Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-40B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-40B 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 40 to 80 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-40B
The AirTAC SDAJ32X80-40B is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. By turning the R (M10x1.25) screw, you can dial the forward end-position anywhere between 40 and 80 mm directly on the machine, eliminating the need for shims or part swaps. Because the adjuster only sets the mechanical stop and not 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 variant features a male M10x1.25 piston rod thread and lacks a piston magnet, meaning it cannot accept magnetic switches without upgrading to the -S option. The short riveted body significantly reduces axial mounting depth compared to round-body alternatives, fitting easily into tight assemblies. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion or a load-holding brake.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 80 mm |
| Adjustable range | 40 – 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 40 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 SDAJ32X80-40B Is Used
Multi-Format Machining Stops
Dial the extend stop between 40 and 80 mm to accommodate different raw material lengths on a single machining fixture without swapping physical stop blocks.
Variable Depth Carton Sealing
Adjust the male M10x1.25 rod extension on the fly to seal cartons of varying heights, using the full 402.1 N of push force to secure the flap.
Trial Positioning for Forming Presses
Fine-tune the forming depth during initial setup by turning the R screw, preventing over-travel on delicate workpieces before locking down the final position.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-40B the Right Cylinder?
When sizing this 32 mm bore actuator, evaluate your force requirements both ways: 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. The SDAJ32X80-40B is ideal for applications needing roughly 241 N of safe working load (about 60% of its 402.1 N capacity) or a vertical lift of 20.5 kg with a 2:1 safety margin. Choose this specific model if your setup requires on-site stroke tuning to accommodate multiple product formats without changing hardware.
Confirm the following specifications match your requirements: 32 mm bore, 80 mm maximum stroke, 40 mm adjustment window, PT1/8 air port, and a male M10x1.25 rod thread. Note that a plain cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift. For load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 40–80 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 SDAJ32X80-40B FAQ
At 0.5 MPa, this double-acting cylinder provides 402.1 N of push force and 345.6 N of pull force. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed of 30-500 mm/s.
The external M10x1.25 adjuster screw mechanically shortens the extend stroke by up to 40 mm, allowing you to set the forward stop anywhere between 40 mm and 80 mm. This SKU does not include a piston magnet, so it cannot accept magnetic switches; you would need the -S variant to use reed or electronic sensors.
