Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-20S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-20S 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 ACQJ32X80-20S
The AirTAC ACQJ32X80-20S is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 60 mm up to the full 80 mm directly on your machine without swapping parts. The retract stroke remains completely unaffected. A built-in piston magnet (-S) is included for position sensing.
Because the adjuster only shortens travel length and not the piston area, output force is identical to a standard ACQ of this bore. The 32 mm bore delivers 402.1 N push and 301.6 N pull at 0.5 MPa. It features a 16 mm rod, a PT1/8 port, and fixed elastomer bumpers at both ends rather than adjustable pneumatic cushions.

| Bore size | Ø32 mm |
| Full stroke | 80 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 ACQJ32X80-20S Is Used
CNC Tooling Changeover
Dial in the extend stroke from 60 to 80 mm when swapping machining fixtures on a CNC lathe, ensuring the toolhead hits the exact new working depth without remounting hardware.
Carton Flap Folding Stops
Adapt a packaging line on the fly for varying box heights by tweaking the external stop, allowing precise flap folding positions for different product runs.
Press Fit Depth Trials
Safely test different insertion depths on an assembly press by adjusting the rod extension in millimeter increments before locking down the final production setting.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-20S the Right Cylinder?
If your application needs less thrust, the 25 mm bore yields 245.4 N push at 0.5 MPa, while stepping up to the 40 mm bore provides 628.3 N push. Choose this 32 mm model when you need around 402.1 N of push force and on-machine extend tuning. If the exact 80 mm end position is permanently fixed and never requires adjustment, a standard ACQ cylinder will suffice. When ordering, confirm the 32 mm bore, 80 mm full stroke, 20 mm adjuster window, the -S magnet for reed or solid-state switches, and the default female M8x1.25 rod-end thread.
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 ACQJ32X80-20S FAQ
It provides 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 full stroke is 80 mm with a 20 mm adjustment window, giving a usable extend range of 60 to 80 mm. Retract stroke remains at the full 80 mm.
An external M12x1.25 threaded stop with a lock nut mechanically limits how far the rod extends, shortening the stroke length without changing the piston area, so force is identical to a standard ACQ. Deceleration relies on fixed NBR elastomer bumpers at both ends, not an adjustable air cushion. The -S magnet supports both reed and electronic solid-state switches.
