Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-40
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-40 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm 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 ACQJ32X150-40
The ACQJ32X150-40 is a double-acting JIS compact cylinder built for applications requiring precise extend-position tuning. It features an external threaded stop with a lock nut on the rod-end side, allowing you to shorten the extend stroke by up to 40 mm. This yields a usable extend range of 110 to 150 mm, while the retract stroke remains completely unaffected. Because the piston area is unchanged, the force output is identical to a standard ACQ of the same bore.
This specific configuration is a long-stroke, made-to-order variant, as the 150 mm stroke exceeds the 100 mm standard maximum for a 32 mm bore. It pushes 402.1 N and pulls 301.6 N at 0.5 MPa, with a 562.9 N push force at 0.7 MPa. The unit incorporates a fixed NBR elastomer bumper at each end for end-of-stroke deceleration and includes sensor grooves, though this particular SKU ships without a piston magnet.

| Bore size | Ø32 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 (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 ACQJ32X150-40 Is Used
Machining Fixture Setup
Dial in the exact clamping extension on a CNC fixture during prototype runs without machining new stop collars or swapping cylinders.
Product Changeover Stops
Adjust the physical extend stop position on a packaging line diverter when switching between different carton widths.
Assembly Press Trials
Fine-tune the pressing depth on an electronic component insertion press to find the optimal end position before locking the nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-40 the Right Cylinder?
When sizing this unit, consider the adjacent bores: a 25 mm bore yields 245.4 N push at 0.5 MPa, while a 40 mm bore provides 628.3 N. If your extend position never varies, a fixed-stroke ACQ32x150 cylinder suffices and avoids the external adjuster overhang. For this adjustable model, verify your ordering essentials: 32 mm bore, 150 mm full stroke, 40 mm window, female M8x1.25 rod-end thread, and PT1/8 port. Note that a plain ACQ-type cylinder does not hold its load on air loss; for fail-safe holding, specify an external rod lock or pilot-operated check valve.
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 ACQJ32X150-40 FAQ
The usable extend range is 110-150 mm (150 mm full stroke minus the 40 mm window). It delivers 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The port is PT1/8 and the external adjuster thread is M12x1.25.
No, the adjuster only limits how far the rod extends, leaving the piston area and force output identical to a standard ACQ. The cylinder uses a fixed NBR elastomer bumper at each end for deceleration rather than an adjustable air cushion. This model lacks a piston magnet, but the body retains sensor grooves for adding reed or solid-state switches if needed.
