Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X10-10SBH
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X10-10SBH is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 10mm 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 ACQJ40X10-10SBH
The ACQJ40X10-10SBH is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. With a full stroke of 10mm and an adjustment window of 10mm, you can fine-tune the usable extend range from 0mm up to 10mm directly on the machine without changing parts. The retract stroke remains completely unaffected by this mechanism.
Because the piston area is unchanged, the force output is identical to a standard ACQ of the same bore, delivering 628.3N push and 527.8N pull at 0.5MPa. This unit includes a built-in piston magnet for position sensing and a male M14x1.5 piston rod end that couples directly to your load. It uses a PT1/8 port and relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration.

| Port size | PT1/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 ACQJ40X10-10SBH Is Used
Fixture Position Tuning
Dial in the exact clamping reach from 0 to 10mm during initial fixture setup on a machining center to accommodate varying part tolerances.
Product Changeover Stops
Quickly reposition the extend end stop on a packaging line when switching between different carton sizes, minimizing changeover downtime.
Trial End Positions
Test different pressing depths on a small assembly press without fabricating new spacers, allowing rapid iteration during process development.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X10-10SBH the Right Cylinder?
If you need slightly less thrust, the 32mm bore variant provides 402.1N push at 0.5MPa, whereas stepping up to the 50mm bore yields 981.8N push. For applications where the end position never varies, a fixed-stroke ACQ cylinder is sufficient. To order this adjustable model correctly, confirm the 40mm bore, 10mm full stroke, 10mm adjustment window, the S magnet option, and the B male rod 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 ACQJ40X10-10SBH FAQ
It provides 628.3N push and 527.8N pull at 0.5MPa, 879.6N push at 0.7MPa, and a maximum push of 128kgf at 1.0MPa. The usable extend range is 0-10mm, set by subtracting the 10mm window from the 10mm full stroke.
An external M12x1.25 threaded stop with a lock nut limits the extend distance without altering the piston area, so force remains identical to a standard ACQ. Deceleration relies on a fixed elastomer bumper, not an adjustable air cushion; the cylinder will not hold its load on air loss, so an external rod lock is needed for fail-safe holding.
