Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X30-10S
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X30-10S 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 20 to 30 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X30-10S
The AirTAC SDAJ40X30-10S is a compact double-acting single-rod cylinder featuring an external extend stop. An M12x1.25 adjustment screw lets you dial the forward end-position anywhere between 20 and 30 mm directly on the machine, avoiding part swaps during changeover. Because the adjuster sets the mechanical stop rather than the piston area, output matches a standard SDA at 628.3 N push at 0.5 MPa.
Its short riveted body drastically cuts axial mounting depth where larger profile or round-body units fail to fit. The bore uses a fixed NBR bumper to decelerate the stroke end, and the included -S piston magnet supports AirTAC reed or electronic solid-state switches for precise end-of-travel sensing.

| Model | Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X30-10S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Max stroke | 30 mm |
| Adjustable range | 20 – 30 mm |
| Adjuster thread (R) | M12×1.25 |
| Port size | PT1/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M8×1.25 F / M14×1.5 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 10 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 SDAJ40X30-10S Is Used
Tooling Changeover
Dial the extend stop from 20 to 30 mm to accommodate different jig heights on a machining line without fabricating new spacers.
Carton Flap Folding
Fine-tune the 628.3 N push stroke on-site to gently fold varying box thicknesses without crushing the corrugated material.
Vertical Lift Stops
Set precise upper travel limits for a 32 kg lift fixture, relying on the mechanical stop rather than relying solely on valve timing.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X30-10S the Right Cylinder?
When sizing this 40 mm bore, compare its 628.3 N push at 0.5 MPa against adjacent bores. Stepping down to an SDAJ32 yields 402.1 N, whereas stepping up to an SDAJ50 provides 981.7 N. For your build, verify the 30 mm maximum stroke, the 10 mm adjustment window, the PT1/8 port, and the built-in magnet. A practical safe working load is roughly 377 N, or lifting about 32 kg vertically with a 2:1 safety margin.
Remember that a plain compact cylinder drifts when air is lost or the valve centers. The fixed bumper only decelerates near the end of travel and the M12 screw acts as a mechanical stop, neither function serves as a brake. To suspend a load safely without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 20–30 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 SDAJ40X30-10S FAQ
This 40 mm bore double-acting cylinder delivers 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum of 128 kgf at 1.0 MPa. Operating speed ranges from 30 to 500 mm/s.
The M12x1.25 screw shortens the extend stroke by up to 10 mm, giving a usable forward range of 20 to 30 mm while retract remains full. The built-in -S magnet works directly with AirTAC reed or electronic switches for position sensing.
