Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-30
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-30 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 50 to 80 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-30
The AirTAC SDAJ32X80-30 is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. Turning the R (M10x1.25) screw lets you dial the forward end-position anywhere between 50 and 80 mm directly on the machine, eliminating the need for shims or part swaps during setup. Retract remains full 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.
This thin riveted-body design saves axial mounting depth where round-body or profile cylinders will not fit. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot support reed or electronic sensing without upgrading to the -S variant.

| Model | Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-30 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 80 mm |
| Adjustable range | 50 – 80 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 30 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 SDAJ32X80-30 Is Used
Gauge Positioning
Dial the extend stop between 50 and 80 mm to test multiple gauge contact points on a trial fixture without machining new spacers.
Changeover Stops
Quickly reset the forward stroke for different product lengths on a packaging line, leveraging the 402.1 N push force to move light actuators.
Clamp Depth Tuning
Fine-tune the clamping depth on a machining cell to avoid deforming delicate parts, relying on the fixed NBR bumper to absorb end shock.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-30 the Right Cylinder?
When sizing this 32 mm bore, compare it 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 push at 0.5 MPa. This SDAJ32X80-30 hits a solid middle ground, offering a safe working load around 241 N (roughly 60 percent of its 0.5 MPa rating) and a vertical lift capacity near 20.5 kg with a 2:1 safety margin.
Choose this model if your application requires frequent on-machine stroke tuning between 50 and 80 mm. It features a 12 mm rod, a PT1/8 port, and female M6x1.0 rod-end threads. Remember that a plain cylinder does not hold its load if air pressure drops or the valve is centered; the piston drifts and the fixed bumper only decelerates near the end of travel. For secure 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 50–80 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 SDAJ32X80-30 FAQ
At 0.5 MPa this 32 mm bore cylinder 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 external M10x1.25 adjuster screw shortens the extend stroke by up to 30 mm, allowing you to set the forward stop anywhere between 50 and 80 mm. This screw acts strictly as a mechanical stop and does not alter the cylinder's force or lock the piston mid-stroke.
