About the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X60-40S
The AirTAC ACQJ32X60-40S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut on the extend side. This mechanism allows you to fine-tune the extend end position on the machine, providing a usable extend range of 20-60mm from the 60mm full stroke, 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.
This 32mm bore unit delivers 402.1N of push force and 301.6N of pull force at 0.5 MPa. It incorporates a fixed elastomer NBR bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. Equipped with the -S magnet, the body includes sensor grooves compatible with both reed and solid-state electronic switches for position detection.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 60 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 ACQJ32X60-40S Is Used
Machining Fixture Positioning
Dial in the exact clamping extension on a CNC machining fixture during initial setup or when swapping part programs without machining new stop collars.
Packaging Changeover Stops
Adapt the extend push-off distance for different carton widths on a packaging line, utilizing the 20-60mm range to handle product variability quickly.
Assembly Press Trial
Test and set precise engagement depths on an assembly press, finding the optimal end position before locking the M12x1.25 adjuster nut in place.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X60-40S the Right Cylinder?
Choosing this 32mm bore gives 402.1N push at 0.5MPa. Stepping down to a 25mm bore drops push to 245.4N, whereas a 40mm bore raises push to 628.3N. If your application never requires end-position adjustments, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 32mm bore, 60mm full stroke, 40mm adjuster window, the -S magnet option, 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 ACQJ32X60-40S FAQ
The 32mm bore 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 60mm with a 40mm adjustment window, yielding a usable extend range of 20-60mm.
No, the external M12x1.25 threaded stop changes only the extend stroke length, not the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for deceleration, meaning there is no adjustable air cushion.
