Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-75
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-75 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 175mm 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 ACQJ32X175-75
The ACQJ32X175-75 is a double-acting JIS compact cylinder with a 32mm bore and a 175mm made-to-order long stroke, exceeding the standard 100mm maximum for this bore size. It uses an external M12x1.25 threaded stop with a lock nut on the rod-end side to restrict how far the rod extends. You can shorten the extend stroke by up to 75mm, yielding a usable extend range of 100-175mm, while the retract stroke remains unaffected.
Because the piston area is unchanged, the output force is identical to a standard ACQ of the same bore, delivering 402.1N push and 301.6N pull at 0.5MPa. The body features integrated magnetic-switch grooves, though this specific SKU ships without the -S magnet. Deceleration is handled by fixed NBR elastomer bumpers at both ends rather than adjustable air cushions.

| 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 ACQJ32X175-75 Is Used
Machining Fixture Stops
Dial in the exact extend position of clamping arms on a CNC machining fixture during new product setup without machining custom spacers.
Packaging Changeover
Adjust the extend pusher length on a packaging line to accommodate different carton sizes rapidly during product changeover.
Prototype Press Testing
Find the optimal end-of-stroke pressing position on a prototype assembly press by tweaking the external stop nut between 100 and 175mm.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-75 the Right Cylinder?
This 32mm bore provides 562.9N of push force at 0.7MPa. If you need less force, consider the 25mm bore (245.4N push @0.5MPa), or step up to the 40mm bore (628.3N push @0.5MPa) for higher load capacity. A standard fixed-stroke ACQ cylinder is sufficient if your end position never requires on-machine adjustment. When ordering, confirm the 175mm full stroke, the 75mm adjustable window, the female M8x1.25 rod-end thread, and the PT1/8 port size.
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 ACQJ32X175-75 FAQ
It delivers 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82kgf at 1.0MPa. The full stroke is 175mm with a 75mm adjustable window, giving a usable extend range of 100-175mm. The bore is 32mm, the port is PT1/8, the female rod-end thread is M8x1.25, and the external adjuster thread is M12x1.25.
No, the external stop limits the extend stroke length only, so the force remains identical to a standard ACQ. The cylinder uses fixed NBR elastomer bumpers at both ends for deceleration instead of adjustable air cushions. Note that a plain cylinder like this does not hold its load on air loss; for a fail-safe hold, use an external rod lock or pilot-operated check valve.
