Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X35-40
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X35-40 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 0 to 35 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X35-40
The AirTAC SDAJ32X35-40 is a compact double-acting single-rod cylinder featuring an external R (M10x1.25) adjuster screw. Turning this screw shortens the extend stop on-site, providing a usable extend range of 0-35mm without requiring shims or part changes. Retract remains full length, and the adjuster purely sets the mechanical stop without altering the pneumatic force.
Delivering 402.1 N of push force at 0.5 MPa, this unit matches the output of a standard SDA32 bore. Its short riveted body saves valuable axial mounting depth where round-body or profile cylinders cannot fit. End shock is managed solely by a fixed NBR bumper which decelerates the piston, meaning it is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet and cannot support sensing.

| Adjustable range | 0 – 35 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 SDAJ32X35-40 Is Used
Tooling Changeover
Dial in the 0-35mm extend position during machine changeovers to accommodate different fixture heights without disassembling the pneumatic line.
Transfer Diverter
Set the exact push-off distance for varying package sizes on a conveyor, relying on the 402.1 N push force to clear the belt.
Trial Positioning
Use the external M10x1.25 screw to fine-tune the extend stop during initial prototyping until the optimal mechanical endpoint is found.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X35-40 the Right Cylinder?
When sizing this 32mm bore, consider the neighbouring options. Stepping down, the SDAJ25 provides 245.4 N of push at 0.5 MPa, whereas stepping up, the SDAJ40 yields 628.3 N at 0.5 MPa. This SDAJ32X35-40 generates 402.1 N at 0.5 MPa, translating to a safe working load of roughly 241 N or a vertical lift capacity of about 20.5 kg with a 2:1 safety margin.
This model is ideal for operators needing frequent on-machine stroke tuning during setup or changeovers. Confirm your parameters: 32mm bore, 35mm nominal stroke, 40mm adjust window, PT1/8 port, female M6x1.0 rod thread, and no magnet. A plain cylinder does not hold a load on air loss or valve centering; the bumper only decelerates near the end. For load holding 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 0–35 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 SDAJ32X35-40 FAQ
At 0.5 MPa the push force is 402.1 N and the pull force is 345.6 N. At 0.7 MPa the push is 563 N and pull is 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa.
The R (M10x1.25) screw shortens the extend stop by up to 40mm, yielding a usable extend range of 0-35mm. The screw is a mechanical stop, not a mid-stroke lock, and the cylinder cannot hold a load if air pressure is lost.
