About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-75
The AirTAC SDAJ32X80-75 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 stroke down from the 80 mm maximum to as low as 5 mm directly on the machine, eliminating the need for shims or part swaps. The adjuster strictly sets the mechanical end position; it does not alter the effective piston area, so 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 significantly reduces axial mounting depth, fitting into tight spaces where bulkier alternatives fail. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, meaning it cannot accommodate reed or electronic switches without upgrading to the -S variant.

| Model | Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-75 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 80 mm |
| Adjustable range | 5 – 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 75 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 SDAJ32X80-75 Is Used
Machining Fixture Clamping
Dial in the exact 241 N safe clamping force against varying part heights by adjusting the extend stop from 5 to 80 mm without swapping actuators.
Packaging Line Diverters
Quickly reposition the diverter stroke on the fly during product changeovers, using the 75 mm adjustment window to handle different carton widths.
Press Fit Trial Positioning
Safely test insertion depths during initial setup by limiting the forward travel, preventing damage to components before finalizing the mechanical stop.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-75 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 SDAJ32X80-75 is the optimal choice when your application demands roughly 402.1 N of thrust but requires extensive on-site stroke tuning across a 75 mm window. Based on the 0.5 MPa push figure, a safe working load is approximately 241 N (about 60% capacity), translating to a vertical lift capability of around 20.5 kg with a 2:1 safety margin.
This model is highly recommended for setup-heavy production lines requiring frequent changeovers or trial positioning. Confirm your installation parameters: a 32 mm bore, 80 mm maximum stroke, 75 mm adjustment window, PT1/8 air port, female M6x1.0 rod-end thread, and no magnet. Remember that a plain cylinder does not hold position or load when air is lost or the valve is centered; the fixed bumper only decelerates near the end of travel. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–80 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 SDAJ32X80-75 FAQ
This 32 mm bore double-acting cylinder delivers a push force of 402.1 N and a pull force of 345.6 N at 0.5 MPa. 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.
The external R (M10x1.25) screw mechanically limits the extend stroke, allowing you to set the forward end position anywhere between 5 mm and 80 mm. This SKU does not include a piston magnet; to use reed or electronic switches for position sensing, you must select the -S magnet option.
