Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X75-30S
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X75-30S 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 45 to 75 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X75-30S
The AirTAC SDAJ32X75-30S is a compact double-acting single-rod cylinder featuring an external extend stop. An M10x1.25 adjuster screw lets you dial the forward end-position anywhere between 45 and 75 mm directly on the machine, eliminating the need for shims or part swaps during changeovers. Because the mechanism sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering 402.1 N push at 0.5 MPa.
The short riveted body minimizes axial mounting depth, fitting where larger profile cylinders cannot. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Equipped with a built-in piston magnet (-S), this unit supports AirTAC reed or electronic solid-state switches for precise position sensing.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 75 mm |
| Adjustable range | 45 – 75 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 SDAJ32X75-30S Is Used
Variable Height Gauging
Dial the extend stop between 45 and 75 mm to gauge multiple part heights on the same fixture without machining custom spacers.
Carton Flap Folding
Adjust the M10x1.25 screw on-site to perfectly time the folding arm for varying box widths during rapid product changeovers.
Trial Positioning Stops
Use the 402.1 N push force to test clamping depths on prototype parts, fine-tuning the mechanical stop before finalizing a hard setup.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X75-30S the Right Cylinder?
When sizing this 32 mm bore, compare its 402.1 N push at 0.5 MPa against adjacent bores: stepping down to SDAJ25 yields 245.4 N, while moving up to SDAJ40 provides 628.3 N. A practical safe working load is roughly 241 N (about 60% 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 specific model if your fixture requires frequent on-machine stroke tuning to accommodate varying part heights.
Verify your requirements against these specs: 32 mm bore, 75 mm maximum stroke, 30 mm adjustment window, PT1/8 port, and a female M6x1.0 rod-end thread. The -S code confirms the internal magnet is present for switch integration. Remember that a plain cylinder drifts when air is lost or the valve is centered; the fixed bumper only decelerates near the end of travel and does not act as a lock. For secure 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 45–75 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 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 SDAJ32X75-30S FAQ
At 0.5 MPa this 32 mm bore cylinder provides 402.1 N push and 345.6 N pull. At 0.7 MPa it provides 563 N push and 483.8 N pull. The theoretical maximum push is 82 kgf at 1.0 MPa.
The M10x1.25 R screw shortens the extend stroke by up to 30 mm, yielding a usable 45 to 75 mm forward range while retract remains full. The -S suffix denotes a built-in piston magnet compatible with AirTAC reed or electronic solid-state switches for end-position sensing.
