Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-75B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-75B 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 5 to 80 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-75B
The AirTAC SDAJ32X80-75B is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. Turning the R (M10x1.25) screw lets you dial the extend end-position anywhere between 5 and 80 mm directly on your machine, eliminating the need for shims or part swaps during changeovers. Retract remains a full 80 mm stroke. Because the adjuster sets the mechanical stop rather than the piston area, force equals a standard SDA of this bore, delivering 402.1 N push at 0.5 MPa.
This unit includes a male M10x1.25 piston rod thread and lacks a piston magnet, meaning it cannot host reed or electronic switches. The short riveted body minimizes axial mounting depth where space is tight. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Operating speed ranges from 30-500 mm/s across a 0.15-1.0 MPa pressure range.

| 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 SDAJ32X80-75B Is Used
Machining Clamp Depth
Dial the extend stop from 5 to 80 mm to set exact clamping depth on machining fixtures, absorbing raw part tolerances without fabricating custom spacers.
Rapid Format Changeover
Adjust the mechanical stop on-site during packaging line format changes to accommodate varying carton lengths quickly and keep downtime minimal.
Prototype Trial Positioning
Sweep the extend stroke across its 75 mm window during prototype assembly to find the optimal push-off distance before locking the R screw down.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-75B the Right Cylinder?
When sizing this 32 mm bore, evaluate your neighbors: stepping down to an SDAJ25 yields 245.4 N push at 0.5 MPa, while stepping up to an SDAJ40 provides 628.3 N push at 0.5 MPa. For this model, a safe working load is roughly 241 N (about 60% of the 402.1 N figure at 0.5 MPa), translating to a vertical lift capacity of approximately 20.5 kg with a 2:1 safety margin. Choose this specific 80 mm stroke with a 75 mm window if your fixture requires extensive trial positioning or frequent on-machine stroke tuning.
Confirm the 32 mm bore, 80 mm stroke, 75 mm adjust window, and PT1/8 port match your pneumatic layout. This SKU uses a male M10x1.25 rod thread (option B) and has no magnet (no -S), so position sensing is unavailable unless you switch to an -S variant. Remember that a plain cylinder does not hold its load on air loss or valve centering; the piston drifts and the fixed bumper only decelerates near the stroke end. 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 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 SDAJ32X80-75B FAQ
This 32 mm bore double-acting cylinder delivers 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 of 82 kgf at 1.0 MPa.
The external M10x1.25 R screw acts as a mechanical stop, allowing you to shorten the extend stroke from the 80 mm maximum down to 5 mm. It does not alter the 402.1 N force output and is not a mid-stroke lock.
