Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-10B 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 ACQJ40X150-10B
The ACQJ40X150-10B is a double-acting JIS compact cylinder with an external extend stop. A threaded adjuster and lock nut let you fine-tune the extend end position on the machine, yielding a usable extend range of 140-150mm from the 150mm full stroke. Retract travel remains unaffected. This long-stroke variant exceeds the standard 100mm maximum for this bore.
Because the piston area is unchanged, output force is identical to a standard ACQ: 628.3N push and 527.8N pull at 0.5MPa. It features a male M14x1.5 rod end for direct coupling. The body includes sensor grooves, though this specific unit ships without a magnet. Fixed NBR elastomer bumpers decelerate the piston at each end.

| 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 |
| 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 (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 ACQJ40X150-10B Is Used
Machining Fixture Clamping
Dial in the exact clamping reach on a CNC fixture without machining new spacers, accommodating raw part variations instantly.
Carton Flap Folding
Adjust the extend stop to set flap folding depth for different box sizes on a packaging line during product changeover.
Assembly Press Positioning
Set precise trial end positions for pressing bearings on an assembly line, tweaking the 140-150mm window until force alignment is perfect.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-10B the Right Cylinder?
Comparing neighbours: the smaller bore 32 yields 402.1N push, while the larger bore 50 provides 981.8N push at 0.5MPa. Choose this 40mm bore if you need roughly 628N of push force. If the end position never varies, a fixed-stroke ACQ cylinder is simpler. When ordering, confirm the 150mm full stroke, the 10mm adjuster window, the male M14x1.5 rod thread, and whether you require the S magnet option for sensing.
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 ACQJ40X150-10B FAQ
The usable extend range is 140-150mm. Force is identical to a standard ACQ: 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 bore is 40mm with a PT1/8 port.
The external M12x1.25 threaded stop limits how far the rod extends, shortening stroke length only; piston area and force remain unchanged. Fixed NBR bumpers decelerate movement at the ends. Note that a plain ACQ cylinder will drift on air loss, so add an external rod lock for fail-safe load holding.
