About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X85-75B
The AirTAC SDAJ40X85-75B is a double-acting compact cylinder featuring an external R (M12x1.25) adjustment screw that dials the extend end-position between 10 and 85 mm directly on your machine.
This variant features a male M14x1.5 piston rod thread and a PT1/8 air port. The short riveted body saves valuable axial mounting depth where a round-body or profile cylinder cannot fit. End-of-travel deceleration is handled by a fixed NBR bumper, which is not an adjustable air cushion.

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 SDAJ40X85-75B Is Used
Machining Clamp Tuning
Dial the extend stop from 10 to 85 mm to secure varied fixture widths on a single machining station without fabricating custom spacers.
Carton Flap Folding
Adjust the male M14x1.5 rod extension on the fly to match different box heights, ensuring precise folding force during rapid packaging changeovers.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X85-75B the Right Cylinder?
Operators needing frequent changeover or trial positioning will benefit from the 75 mm on-site tuning window. Note that a plain cylinder does not hold its load on air loss or when a valve is centred; the piston drifts and the bumper only decelerates near the stroke end. For secure load holding without live pressure, install an external rod lock or a pilot-operated check valve. Confirm your bore, 85 mm max stroke, 75 mm window, PT1/8 port, male M14x1.5 rod, and absence of a magnet before ordering.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–85 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 SDAJ40X85-75B FAQ
The theoretical maximum push is 128 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa at speeds of 30-500 mm/s.
The R (M12x1.25) screw shortens the extend stroke by up to 75 mm, yielding a usable 10-85 mm range. It acts purely as a mechanical stop and does not alter force. The cylinder cannot hold a load on air loss; use an external rod lock or pilot-operated check valve for load holding.
