Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-75
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-75 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 10 to 85 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-75
The AirTAC SDAJ32X85-75 is a double-acting compact cylinder featuring an external adjustable extend stop. A M10x1.25 adjuster screw lets you dial the outward stroke on-site anywhere from 10 to 85 mm, eliminating the need for shims or part swaps during changeovers. Because the mechanism only restricts travel length, output force remains identical to a standard 32 mm bore SDA unit, delivering 402.1 N of push at 0.5 MPa.
The short riveted body drastically cuts axial mounting depth, fitting where round-body alternatives cannot. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so position sensing is not supported without switching to the -S variant.
Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-75 Technical Specifications
| Model | Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-75 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 85 mm |
| Adjustable range | 10 – 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 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 SDAJ32X85-75 Is Used
Tooling Changeover Stations
Dial the extend stop from 10 to 85 mm via the M10x1.25 screw to accommodate varying fixture heights during rapid product line changeovers.
Trial Positioning Rigs
Safely test multiple extend endpoints on the machine without disassembling the assembly, relying on a stable 402.1 N push force at 0.5 MPa.
Variable Depth Flap Folding
Adjust the mechanical stop on the fly for different carton depths, letting the fixed NBR bumper absorb the end shock at cycle completion.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-75 the Right Cylinder?
When sizing this 32 mm bore actuator, evaluate your neighbors: the SDAJ25 provides 245.4 N push at 0.5 MPa, while the SDAJ40 jumps to 628.3 N. At 402.1 N, this model yields a safe working load around 241 N (roughly 60 percent of the 0.5 MPa figure) and can vertically lift about 20.5 kg with a 2:1 safety margin. It is the right pick for setups demanding frequent on-machine stroke tuning.
Verify your parameters: 32 mm bore, 85 mm max stroke, 75 mm window, PT1/8 port, female M6x1.0 rod thread, and no magnet. Remember that a plain cylinder drifts when air is lost or the valve centers—the fixed bumper only softens the impact near the end and acts as a mechanical stop, not a lock. For secure load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–85 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 SDAJ32X85-75 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.
Turning the R (M10x1.25) external screw shortens the extend end position by up to 75 mm, giving a usable range of 10 to 85 mm. It sets the mechanical stop and does not alter the output force.
