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

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-10B
The AirTAC SDAJ32X85-10B is a double-acting compact cylinder featuring a male-thread piston rod and an external extend stop. A built-in M10x1.25 adjuster screw lets you dial the forward stroke down by 10 mm directly at the machine, yielding a usable extend range of 75 to 85 mm without swapping shims or parts. Retract remains full length. Because the adjuster only sets the mechanical stop, output force equals a standard SDA of this bore, delivering 402.1 N of push at 0.5 MPa.
This thin riveted body saves axial mounting depth where round-body or profile cylinders cannot fit. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note this specific SKU lacks a piston magnet, so magnetic switches cannot be used; the -S variant is required for reed or electronic sensing.

| Model | Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-10B |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 85 mm |
| Adjustable range | 75 – 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 10 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 SDAJ32X85-10B Is Used
Tooling Setup Calibration
Dial in the 75-85 mm extend stop during initial fixture commissioning to precisely set the M10x1.25 male rod contact point without machining spacers.
Carton Flap Folding
Fine-tune the 402.1 N push stroke on-site to accommodate varying box heights, ensuring perfect flap closure without crushing the packaging.
Bending Stroke Limit
Use the 10 mm adjustment window to set a hard mechanical stop for light metal forming, guaranteeing consistent bend depths across material batches.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-10B the Right Cylinder?
When sizing this unit, compare the 402.1 N push at 0.5 MPa against its neighbors: stepping down to a 25 mm bore yields 245.4 N, while a 40 mm bore provides 628.3 N. For your dynamic loads, a safe working target is roughly 241 N (about 60% of the 0.5 MPa figure), which translates to a vertical lift capacity near 20.5 kg with a 2:1 margin. Choose this 32 mm model when your application requires moderate force in a tight footprint.
This version includes the -B option for a male M10x1.25 rod end and a 10 mm adjustment window. It operates at 30-500 mm/s with a PT1/8 port. Remember that a plain SDAJ does not hold position if air pressure drops or the valve centers—the fixed bumper only decelerates near the end of stroke. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 75–85 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 SDAJ32X85-10B FAQ
At 0.5 MPa it provides 402.1 N push and 345.6 N pull. At 0.7 MPa it provides 563 N push and 483.8 N pull. The theoretical maximum push is 82 kgf at 1.0 MPa.
The M10x1.25 R screw mechanically shortens the extend stroke from 85 mm down to 75 mm. It does not alter force or lock mid-stroke. The cylinder cannot hold a load on air loss; use an external rod lock for holding.
