Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X120-75S
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X120-75S 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 120 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X120-75S
The AirTAC SDAJ32X120-75S is a compact double-acting single-rod cylinder featuring an external extend stop. A built-in piston magnet enables position sensing with AirTAC reed or electronic switches. The short riveted body minimizes axial mounting depth, fitting where round-body units cannot.
By turning the R (M10x1.25) adjuster screw, you can dial the extend position anywhere between 45 and 120 mm directly on the machine. This mechanical stop sets the end point without altering the bore area, delivering a push force of 402.1 N at 0.5 MPa. A fixed NBR bumper decelerates the stroke end, operating reliably at speeds of 30-500 mm/s.

| Model | Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X120-75S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 120 mm |
| Adjustable range | 45 – 120 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 SDAJ32X120-75S Is Used
Trial Positioning Jigs
Dial the extend stop between 45 and 120 mm via the R screw to find the exact 402.1 N contact point during prototype runs, avoiding part changes.
Changeover Diverters
Quickly reset the mechanical stop for different package lengths on a packaging line, using the built-in magnet to confirm the retracted home position.
Variable Depth Indexing
Set precise material push depths on the fly without shims, relying on the fixed NBR bumper to absorb the end shock at operating speeds up to 500 mm/s.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X120-75S the Right Cylinder?
When sizing this 32 mm bore, evaluate both neighbors: the SDAJ25 yields 245.4 N push at 0.5 MPa, whereas the SDAJ40 provides 628.3 N. This model offers a safe working load of roughly 241 N (about 60% of the 402.1 N figure) and can vertically lift approximately 20.5 kg with a 2:1 margin. Choose the SDAJ32X120-75S for setup-heavy lines requiring frequent on-machine stroke tuning.
Confirm your parameters: 32 mm bore, 120 mm max stroke, 75 mm adjust window, PT1/8 port, female M6x1.0 rod thread, and the -S magnet. Note that a plain cylinder does not hold its load on air loss or valve centering; the fixed bumper only decelerates near the end. 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 45–120 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 SDAJ32X120-75S 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 push of 82 kgf at 1.0 MPa.
