Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-10SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 80mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-10SB
The AirTAC ACQJ40X80-10SB is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 70 to 80 mm on the machine without swapping parts, while the retract stroke remains unaffected. It features a 16 mm piston rod, a male M14x1.5 rod-end thread, and a PT1/8 port.
Because the adjuster only alters stroke length and not piston area, the output force is identical to a standard ACQ of this bore. The cylinder delivers 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. It includes a built-in piston magnet for position sensing and fixed elastomer bumpers at both ends for end-of-stroke deceleration.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Full stroke | 80 mm |
| Adjuster thread | M12×1.25 |
| Port size | PT1/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Rod thread | M8×1.25 (F) / M14×1.5 (B) |
Specifications follow the official AirTAC ACQJ datasheet. The adjustable stop shortens the EXTEND stroke only; the piston area — and therefore the force — is the same as a standard ACQ of this bore. Adjustable window options: 10/20/30/40/50/75/100 mm.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
Force equals a standard ACQ of the same bore — the adjuster changes stroke length, not piston area. Actual usable force is lower due to friction; size with a safety margin.

Where the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-10SB Is Used
Machining Fixture Stops
Dial in the exact 70 to 80 mm extend position on a CNC machining fixture to accommodate raw part tolerances without fabricating new spacer blocks.
Packaging Changeover
Rapidly adjust the extend endpoint during packaging line product changeovers to hit different carton depths using the external M12x1.25 stopper screw.
Assembly Press Trials
Set trial end positions on automated assembly presses to test insertion depths, relying on the fixed elastomer bumper to absorb end-of-stroke impact.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-10SB the Right Cylinder?
If 527.8 N of retract force at 0.5 MPa is insufficient, stepping up to the 50 mm bore provides 824.6 N of pull force, whereas dropping to the 32 mm bore offers 301.6 N of pull force. A fixed-stroke ACQ cylinder is adequate if your extend endpoint never requires adjustment. To order this adjustable version, confirm the 40 mm bore, 80 mm full stroke, 10 mm window, the S magnet for electronic or reed switches, and the B male rod thread.
Quick checklist
- ✓ Need on-machine end-position tuning?
- ✓ Full stroke and adjust window (mm)
- ✓ Force at your working pressure
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
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 adjuster nut after setting the stop.
- check The stop limits the EXTEND stroke only.
- check Avoid side load on the short piston rod.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-10SB FAQ
The usable extend range is 70 to 80 mm, set by the 10 mm adjustable window. Force is identical to a standard ACQ: push is 628.3 N and pull is 527.8 N at 0.5 MPa, push is 879.6 N at 0.7 MPa, and maximum push is 128 kgf at 1.0 MPa.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke, while the retract stroke stays unaffected. The force is unchanged because piston area remains the same. Fixed NBR bumpers handle deceleration, and the included S magnet works with reed or solid-state electronic switches.
