Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X80-10B
The AirTAC SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X80-10B 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 70 to 80 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X80-10B
The AirTAC SDAJ40X80-10B is a compact double-acting double-rod cylinder featuring an external extend stop. An M12x1.25 adjuster screw lets you dial the outward stroke down by 10 mm directly at the machine, yielding a usable extend range of 70 to 80 mm without swapping shims or parts.
This variant uses a male M14x1.5 piston rod thread and carries no piston magnet. The short riveted body saves axial mounting depth where round-body or profile cylinders will not fit. End shock is handled by a fixed NBR bumper that decelerates the stroke end; it is not an adjustable air cushion or a mid-stroke lock.

The adjustment screw shortens the extend stroke by up to 10 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 SDAJ40X80-10B Is Used
Package Divert Stroke
Adjust the outward reach from 70 to 80 mm on-site to accommodate varying carton widths on a transfer line without changing hardware.
Compact Press Assembly
Fit the short riveted body into a tight fixture to press bearings with a safe 377 N working load, using the male M14x1.5 rod for secure mounting.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X80-10B the Right Cylinder?
Choose this unit when your setup requires on-site stroke tuning between 70 and 80 mm.
Confirm the 10 mm adjust window, PT1/8 air port, and the male M14x1.5 rod thread suit your tooling. Note that a plain cylinder does not hold its load on air loss or valve centering—the piston drifts and the fixed bumper only decelerates near the end. For load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 70–80 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 SDAJ40X80-10B FAQ
Operating pressure is 0.15-1.0 MPa, proof pressure is 1.5 MPa, and speed ranges 30-500 mm/s.
Turning the R (M12x1.25) screw mechanically shortens the extend stop by up to 10 mm, giving a usable 70-80 mm outward range; it does not alter force. This SKU lacks a piston magnet, so it cannot take reed or electronic switches. The screw is a stop, not a lock—the cylinder cannot hold a load on air loss without an external rod lock.
