Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-30B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-30B 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 35 to 65 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-30B
The AirTAC SDAJ32X65-30B is a compact double-acting single-rod cylinder featuring an external extend stop. A side-mounted M10x1.25 adjuster screw lets you dial the forward stroke anywhere between 35 and 65 mm directly on the machine, eliminating the need for shims or part swaps. Because the mechanism only limits travel, output force remains identical to a standard 32 mm bore SDA, delivering 402.1 N of push at 0.5 MPa.
This variant features a male M10x1.25 piston rod thread and lacks a piston magnet. Its short riveted body significantly reduces axial mounting depth compared to round-body alternatives, fitting into tight machine envelopes. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion or a mid-stroke lock.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 65 mm |
| Adjustable range | 35 – 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 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 SDAJ32X65-30B Is Used
Tooling Changeover
Dial the 35-65 mm extend stop during rapid fixture swaps to accommodate varying part heights without machining new spacers.
Flap Sealing
Fine-tune the 402.1 N push point on the fly to seal different carton depths accurately on a shared packaging line.
Prototype Positioning
Sweep the forward travel window during R&D testing to find the exact contact point before committing to a hard-coded stroke length.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-30B the Right Cylinder?
When sizing this 32 mm bore actuator, evaluate your neighbors: stepping down to an SDAJ25 yields 245.4 N of push at 0.5 MPa, while moving up to an SDAJ40 provides 628.3 N. The SDAJ32X65-30B hits a solid middle ground, offering a safe working load of roughly 241 N (about 60% of its 402.1 N capacity) and a vertical lift capability near 20.5 kg with a 2:1 safety margin. Choose this specific unit if your fixture requires on-site extend tuning between 35 and 65 mm, uses an M10x1.25 male rod end, and operates on a PT1/8 port.
Keep in mind that a standard cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift. The fixed NBR bumper only decelerates the stroke near the end and acts as a mechanical stop, never a brake. For suspended or gravity-loaded applications, you must integrate an external rod lock or a pilot-operated check valve to secure the payload.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 35–65 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 SDAJ32X65-30B FAQ
At 0.5 MPa it provides 402.1 N push and 345.6 N pull. At 0.7 MPa it yields 563 N push and 483.8 N pull. The theoretical maximum output is 82 kgf at 1.0 MPa.
Turning the M10x1.25 R screw mechanically shortens the extend stop from the 65 mm maximum down to 35 mm. It sets the end position without altering the 402.1 N force, and it is not a mid-stroke lock.
