Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-20
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-20 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 45 to 65 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-20
The AirTAC SDAJ32X65-20 is a compact double-acting single-rod cylinder featuring an external extend stop. An M10x1.25 adjuster screw lets you dial the outward travel anywhere between 45 and 65 mm directly on the machine, eliminating the need for shims or part swaps. Because the mechanism only sets the mechanical stop position, the output force remains identical to a standard SDA of this bore, delivering 402.1 N of push at 0.5 MPa.
Its short riveted body drastically saves axial mounting depth where a longer cylinder would not fit. End-of-stroke energy is managed by a fixed NBR bumper that decelerates the piston, 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 SDAJ32X65-20 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 65 mm |
| Adjustable range | 45 – 65 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 20 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 SDAJ32X65-20 Is Used
Tooling Changeover
Dial the extend stop from 45 to 65 mm via the M10x1.25 screw to accommodate varying jig heights without machining new spacers.
Flap Folding Arms
Set the precise 241 N safe working load contact point on carton folders, relying on the fixed NBR bumper to absorb repeated end shocks.
Trial Positioning Stops
Use the 20 mm adjustment window to find the exact push depth for a 20.5 kg vertical lift before locking the mechanical stop for production.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-20 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. This 32 mm bore offers a calculated safe working load of roughly 241 N (about 60 percent of the 402.1 N figure) and can vertically lift approximately 20.5 kg with a 2:1 safety margin. Choose this model if your fixture requires frequent on-site stroke tuning during changeovers.
Confirm your parameters: 32 mm bore, 65 mm max stroke, 20 mm adjust window, and a PT1/8 port. This configuration ships without a magnet and has a female M6x1.0 rod-end thread. Remember that a plain cylinder does not hold its load on air loss or valve centering; the fixed bumper only decelerates near the end of travel. For a locked position 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 45–65 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 SDAJ32X65-20 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.
Turning the external R (M10x1.25) screw shortens the extend end position anywhere from the full 65 mm down to 45 mm. It acts strictly as a mechanical stop and does not alter force or lock mid-stroke. This SKU has no magnet, so sensing is not supported.
