About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-40
The AirTAC SDAJ32X65-40 is a compact double-acting single-rod cylinder featuring an external extend stop. A M10x1.25 adjuster screw lets you dial the forward end-position anywhere between 25 and 65 mm directly on the machine, eliminating the need for shims or part swaps. Retract remains at the full length. Because the mechanism only sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, yielding 402.1 N of push at 0.5 MPa.
This 32 mm bore unit saves valuable axial mounting depth thanks to its short riveted body, fitting where larger profile cylinders cannot. It uses a 12 mm piston rod and a PT1/8 port. End-of-travel energy is managed by a fixed NBR bumper that decelerates the piston, though it is not an adjustable air cushion. This specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches; you would need the -S variant for position sensing.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 65 mm |
| Adjustable range | 25 – 65 mm |
| Adjuster thread (R) | M10×1.25 |
| Port size | PT1/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M6×1.0 F / M10×1.25 male (B) |
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Cushion | Fixed NBR bumper (both ends) |
The adjustment screw shortens the extend stroke by up to 40 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
Force matches a standard SDA of the same bore; the adjuster only sets the stop position, not the area. Actual usable force is lower than theoretical due to friction.

Where the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-40 Is Used
Tooling Changeover
Dial the extend stop from 25 to 65 mm during fixture swaps to accommodate varying part heights without machining new spacers.
Flap Sealing
Fine-tune the 402.1 N push stroke on-site to press carton flats securely, adjusting for different box profiles on the fly.
Prototype Positioning
Sweep the extend position during R&D trials to find the exact contact point, leveraging the fixed NBR bumper for repeatable end stops.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-40 the Right Cylinder?
When sizing this unit, consider the neighboring bores to ensure optimal performance. Dropping down to the SDAJ25 provides 245.4 N of push at 0.5 MPa, whereas stepping up to the SDAJ40 yields 628.3 N. The SDAJ32 strikes a middle ground, offering a safe working load of roughly 241 N (about 60% of its 402.1 N capacity) and a vertical lift capability of approximately 20.5 kg with a 2:1 safety margin. Choose this 32 mm model when your application demands precise on-site stroke tuning within the 25-65 mm window.
Verify your requirements against the following specifications: 32 mm bore, 65 mm maximum stroke, 40 mm adjustment window, PT1/8 port, and a female M6x1.0 rod-end thread. Note that a plain SDAJ does not hold a load if air pressure drops or the valve is centered; the piston will drift. For load holding without live pressure, integrate an external rod lock or a pilot-operated check valve. This SKU ships without a magnet.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 25–65 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 M10×1.25 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 SDAJ32X65-40 FAQ
This 32 mm bore cylinder delivers 402.1 N push and 345.6 N pull at 0.5 MPa. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa.
Turning the R (M10x1.25) screw mechanically shortens the extend stroke by up to 40 mm, allowing you to set the forward stop anywhere between 25 and 65 mm. It does not alter the output force, and it is not a mid-stroke lock.
