Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-40
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-40 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 150mm 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 ACQJ40X150-40
The ACQJ40X150-40 is a double-acting JIS compact cylinder featuring an external M12x1.25 threaded stop with a lock nut. This mechanism limits the extend end position, providing a usable forward range of 110 to 150 mm. The retract stroke remains completely unaffected. Because the piston area stays constant, output force matches a standard ACQ exactly.
This configuration is a made-to-order long-stroke variant, exceeding the 100 mm standard maximum for this bore. It features a 16 mm rod, a PT1/8 port, and a female M8x1.25 rod-end thread. Deceleration relies on fixed NBR elastomer bumpers at both ends, while the body retains sensor grooves for adding reed or solid-state switches, though this specific unit ships without a magnet.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Full stroke | 150 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 (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 ACQJ40X150-40 Is Used
Machining Fixture Stops
Dial in the exact clamping extension on CNC machining fixtures without swapping out components during short-run product changeovers.
Variable Carton Forming
Adapt the tucking arm end position on packaging lines to accommodate varying corrugated box heights directly on the machine floor.
Assembly Press Proving
Establish trial end positions for pressing operations on automated assembly lines, safely testing engagement depth before finalizing the setup.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-40 the Right Cylinder?
Selecting this 40 mm bore actuator yields a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. If your application requires less thrust, the 32 mm bore delivers 402.1 N of push force. If you need more power, the 50 mm bore provides 981.8 N. A standard fixed-stroke ACQ is sufficient if your end position never varies. When ordering, confirm the 150 mm full stroke, the 40 mm adjuster window, the female rod thread, and whether you require the S magnet option.
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 ACQJ40X150-40 FAQ
This 40 mm bore cylinder delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa, 879.6 N of push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. The full stroke is 150 mm, and with the 40 mm adjustment window, the usable extend range is 110 to 150 mm.
An external M12x1.25 threaded stop with a lock nut mechanically limits the forward travel, shortening the stroke without changing the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed NBR bumpers for end-of-stroke deceleration and does not hold loads on air loss; for fail-safe load holding, install an external rod lock or pilot-operated check valve.
