Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-100S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-100S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 80mm 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 ACQJ32X80-100S
The AirTAC ACQJ32X80-100S is a double-acting JIS compact cylinder with a 32mm bore and an external M12x1.25 threaded stop. By turning this adjuster rod, you can fine-tune the extend end position on the machine, yielding a usable forward travel window of 0-80mm from the 80mm full stroke. The retract distance remains completely unaffected.
Because the piston area is unchanged, output force equals a standard ACQ, delivering 402.1N push and 301.6N pull at 0.5MPa. It features a fixed NBR elastomer bumper at each end and a built-in magnet for position sensing. The unit operates at 30-500mm/s with a PT1/8 port and a 16mm piston rod.

| 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 ACQJ32X80-100S Is Used
Machining Fixture Tuning
Dial in the exact clamping reach on a CNC lathe without machining new spacer blocks.
Product Changeover Stops
Quickly reposition the extend endpoint to accommodate different packaging widths.
Assembly Press Trials
Safely test intermediate insertion depths for electronic connector alignment.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-100S the Right Cylinder?
When sizing this 32mm bore, the adjacent ACQJ25 delivers 245.4N push while the ACQJ40 provides 628.3N at 0.5MPa. If your end position never varies, a fixed-stroke ACQ32X80 is simpler. To order this version, confirm the 32mm bore, 80mm base stroke, 100mm adjust window, the -S magnet, and your rod thread preference.
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 ACQJ32X80-100S FAQ
It generates 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum 82kgf push at 1.0MPa. The full stroke is 80mm, but the external stop allows an adjustable usable extend range of 0-80mm via the 100mm window.
No, the adjuster only limits forward travel distance, keeping output identical to a standard ACQ. Deceleration relies on a fixed elastomer bumper, and since it lacks a rod lock, the load will drift on air loss unless you add an external locking mechanism.
