Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-40S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-40S 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 ACQJ40X150-40S
The ACQJ40X150-40S is a double-acting JIS compact cylinder with a 40mm bore and a 150mm full stroke. An external threaded stopper with a lock nut permits on-the-fly extend end-position tuning, yielding a usable forward travel range of 110 to 150mm. The retract movement remains fixed at its standard length. Because the piston area is unaltered, output force equals that of a conventional ACQ unit.
This unit includes a built-in piston magnet (-S) compatible with reed or solid-state switches. It features a 16mm rod, an M8x1.25 female rod-end thread, and PT1/8 ports. A fixed NBR elastomer bumper decelerates motion at both extremes. Since 150mm exceeds the 100mm standard maximum, this is a long-stroke made-to-order variant.

| 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 ACQJ40X150-40S Is Used
Product Changeover Stops
Adjust the external stopper to quickly set new forward positions during packaging line format changes without machining new spacers.
Prototype Stroke Tuning
Dial in the exact 110-150mm forward travel during R&D testing on a custom assembly rig before finalizing fixed dimensions.
Variable Depth Forming
Regulate the extension depth on a light-duty press to accommodate material thickness variations while maintaining 879.6N output at 0.7MPa.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X150-40S the Right Cylinder?
For sizing context, dropping to a 32mm bore yields 402.1N push at 0.5MPa, while stepping up to a 50mm bore provides 981.8N. Choose this 40mm option when your mechanism needs 628.3N push (527.8N pull at 0.5MPa) alongside adaptable positioning. If your equipment never requires end-point shifting, a fixed-stroke ACQ will suffice. To order, confirm the 40mm bore, 150mm full stroke, 40mm adjuster window, the -S magnet, and the M8x1.25 female 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 ACQJ40X150-40S FAQ
It delivers 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 full stroke is 150mm, with a 40mm window allowing an adjustable extend range of 110-150mm; retract is unaffected.
The M12x1.25 external threaded stop with lock nut limits forward travel length only, leaving output force unchanged. Deceleration relies on a fixed NBR elastomer bumper at each end. Note that a plain ACQ cylinder will drift on air loss; for fail-safe holding, add an external rod lock.
