About the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-30
The AirTAC ACQJ32X25-30 is a double-acting JIS compact cylinder featuring a 32mm bore and 25mm full stroke. An external M12x1.25 threaded stop with a lock nut limits the extend end position, allowing you to fine-tune the stroke on the machine without swapping parts. The usable extend range is 0-25mm, while the retract stroke remains completely unaffected.
Because the piston area is unchanged, force output is identical to a standard ACQ of this bore, delivering 402.1N push and 301.6N pull at 0.5MPa. The unit uses a PT1/8 port, a 16mm piston rod with an M8x1.25 female thread, and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration. The body includes magnetic-switch grooves, though this specific configuration ships without a magnet.

| Bore size | Ø32 mm |
| Full stroke | 25 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 |

| 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 302 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 ACQJ32X25-30 Is Used
Machining Fixture Clamping
Dial in the exact clamping extension on a machining fixture to accommodate raw material thickness variations without manufacturing custom spacer plates.
Packaging Line Changeover
Rapidly adjust the extend end stop during packaging line product changeovers to hit different carton pusher depths quickly and accurately.
Assembly Press Setup
Establish precise trial end positions on an electronic assembly press, safely testing engagement depths before finalizing the mechanical hard stop.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X25-30 the Right Cylinder?
When sizing this 32mm bore actuator, stepping down to a 25mm bore reduces the 0.5MPa push force to 245.4N, whereas stepping up to a 40mm bore increases it to 628.3N. If your application never requires altering the extend end-position, a fixed-stroke ACQ cylinder will suffice and simplify assembly. To order correctly, confirm the 32mm bore, 25mm full stroke, 30mm adjustable window, female rod thread, and whether you need the -S magnet option for sensing.
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 ACQJ32X25-30 FAQ
This cylinder provides a push force of 402.1N and a pull force of 301.6N at 0.5MPa, and a push force of 562.9N at 0.7MPa. The maximum push force is 82kgf at 1.0MPa. The full stroke is 25mm with a 30mm adjustable window, yielding a usable extend range of 0-25mm. It features a PT1/8 port, a 16mm rod, an M8x1.25 female rod-end thread, and an M12x1.25 external adjuster thread.
No, the adjuster only limits how far the rod extends, leaving the piston area untouched, so force remains identical to a standard ACQ. The retract stroke is also unaffected. The cylinder relies on fixed NBR elastomer bumpers for end-of-stroke deceleration rather than adjustable air cushions. Note that this model ships without a magnet, but the body retains sensor grooves for adding reed or solid-state switches if needed.
