Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-75B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-75B is a genuine double-acting COMPACT cylinder (Ø40mm bore) whose extend end-position is set by an external M12×1.25 adjustment screw. You can dial the stroke anywhere from 0 to 75 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-75B
The AirTAC SDAJ40X75-75B is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. An M12x1.25 screw lets you dial the outward stroke down by up to 75mm directly at the machine, yielding a usable extend range of 0-75mm without swapping shims or parts. Because the adjuster only sets the mechanical stop position, output force remains identical to a standard SDA of this bore, providing 628.3N push at 0.5MPa.
Its short riveted body drastically cuts axial mounting depth where round-body or profile cylinders cannot fit. This specific SKU includes a male M14x1.5 piston rod thread and lacks a piston magnet, meaning it cannot host reed or electronic switches. End shock is managed solely by a fixed NBR bumper, which decelerates the piston near the end of travel rather than acting as a lock.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Max stroke | 75 mm |
| Adjustable range | 0 – 75 mm |
| Adjuster thread (R) | M12×1.25 |
| Port size | PT1/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M8×1.25 F / M14×1.5 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 SDAJ40X75-75B Is Used
Machine Changeovers
Dial the extend stop from 0 to 75mm via the M12x1.25 screw to adapt a 628.3N push force for different product formats without machining new spacers.
Carton Flap Folding
Fine-tune the male M14x1.5 rod extension on the line to accommodate varying box heights, ensuring precise mechanical positioning before the fixed NBR bumper takes the shock.
Trial Positioning
Safely test clamping depths on prototype parts by adjusting the outward stop, keeping the safe working load near 377N to prevent overdriving the workpiece.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-75B the Right Cylinder?
When sizing this unit, compare its 628.3N push at 0.5MPa against neighbouring bores: a 32mm bore provides 402.1N, while a 50mm bore yields 981.7N. A safe working load is roughly 377N (about 60% of the 0.5MPa figure), translating to a vertical lift capacity of approximately 32kg with a 2:1 safety margin. Choose this 40mm option when your setup requires on-site stroke tuning to perfect end positions during changeovers.
Verify your requirements for a 40mm bore, 75mm maximum stroke, and a 75mm adjustment window. This variant features a PT1/8 port, a male M14x1.5 rod end, and no magnet. Note that a plain cylinder does not hold a load if air pressure drops or the valve is centred; the piston will drift. 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 0–75 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 M12×1.25 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 SDAJ40X75-75B FAQ
At 0.5MPa this 40mm bore cylinder provides 628.3N push and 527.8N pull. At 0.7MPa it provides 879.6N push and 738.9N pull. The theoretical maximum push is 128kgf at 1.0MPa.
Turning the M12x1.25 adjuster screw shortens the extend end position by up to 75mm, giving a usable extend range of 0-75mm. The screw sets the mechanical stop and does not alter the force. This SKU lacks the -S magnet, so it cannot accept reed or electronic switches.
