About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-30
The AirTAC SDAJ32X65-30 is a compact double-acting single-rod cylinder featuring an external extend stop. Turning the R (M10x1.25) adjuster screw lets you dial the forward end-position anywhere between 35 and 65 mm directly on the machine, eliminating the need for shims or part swaps. Because the mechanism restricts travel rather than piston area, output remains identical to a standard SDA of this bore, yielding 402.1 N of push at 0.5 MPa.
Its short riveted body minimizes axial mounting depth where larger profile housings will not fit. End-of-travel deceleration is handled by a fixed NBR bumper at each end, which absorbs shock but is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without upgrading to an -S variant.

| Model | Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-30 |
|---|---|
| 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 SDAJ32X65-30 Is Used
Tooling Changeover
Dial the extend stop from 35 to 65 mm during fixture swaps to accommodate varying part heights without machining new spacers.
Flap Sealing
Fine-tune the 402.1 N push stroke on-site to press carton flats securely, adapting to different box profiles on the fly.
Bending Setup
Establish precise trial bend depths by adjusting the M10x1.25 screw, ensuring the 20.5 kg vertical lift capacity meets the workpiece demand.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-30 the Right Cylinder?
When sizing this 32 mm bore, compare its 402.1 N push at 0.5 MPa against adjacent models. Stepping down, the SDAJ25 provides 245.4 N, whereas stepping up to the SDAJ40 yields 628.3 N. A practical safe working load is roughly 241 N (about 60 percent of the 0.5 MPa figure), translating to a vertical lift capacity of approximately 20.5 kg with a 2:1 safety margin. Choose this unit when your fixture requires exact forward positioning tweaked during commissioning. Confirm your parameters: 32 mm bore, 65 mm max stroke, 30 mm window, PT1/8 port, female M6x1.0 rod thread, and no magnet.
Remember that a standard compact cylinder cannot hold a load if air pressure drops or the valve centers. The piston will drift, and the fixed bumper only decelerates near the stroke end without acting as a brake. To suspend a vertical load safely without live pressure, integrate an external rod lock or a pilot-operated check valve into your circuit.
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 SDAJ32X65-30 FAQ
At 0.5 MPa it provides 402.1 N push and 345.6 N pull. At 0.7 MPa it delivers 563 N push and 483.8 N pull. The theoretical maximum is 82 kgf at 1.0 MPa. Operating pressure spans 0.15 to 1.0 MPa, with a speed range of 30-500 mm/s.
The external M10x1.25 screw acts as a mechanical stop that shortens the forward stroke by up to 30 mm, allowing usable extensions between 35 and 65 mm. It sets the end position without altering force, and retract remains full length.
