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

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-40
The AirTAC SDAJ32X85-40 is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. An M10x1.25 adjuster screw lets you dial the outward stroke down on-site from the full 85 mm to a minimum of 45 mm without changing parts. Because the adjuster only sets the mechanical stop, output force remains identical to a standard SDA of this bore, yielding 402.1 N push at 0.5 MPa.
The short riveted body saves axial mounting depth where round-body or profile cylinders will not fit. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. This specific SKU ships without a piston magnet, so it cannot host reed or electronic switches.

| Model | Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-40 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 85 mm |
| Adjustable range | 45 – 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 40 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 SDAJ32X85-40 Is Used
Tooling Changeover
Dial the extend stop from 45 to 85 mm via the M10x1.25 screw to accommodate varied part heights during production line changeovers without swapping hardware.
Vertical Lift Jigs
Lift payloads up to 20.5 kg safely with a 2:1 margin, relying on the 402.1 N push force while fitting into shallow machine cavities via the compact riveted body.
Trial Positioning
Set precise extend endpoints during R&D prototyping by turning the external stop screw, avoiding the need to dismantle the PT1/8 port plumbing for shims.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-40 the Right Cylinder?
When sizing this 32 mm bore, evaluate your neighbours: stepping down to an SDAJ25 provides 245.4 N push at 0.5 MPa, while moving up to an SDAJ40 yields 628.3 N. This SDAJ32X85-40 strikes a middle ground, offering a safe working load of roughly 241 N (about 60 percent of the 0.5 MPa rating) and a vertical lift capacity near 20.5 kg with a 2:1 margin.
Choose this model if your fixture requires frequent on-machine stroke tuning during changeovers. Confirm your parameters: 32 mm bore, 85 mm max stroke, 40 mm adjust window, PT1/8 port, female M6x1.0 rod thread, and no magnet. Remember that a plain cylinder does not hold a load on air loss; the fixed bumper only decelerates near the end. 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 45–85 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 SDAJ32X85-40 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 delivers 563 N push and 483.8 N pull. The theoretical maximum push is 82 kgf at 1.0 MPa.
The M10x1.25 R screw acts as a mechanical stop to shorten the extend stroke anywhere between 45 and 85 mm. It does not alter the 402.1 N force and is not a mid-stroke lock. Note this SKU lacks the -S magnet, so it cannot accept reed or electronic switches.
