Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-40
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-40 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 40 to 80 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-40
The AirTAC SDAJ32X80-40 is a compact double-acting single-rod cylinder featuring an external extend stop. By turning the R (M10x1.25) adjuster screw, you can dial the forward end-position anywhere between 40 and 80 mm directly on the machine, eliminating shims or part swaps. Because the mechanism only sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering 402.1 N of push at 0.5 MPa.
Its short riveted body drastically cuts axial mounting depth where larger profile or round-body units fail to fit. End-of-travel kinetic energy is managed solely by a fixed NBR bumper, which decelerates the piston but is not an adjustable air cushion. Note this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Max stroke | 80 mm |
| Adjustable range | 40 – 80 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 SDAJ32X80-40 Is Used
Machining Clamp Tuning
Dial the extend stop between 40 and 80 mm to perfect clamping depth on raw castings of varying dimensions without machining custom spacers.
Carton Flap Folding
Adjust the mechanical stop on-site to match different box heights, ensuring precise flap positioning before tape application.
Press Fit Depth
Set exact insertion depths for bearing presses, relying on the fixed NBR bumper to absorb the 402.1 N end-of-stroke impact.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-40 the Right Cylinder?
When sizing this 32 mm bore unit, verify your thrust requirements both ways: stepping down to an SDAJ25 yields 245.4 N push at 0.5 MPa, while moving up to an SDAJ40 provides 628.3 N. At 0.5 MPa, this model offers a safe working load of roughly 241 N (about 60 percent of its rated output) and can vertically lift approximately 20.5 kg with a 2:1 safety margin. Choose this adjustable variant if your fixture design requires frequent on-site stroke tuning or trial positioning.
Confirm your parameters: 32 mm bore, 80 mm maximum stroke, 40 mm adjustment window, and PT1/8 port. This base configuration has a female M6x1.0 rod-end thread and no magnet. Keep in mind the fixed NBR bumper only absorbs end shock; a plain cylinder cannot hold a load if air pressure drops or the valve centers. For suspended loads, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 40–80 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 SDAJ32X80-40 FAQ
This double-acting cylinder delivers 402.1 N push and 345.6 N pull at 0.5 MPa, or 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum output is 82 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa at speeds of 30-500 mm/s.
The R (M10x1.25) screw mechanically shortens the extend stroke by up to 40 mm, giving a usable forward range of 40 to 80 mm. Retract remains full length. This specific SKU has no piston magnet and cannot accept switches; you must specify the -S option for reed or electronic sensing.
