Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-30
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-30 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 55 to 85 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-30
The AirTAC SDAJ32X85-30 is a double-acting compact cylinder featuring an external extend stop. An M10x1.25 adjuster screw lets you dial the forward stroke down by 30 mm, yielding a usable forward range of 55 to 85 mm directly on the machine. Because the mechanism sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, providing 402.1 N of push at 0.5 MPa.
The short riveted body drastically cuts axial mounting depth where round-body units fail to fit. End shock is managed solely by a fixed NBR bumper, which decelerates the piston near the end of travel but is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet and cannot accept reed or electronic switches.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 85 mm |
| Adjustable range | 55 – 85 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 SDAJ32X85-30 Is Used
Tooling Changeover
Dial the M10x1.25 screw to shift the extend stop from 85 mm back to 55 mm during fixture swaps, eliminating the need to machine custom spacers for varied part heights.
Sorting Diverter
Set the exact 402.1 N push required to deflect mixed carton sizes on a packaging line, fine-tuning the extend endpoint on-site to prevent crushing delicate goods.
Prototype Positioning
Sweep the 30 mm adjustment window during R&D trial cycles to find the optimal reach for a 20.5 kg vertical lift before locking down the final mechanical stop.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-30 the Right Cylinder?
When sizing this 32 mm bore, evaluate both neighbours: the SDAJ25 yields 245.4 N push at 0.5 MPa, whereas the SDAJ40 provides 628.3 N. This model sits perfectly in the middle, delivering a safe working load of roughly 241 N, which translates to a vertical lift capacity of about 20.5 kg with a 2:1 safety margin. Choose the 32 mm if your changeover process demands on-site stroke tuning between 55 and 85 mm without swapping shims.
Verify your parameters: 32 mm bore, 85 mm maximum stroke, 30 mm window, PT1/8 port, female M6x1.0 rod thread, and no magnet. Remember that a plain actuator will not hold a load if air pressure drops or the valve centers; the bumper only decelerates the stroke end. 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 55–85 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 SDAJ32X85-30 FAQ
At 0.5 MPa this 32 mm bore unit pushes with 402.1 N and pulls with 345.6 N. At 0.7 MPa the push is 563 N and pull is 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa.
Turning the external R (M10x1.25) screw mechanically shortens the forward endpoint from 85 mm down to 55 mm. This screw acts strictly as a stop and does not alter force or lock the piston mid-stroke. Because this SKU lacks a -S magnet, it cannot accept magnetic switches.
