Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X75-40S
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X75-40S 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 35 to 75 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X75-40S
The AirTAC SDAJ32X75-40S is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. Turning the R (M10x1.25) screw lets you dial the extend position anywhere between 35 and 75 mm directly on your machine, eliminating the need for shims or part swaps during changeovers. Retract remains at the full stroke length.
Because the adjuster only sets the mechanical stop and not the piston area, output force equals a standard SDA of this bore, delivering 402.1 N push at 0.5 MPa. The short riveted body saves valuable axial mounting depth where round-body or profile cylinders will not fit. This unit includes a built-in piston magnet (-S) for AirTAC reed or electronic switches, while a fixed NBR bumper decelerates the stroke end.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 75 mm |
| Adjustable range | 35 – 75 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 SDAJ32X75-40S Is Used
Tooling Changeover
Dial the extend stop from 35 to 75 mm via the M10 screw to accommodate varying jig heights on machining lines without swapping cylinders.
Carton Flap Folding
Fine-tune the 402.1 N push stroke on-site to perfectly fold different box sizes, ensuring crisp creases without crushing the corrugated board.
Prototype Positioning
Use the magnetic piston with electronic switches to test multiple extend endpoints during R&D cycles, safely moving the 20.5 kg vertical load limit.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X75-40S the Right Cylinder?
When sizing this 32 mm bore, look both ways: stepping down to an SDAJ25 yields 245.4 N push at 0.5 MPa, while stepping up to an SDAJ40 provides 628.3 N. The SDAJ32X75-40S is ideal for setups requiring frequent on-machine stroke tuning. Based on the 402.1 N push figure, the safe working load is about 241 N (60% capacity), translating to a vertical lift of roughly 20.5 kg with a 2:1 safety margin.
Remember that a plain cylinder does not hold its load if air is lost or the valve is centered; the piston drifts and the bumper only decelerates near the end. For load holding without live pressure, install an external rod lock or pilot-operated check valve. This configuration confirms a 32 mm bore, 75 mm max stroke, 40 mm window, PT1/8 port, -S magnet, and female M6x1.0 rod-end thread.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 35–75 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 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 SDAJ32X75-40S FAQ
At 0.5 MPa it provides 402.1 N push and 345.6 N pull. At 0.7 MPa it provides 563 N push and 483.8 N pull. The theoretical maximum push is 82 kgf at 1.0 MPa.
The M10x1.25 adjuster screw shortens the extend stop by up to 40 mm, giving a usable range of 35-75 mm; it sets the stop position without changing force. The included -S magnet works with AirTAC reed or electronic switches for position sensing.
