Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X80-30B
The AirTAC SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X80-30B 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 50 to 80 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X80-30B
The AirTAC SDAJ40X80-30B is a compact double-acting double-rod cylinder featuring an on-site adjustable extend stop. A front R (M12x1.25) screw lets you dial the outward travel down from the 80 mm maximum to a 50 mm minimum, eliminating the need for shims or part swaps during machine commissioning.
This thin riveted-body design saves valuable axial mounting depth where larger profile cylinders cannot fit. The bore dictates a 16 mm piston rod with a male M14x1.5 thread end, and end-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note this specific SKU lacks a piston magnet, so it cannot support position sensing.

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 SDAJ40X80-30B Is Used
Tooling Changeover
Dial the extend stop from 50 to 80 mm via the M12x1.25 screw to accommodate varying fixture heights on machining centers without machining new spacers.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X80-30B the Right Cylinder?
This model is ideal for operators needing frequent on-machine stroke tuning between 50 and 80 mm during changeovers.
Confirm your requirements for the 40 mm bore, 80 mm stroke, 30 mm window, PT1/8 port, and the male M14x1.5 rod thread. Keep in mind that a plain cylinder does not hold its load if air pressure drops or the valve is centered—the piston will drift, as the fixed bumper only decelerates near the end of travel and the R screw is a mechanical stop, not a lock. For suspended or vertical loads requiring holding power without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 50–80 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 SDAJ40X80-30B FAQ
The theoretical maximum push is 128 kgf at 1.0 MPa.
The external R (M12x1.25) screw mechanically shortens the extend stroke by up to 30 mm, allowing usable outward travel between 50 and 80 mm without altering force. This specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches; you would need the -S variant for sensing.
