Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-50B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-50B 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 15 to 65 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-50B
The AirTAC SDAJ32X65-50B is a compact double-acting single-rod cylinder built with a short riveted body to minimize axial mounting depth in tight machinery. It features an external M10x1.25 adjuster screw that lets you dial the extend stop down from the 65mm maximum to 15mm directly on the machine, eliminating the need for shims or part swaps during changeovers. The retract stroke remains full length.
Because the adjuster only sets the mechanical stop position, force remains identical to a standard SDA of this bore, delivering 402.1 N of push at 0.5 MPa. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. This specific SKU includes a male M10x1.25 piston rod thread and lacks a piston magnet, meaning it cannot host reed or electronic switches without the -S option.

| Model | Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-50B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 65 mm |
| Adjustable range | 15 – 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 50 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 SDAJ32X65-50B Is Used
Tooling Changeover
Dial the extend stop from 65mm down to 15mm via the M10x1.25 screw during product changeovers, adapting the 402.1 N push force to varying fixture heights without machining new spacers.
Flap Folding Arms
Fine-tune the mechanical stop on carton folding arms where a fixed NBR bumper absorbs end shock, allowing operators to test different carton depths on the fly.
Press Fit Gauging
Set precise trial positions for light press fits, leveraging the 20.5 kg vertical lift capacity with a 2:1 margin before locking the male M10 rod into its final production spot.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X65-50B the Right Cylinder?
When sizing this 32mm bore, evaluate your force requirements against its neighbors: 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 SDAJ32X65-50B generates 402.1 N at 0.5 MPa, offering a safe working load of roughly 241 N (about 60% of capacity) and a vertical lift capability of approximately 20.5 kg with a 2:1 safety margin.
Choose this model if your application requires frequent on-site stroke tuning between 15 and 65 mm. Confirm your setup needs the male M10x1.25 rod thread, the PT1/8 air port, and the 50mm adjustment window. Remember that a plain SDAJ does not hold position or load when air is lost or the valve is centered; the fixed NBR bumper only decelerates near the end of travel. For 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 15–65 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 SDAJ32X65-50B FAQ
This 32mm bore double-acting cylinder provides 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 shortens the extend stroke by up to 50mm, allowing you to set the end position anywhere between 15mm and 65mm. This SKU lacks the -S magnet, so it cannot accept reed or electronic switches.
