About the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X20-10
The AirTAC ACQJ32X20-10 is a double-acting JIS compact cylinder featuring an external extend stop. A threaded M12x1.25 rod-end adjuster with a lock nut lets you fine-tune the forward end position on the machine. The usable extend range spans 10 to 20mm, while the retract stroke remains completely unaffected.
Because the piston area stays the same, output force is identical to a standard ACQ of this bore. You get 402.1N push and 301.6N pull at 0.5MPa. The unit relies on a fixed NBR elastomer bumper for end-of-stroke deceleration and includes sensor grooves, though this specific SKU ships without a magnet.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 20 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 ACQJ32X20-10 Is Used
Product Changeover Stops
Quickly alter the extend endpoint from 10 to 20mm when switching between part families on a machining line, avoiding the need to swap out physical spacer rings.
Trial End Positions
Dial in the exact clamping depth on test jigs by turning the external M12x1.25 adjuster, locking the nut once the perfect 12mm forward position is found.
Setup-Varying Fixtures
Adapt a packaging folder's push-off distance on the fly for various carton sizes, using the full 10mm adjustment window to handle smaller boxes.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X20-10 the Right Cylinder?
If your setup needs less push, the 25mm bore yields 245.4N at 0.5MPa, whereas stepping up to a 40mm bore provides 628.3N. A fixed-stroke ACQ is adequate if your end position never requires tweaking. When ordering, verify the 32mm bore, 20mm full stroke, 10mm adjust window, female M8x1.25 rod thread, and PT1/8 port.
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 ACQJ32X20-10 FAQ
It provides 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. The full stroke is 20mm with a 10mm adjustable window, giving a usable extend range of 10-20mm.
The external threaded stop limits how far the rod extends without altering the piston area, meaning force stays identical to a standard ACQ. Deceleration relies on a fixed NBR elastomer bumper, not an adjustable air cushion. The body has sensor grooves, but this model ships without a magnet.
