Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-30B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-30B 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 SDAJ32X80-30B
The AirTAC SDAJ32X80-30B is a compact double-acting single-rod cylinder featuring an external M10x1.25 adjustment screw that dials the extend stop anywhere between 50 and 80 mm directly on your machine. Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering 402.1 N of push at 0.5 MPa. This specific SKU uses a male M10x1.25 rod thread and lacks a piston magnet.
Its short riveted body drastically reduces axial mounting depth compared to conventional round-body units, fitting into tight machine envelopes. The bore accepts a PT1/8 air port and relies on a fixed NBR bumper at each end to decelerate the stroke. For vertical lifting tasks, the computed safe working load is approximately 241 N (about 60 percent of the 0.5 MPa push figure), which translates to lifting roughly 20.5 kg with a 2:1 safety margin.

| Model | Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-30B |
|---|---|
| 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 SDAJ32X80-30B Is Used
Tooling Changeover
Dial the extend stop from 50 to 80 mm via the M10x1.25 screw during fixture swaps, avoiding part changes while maintaining 402.1 N of push at 0.5 MPa.
Carton Flap Folding
Fine-tune the male M10x1.25 rod extension on the fly for varying box heights, using the fixed NBR bumper to absorb the end-of-stroke shock.
Trial Positioning
Set precise extend endpoints during machine commissioning, safely moving loads up to 20.5 kg vertically with a 2:1 safety margin.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-30B the Right Cylinder?
When sizing this 32 mm bore, evaluate both neighbours: 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. Choose this 32 mm model when your changeover requires frequent, on-site extend tuning between 50 and 80 mm without swapping shims or parts. Confirm your machine accepts the PT1/8 port, the male M10x1.25 rod end, and the 30 mm adjustment window.
Note that this specific SKU omits the magnet option, so it cannot accept AirTAC reed or electronic switches. Furthermore, a plain compact cylinder does not hold position or load when air is lost or the valve is centred; the fixed NBR bumper only decelerates near the end of travel. For load holding without live pressure, integrate 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 SDAJ32X80-30B FAQ
This 32 mm bore double-acting cylinder delivers 402.1 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum push of 82 kgf at 1.0 MPa.
Turning the external R (M10x1.25) screw mechanically shortens the extend stroke by up to 30 mm, yielding a usable 50-80 mm range. It acts purely as a stop and does not lock the piston; for load holding without live air pressure, you must use an external rod lock or pilot-operated check valve.
