Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-10
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-10 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 300mm 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 ACQJ32X300-10
The AirTAC ACQJ32X300-10 is a double-acting, single-rod JIS compact cylinder built for long-stroke, made-to-order applications requiring exact end-position tuning. It features a 300mm stroke with a 10mm adjustable window, allowing the extend stop to be set anywhere between 290mm and 300mm. Retract travel remains completely unaffected by this external limit. Because the piston area is unchanged, output force matches a standard ACQ exactly.
This 32mm bore variant pushes 402.1N and pulls 301.6N at 0.5MPa, operating via a PT1/8 port with a 16mm rod. It relies on fixed NBR elastomer bumpers for end-of-stroke deceleration rather than adjustable air cushions. The body includes magnetic-switch grooves, though this specific SKU ships without a magnet. Note that a 300mm stroke significantly exceeds the 100mm standard maximum for this bore size, classifying it as a long-stroke configuration.
Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-10 Technical Specifications
| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-10 |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 300 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 ACQJ32X300-10 Is Used
Extended-Reach Gauging
Sets a precise 290-300mm probe extension on a long-stroke coordinate measuring rig, allowing operators to dial in the exact contact depth without machining custom spacers.
Automated Assembly Line Changeover
Adjusts the extend endpoint on a 300mm stroke transfer arm when switching between product variants, using the external stop to rapidly accommodate different part widths.
Long-Stroke Material Handling
Fine-tunes the pusher stroke on a packaging conveyor that requires a 300mm extension to reach deep into a carton, ensuring gentle product placement via the fixed elastomer bumper.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-10 the Right Cylinder?
Selecting this model is ideal when you need extended reach beyond the 100mm standard max for a 32mm bore, alongside precise 290-300mm extend positioning. If a fixed 300mm stop is always sufficient, a standard ACQ32X300 avoids the external adjuster. For higher force, stepping up to a 40mm bore yields 628.3N push at 0.5MPa; stepping down to a 25mm bore provides 245.4N push. Confirm your ordering essentials: 32mm bore, 300mm full stroke, 10mm window, female M8x1.25 rod thread, and no magnet. Remember that a plain compact cylinder drifts on air loss, so specify an external rod lock if fail-safe load holding is required.
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 ACQJ32X300-10 FAQ
This 32mm bore cylinder delivers a push force of 402.1N and a pull force of 301.6N at 0.5MPa, with a push of 562.9N at 0.7MPa and a maximum push of 82kgf at 1.0MPa. The usable extend range is 290-300mm, achieved by shortening the 300mm full stroke by up to a 10mm window.
An external M12x1.25 threaded stop with a lock nut limits the extend travel, allowing on-machine tuning without changing parts. It changes stroke length only, so force remains identical to a standard ACQ. The cylinder uses fixed NBR elastomer bumpers at both ends for deceleration, not adjustable air cushions, and the retract stroke is unaffected.
