fold cleanly without crushing the container.
Vertical Lift Stops
Set precise upper travel limits for a 32 kg lift mechanism, using the male M14x1.5 thread to secure the tooling while relying on the stop for positioning.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X65-30B the Right Cylinder?
Choose this model if your fixture requires frequent changeovers or trial positioning within the 35-65 mm window.
Confirm the bore, 65 mm max stroke, 30 mm adjustability, PT1/8 port, and male M14x1.5 rod thread suit your tooling. Remember that a plain SDAJ does not hold position if air pressure drops or the valve centers—the piston will drift and the fixed bumper only decelerates near the end of travel. For suspended or vertical loads that must be locked 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 35–65 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 SDAJ40X65-30B FAQ
The theoretical maximum push force is 128 kgf at 1.0 MPa.
The M12x1.25 adjuster screw mechanically shortens the extend stroke by up to 30 mm, allowing you to set the outward stop anywhere from 35 to 65 mm. This SKU has no piston magnet, so it cannot accept reed or electronic switches; you would need the -S variant for position sensing.
