Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-30S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-30S 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 ACQJ32X175-30S
The ACQJ32X175-30S is a double-acting, single-rod JIS compact cylinder with a 32mm bore and a 175mm full stroke. An external M12x1.25 threaded stop and lock nut lets you fine-tune the extend end position on the machine, providing a usable extend range of 145 to 175mm. The retract stroke remains completely unaffected by this adjustment. Because the piston area is unchanged, the output force is identical to a standard ACQ of this bore. This unit includes a built-in piston magnet (-S) for position sensing.
As a long-stroke made-to-order variant, it exceeds the 100mm standard maximum for this bore while retaining the fixed NBR elastomer bumpers at each end for end-of-travel deceleration. Operating pressure is 0.15-1.0 MPa, and the body features integrated magnetic-switch grooves compatible with reed or electronic solid-state sensors. The standard port is PT1/8, and the default rod end features an M8x1.25 female thread.

| 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 ACQJ32X175-30S Is Used
Machining Fixture Stops
Dial in the exact extend position of clamping arms on a CNC machining center during setup changes without machining new stop collars.
Product Changeover Diverters
Adjust the extend stroke of a sorting gate on a packaging conveyor line to accommodate varying carton lengths on the fly.
Bending Press Trial Positions
Set trial end positions for a metal forming or bending press, allowing operators to test bend depths incrementally before locking the nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-30S the Right Cylinder?
When sizing this cylinder, note it delivers 402.1N push and 301.6N pull at 0.5 MPa. If your application requires less force, stepping down to a 25mm bore yields 245.4N push, whereas stepping up to a 40mm bore provides 628.3N push. A fixed-stroke standard ACQ32 is sufficient if your extend end position never requires on-the-fly tuning. Confirm your ordering essentials: 32mm bore, 175mm full stroke, -30mm adjustable window, -S magnet option, 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 ACQJ32X175-30S FAQ
The push force is 402.1N at 0.5 MPa (562.9N at 0.7 MPa) and pull is 301.6N at 0.5 MPa, with a maximum push capacity of 82 kgf at 1.0 MPa. The usable extend range is 145-175mm, achieved by shortening the 175mm full stroke by up to 30mm. The adjuster changes stroke length only, so force is identical to a standard ACQ.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke, while the retract stroke is unaffected. The cylinder uses fixed NBR elastomer bumpers at each end, not adjustable air cushions. A plain ACQ-type does not hold its load on air loss or when a valve is centered, so an external rod lock or pilot-operated check valve is required for fail-safe load holding.
