Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X55-40B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X55-40B is a genuine double-acting COMPACT cylinder (Ø32mm bore) whose extend end-position is set by an external M10×1.25 adjustment screw. You can dial the stroke anywhere from 15 to 55 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X55-40B
The AirTAC SDAJ32X55-40B is a compact double-acting single-rod cylinder built for on-site extend positioning. Its external R (M10x1.25) adjuster screw lets you dial the forward stop anywhere between 15 and 55 mm, eliminating the need for shims or part swaps during changeovers. Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard 32 mm bore SDA, delivering 402.1 N of push at 0.5 MPa.
This variant features a male M10x1.25 piston rod thread and a PT1/8 air port. The short riveted body saves valuable axial mounting depth where larger profile cylinders cannot fit. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches.

| Model | Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X55-40B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 55 mm |
| Adjustable range | 15 – 55 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 SDAJ32X55-40B Is Used
Format Changeover Jigs
Dial in the 15 to 55 mm extend stop on the fly to accommodate different part lengths without fabricating new spacer blocks.
Carton Flap Folding
Use the 402.1 N push force to tuck flaps securely, fine-tuning the M10x1.25 male rod contact point for varying box heights.
Press Fit Alignment
Gradually approach a 20.5 kg vertical lift target by adjusting the stroke window during initial commissioning to prevent component damage.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X55-40B the Right Cylinder?
When sizing this unit, look at both neighboring bores. Stepping down to an SDAJ25 yields 245.4 N of push at 0.5 MPa, while stepping up to an SDAJ40 provides 628.3 N. The 32 mm bore 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.
This model is ideal for setups requiring frequent trial positioning or rapid format changes. Confirm the 32 mm bore, 55 mm maximum stroke, 40 mm adjust window, PT1/8 port, male M10x1.25 rod thread, and absence of a magnet match your layout. Remember that a plain cylinder drifts when air is lost or the valve centers; the bumper and mechanical stop do not lock the load. For vertical holding without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 15–55 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 SDAJ32X55-40B FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402.1 N of push and 345.6 N of pull. 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 shortens the extend stroke by up to 40 mm, giving a usable range of 15 to 55 mm. This SKU has no piston magnet, so it cannot accept reed or electronic switches; you would need the -S option for sensing.
