About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X35-30B
The AirTAC SDAJ40X35-30B is a compact double-acting double-rod cylinder featuring an external M12x1.25 adjustment screw that lets you dial the extend end-position anywhere between 5 and 35 mm directly on your machine. This specific SKU uses a male M14x1.5 piston rod thread for direct mounting.
The short riveted body drastically saves axial mounting depth where a round-body or profile cylinder will not fit. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note that this configuration ships without a piston magnet, so it cannot host reed or electronic switches.

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 SDAJ40X35-30B Is Used
Trial Positioning Jigs
Dial in the exact clamping depth for prototype machining fixtures using the M12x1.25 adjuster, ensuring the male M14x1.5 rod contacts the part precisely before final locking.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X35-30B the Right Cylinder?
Choose this male-rod (M14x1.5) variant when your tooling requires a threaded attachment point.
Operators who frequently changeover product formats or need trial positioning will benefit from the 5-35 mm on-site adjustability without swapping shims or parts. Confirm your setup requires a PT1/8 air port and no position sensing (this SKU lacks the -S magnet). Remember that a plain cylinder does not hold its load on air loss or when the valve is centered; 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.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–35 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 SDAJ40X35-30B FAQ
The theoretical maximum push force is 128 kgf at 1.0 MPa.
Turning the external R (M12x1.25) screw mechanically shortens the extend stroke by up to 30 mm, giving a usable range of 5-35 mm. It only sets the end stop and does not function as a mid-stroke lock; the cylinder cannot hold a load if air pressure is lost.
