Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X125-10
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X125-10 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 ACQJ32X125-10
The AirTAC ACQJ32X125-10 is a double-acting, single-rod JIS compact cylinder built for on-machine extend length tuning. An external M12x1.25 threaded stop with lock nut lets you shorten the outward travel by up to 10 mm. This yields a usable extend span of 115 to 125 mm, while the return stroke remains completely unaffected. Because the 32 mm piston area stays constant, output force matches a standard ACQ exactly: 402.1 N push and 301.6 N pull at 0.5 MPa.
This unit is a made-to-order long-stroke variant, as the 125 mm travel exceeds the 100 mm standard maximum for this bore size. It features a fixed NBR elastomer bumper at each end for end-of-stroke deceleration and integrated sensor grooves, though this specific configuration ships without a magnet. Operating pressure spans 0.15 to 1.0 MPa, and the PT1/8 port pairs with a 16 mm rod featuring an M8x1.25 female end thread.

| Bore size | Ø32 mm |
| Full stroke | 125 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 ACQJ32X125-10 Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC milling fixture without machining new spacer plates during setup changes.
Packaging Diverter Arms
Fine-tune the pusher stroke length on a packaging line to accommodate varying carton depths on the fly.
Assembly Press Positioning
Establish precise trial end positions for a press operation in automotive component assembly before locking the nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X125-10 the Right Cylinder?
When sizing this actuator, consider the 32 mm bore generating 402.1 N of push force at 0.5 MPa. Stepping down to a 25 mm bore yields 245.4 N, whereas moving up to a 40 mm bore provides 628.3 N. If your application never requires altering the end position, a fixed-stroke ACQ32X125 will achieve the same clamping power without the external adjuster hardware. To order this adjustable version correctly, confirm the 32 mm bore, 125 mm full stroke, 10 mm window, female rod thread, and whether you need the S magnet option for electronic or reed switch 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 ACQJ32X125-10 FAQ
The usable extend range is 115 to 125 mm. The force is identical to a standard ACQ of the same bore: 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The adjuster only alters travel length, not the piston area.
An external M12x1.25 threaded screw with a lock nut limits the outward stroke, allowing on-site tuning without replacing parts. The cylinder uses fixed NBR elastomer bumpers for deceleration, not an adjustable air cushion. A standard compact cylinder will not hold a load on air loss; for fail-safe holding, install an external rod lock or pilot-operated check valve.
