Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-40
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-40 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 ACQJ32X175-40
The ACQJ32X175-40 is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. You can fine-tune the usable extend travel on the machine across a 135-175 mm range, shortening the 175 mm full stroke by up to 40 mm without changing parts. The retract stroke remains completely unaffected. Because the piston area stays the same, the output force is identical to a standard ACQ of this bore, delivering 402.1 N push and 301.6 N pull at 0.5 MPa.
This made-to-order long-stroke variant exceeds the 100 mm standard maximum for the 32 mm bore, reaching up to the 300 mm extended range. It features a 16 mm piston rod, PT1/8 porting, and a female M8x1.25 rod-end thread. The body incorporates fixed NBR elastomer bumpers at each end for deceleration rather than adjustable air cushions. While this specific unit ships without a magnet, the cylinder body retains magnetic-switch grooves for adding reed or solid-state sensors if needed later.

| 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 ACQJ32X175-40 Is Used
Product Changeover Stops
Dial in the extend end position across the 135-175 mm window during packaging line format changes without machining new spacers or swapping cylinders.
Press Stroke Setup
Set precise clamping depth on a light assembly press using the external M12x1.25 adjuster, relying on the fixed elastomer bumper to absorb the end-of-stroke impact.
Trial End Positions
Establish the exact extension point for a testing fixture by turning the threaded stop, safely testing various engagement lengths before locking the nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-40 the Right Cylinder?
When sizing this 32 mm bore actuator, stepping down to a 25 mm bore yields 245.4 N push at 0.5 MPa, whereas stepping up to a 40 mm bore provides 628.3 N. If your application requires a fixed end position every cycle and no on-machine adjustability, a standard ACQ cylinder will suffice. For ordering, confirm the 32 mm bore, 175 mm full stroke, 40 mm adjuster window, female M8x1.25 rod thread, and PT1/8 porting. Note that this is a long-stroke variant exceeding the 100 mm standard maximum for this bore.
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 ACQJ32X175-40 FAQ
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 usable extend range is 135-175 mm (a 40 mm window off the 175 mm full stroke). The piston rod is 16 mm, the port is PT1/8, and the external adjuster thread is M12x1.25.
No, the external stop alters only the extend stroke length, not the piston area, so force remains identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers at each end rather than adjustable air cushions. Note that a plain compact cylinder will not hold its load on air loss; for fail-safe holding, use an external rod lock or pilot-operated check valve.
