About the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X40-10S
The AirTAC ACQJ32X40-10S is a double-acting JIS compact cylinder with a 32mm bore and 40mm full stroke. An external threaded stop with a lock nut permits on-machine extend end-position tuning without swapping parts. You can shorten the extend stroke by up to 10mm, yielding a usable extend range of 30-40mm. The retract stroke remains completely unaffected.
Because the piston area stays constant, output force is identical to a standard ACQ of this size, delivering 402.1N push at 0.5MPa. The unit relies on a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion. Equipped with a -S piston magnet, the cylinder operates seamlessly with both reed and electronic solid-state sensors via its integrated mounting grooves.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 40 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 |

| 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 ACQJ32X40-10S Is Used
Fixture Setup Variation
Dial in the exact 30-40mm extend position for multi-profile machining fixtures without machining new spacers.
Product Changeover Stops
Rapidly reposition the end stop on a packaging line when switching between different carton sizes.
Trial End Positions
Fine-tune the clamping depth on test assemblies to find the optimal stroke before finalizing a rigid setup.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X40-10S the Right Cylinder?
When sizing this 32mm bore actuator, stepping down to a 25mm bore drops the 0.5MPa push force to 245.4N, while moving up to a 40mm bore raises it to 628.3N. If your machinery never requires end-position shifts, a fixed-stroke ACQ32X40 will suffice and saves complexity. To order this adjustable unit correctly, confirm the 32mm bore, 40mm full stroke, 10mm 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 ACQJ32X40-10S FAQ
This 32mm bore cylinder has a 40mm full stroke with a 10mm adjustable window, giving a usable extend range of 30-40mm. It generates 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 external M12x1.25 threaded stop limits how far the rod extends, shortening the stroke length only. It does not change the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for deceleration, and the -S magnet works with reed or solid-state switches.
