Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-10B
The AirTAC SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-10B 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 65 to 75 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-10B
It features a male-threaded piston rod (M14x1.5) and a fixed NBR bumper at each end to decelerate the stroke, operating efficiently between 30-500 mm/s.
Equipped with an external R (M12x1.25) adjuster screw, this unit allows you to dial the extend stop from 65 to 75 mm directly on the machine without changing parts. The adjuster sets the mechanical stop position but does not alter the bore area or function as 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 SDAJ40X75-10B Is Used
Tooling Calibration
Dial in the 65-75 mm extend stop during initial tooling setup to precisely set forming depth without machining custom spacers.
Product Diverting
Adjust the male M14x1.5 rod extension on the fly to accommodate varying package sizes on a packaging line.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-10B the Right Cylinder?
Confirm the 40 mm bore, 75 mm stroke, 10 mm window, PT1/8 port, and male M14x1.5 rod thread for your mounting interface. Note that this SKU lacks a piston magnet, so position sensing is unavailable without the -S variant. Because the fixed bumper only decelerates near the end of travel, utilize an external rod lock or pilot-operated check valve if you need to hold a load during air loss.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 65–75 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 SDAJ40X75-10B 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 10 mm, giving a usable range of 65-75 mm. This specific SKU has no internal magnet, so magnetic switches cannot be used; you would need the -S option for reed or electronic sensing.
