Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X125-10S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X125-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 125mm 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 ACQJ32X125-10S
The ACQJ32X125-10S is a double-acting, single-rod JIS compact cylinder featuring an external adjustable extend stop. A threaded rod with a lock nut lets you fine-tune the extend end position on the machine without swapping parts. This long-stroke made-to-order variant provides a 125mm full stroke with a 10mm shortening window, yielding a usable extend range of 115-125mm. The retract stroke remains completely unaffected.
Because the piston area is unchanged, the output force is identical to a standard ACQ of the same bore. At 0.5 MPa it delivers 402.1N of push force and 301.6N of pull force. The unit includes a built-in piston magnet for use with reed or solid-state switches, and relies on a fixed NBR elastomer bumper at each end for end-of-travel deceleration rather than an adjustable air cushion.

| 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 ACQJ32X125-10S Is Used
Machining Fixture Clamps
Dial in the exact clamping extension on a CNC lathe fixture during setup, allowing 115 to 125mm of travel to accommodate varying raw stock lengths without machining new stops.
Packaging Changeover Stops
Adjust the pusher end position on a cartoning machine within seconds when switching between different product box widths, utilizing the external M12x1.25 adjuster thread.
Assembly Press Positioning
Set precise trial end positions for pressing bearings on an automated line, tweaking the stroke by up to 10mm on the equipment to find the optimal seating depth before locking the nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X125-10S the Right Cylinder?
When sizing this 32mm bore actuator, consider the adjacent standard options: a 25mm bore yields 245.4N push at 0.5 MPa, while a 40mm bore provides 628.3N. If your extend position never needs on-the-fly tuning, a fixed-stroke ACQ cylinder will suffice. Confirm your ordering essentials: 32mm bore, 125mm full stroke, 10mm window, the S magnet option, and the default female M8x1.25 rod-end thread. Note that for fail-safe load holding during air loss, you must add an external rod lock or pilot-operated check valve.
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 ACQJ32X125-10S FAQ
This 32mm bore cylinder delivers 402.1N push and 301.6N pull at 0.5 MPa, 562.9N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The full stroke is 125mm with a 10mm adjustable window, giving a usable extend range of 115-125mm. It features a PT1/8 port, an M12x1.25 external adjuster thread, and an M8x1.25 female rod-end thread.
No, the external threaded stop alters only the extend stroke length, not the piston area, so force remains identical to a standard ACQ. The retract stroke is unaffected. Deceleration is handled by a fixed elastomer bumper at each end, not an adjustable air cushion, so you may need an external shock absorber for high-energy loads. The included S magnet works with both reed and electronic solid-state switches.
