Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-30
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-30 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 ACQJ32X300-30
The ACQJ32X300-30 is a double-acting JIS compact cylinder built for applications requiring exact extend positioning. It features an external M12x1.25 threaded stop with a lock nut that limits the rod outward travel. You can fine-tune the end position directly on the machine, yielding a usable extend range of 270-300mm from the 300mm full stroke. The retract stroke remains completely unaffected.
Because the piston area stays the same, output force is identical to a standard ACQ of this bore. The adjuster alters stroke length only. This made-to-order long-stroke variant exceeds the 100mm standard maximum for a 32mm bore. It retains the compact riveted body, fixed NBR elastomer bumpers at each end, and magnetic-switch grooves, though this specific unit ships without a magnet.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-30 |
|---|---|
| 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 |
| 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 (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 ACQJ32X300-30 Is Used
Machine Tool Changeover
Adjusts the extend stop to accommodate different part lengths on a machining center without swapping out the entire actuator assembly.
Variable Package Diverters
Fine-tunes the pusher extension depth on a packaging line to handle varying carton widths on the fly during production runs.
Assembly Fixture Setup
Dials in the exact end position for clamping components during trial runs, allowing operators to set precise 270-300mm strokes.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X300-30 the Right Cylinder?
When sizing this actuator, consider the 402.1N push and 301.6N pull at 0.5MPa. If your application needs less force, stepping down to a 25mm bore provides 245.4N push, while moving up to a 40mm bore yields 628.3N push. If exact end-position tuning is unnecessary, a fixed-stroke ACQ cylinder will suffice. To order, confirm the 32mm bore, 300mm full stroke, 30mm adjuster window, female M8x1.25 rod thread, and PT1/8 port. Note that a plain cylinder does not hold its load on air loss; for fail-safe holding, 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 ACQJ32X300-30 FAQ
The usable extend range is 270-300mm, created by a 30mm adjustment window on a 300mm full stroke. Force is identical to a standard ACQ: 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82kgf at 1.0MPa.
An external M12x1.25 threaded screw with a lock nut limits the extend stroke length without changing the piston area, so force remains unchanged. The cylinder uses fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. While the body has sensor grooves, this model ships without a magnet.
