Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-10
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-10 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm 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 ACQJ40X175-10
The ACQJ40X175-10 is a double-acting JIS compact cylinder featuring an external M12x1.25 threaded stop and lock nut that limits the extend end position. You get a usable forward travel range of 165 to 175 mm, while the retract stroke remains completely unaffected. Because the piston area stays the same, output force is identical to a standard ACQ of this bore.
This variant is a made-to-order long-stroke unit, exceeding the 100 mm standard maximum for a 40 mm bore. It pushes 628.3 N and pulls 527.8 N at 0.5 MPa, operating via a PT1/8 port. The body includes fixed elastomer bumpers for end-of-stroke deceleration and retains magnetic-switch grooves, though this specific configuration ships without a magnet.

| Bore size | Ø40 mm |
| Full stroke | 175 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 (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 ACQJ40X175-10 Is Used
CNC Tooling Changeovers
Dial in the exact 165 to 175 mm extend position on a CNC lathe when swapping bar pullers or material stops, avoiding the need to machine custom spacer blocks.
Variable Carton Sealing
Adjust the forward stroke on the fly for different box depths on a packaging line, ensuring the sealing head meets the flap without crushing the container.
Assembly Fixture Tuning
Set trial end positions during initial machine commissioning to locate the precise pressing depth for bearing insertion before locking down the stop nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-10 the Right Cylinder?
If 879.6 N of push at 0.7 MPa is excessive, stepping down to a 32 mm bore yields 562.9 N, whereas a 50 mm bore provides 1374.4 N if your fixture demands greater thrust. A fixed-stroke ACQ is sufficient when your end position never varies, but choosing this adjustable unit avoids machining new parts during product changeovers. Confirm your ordering essentials: 40 mm bore, 175 mm full stroke, 10 mm window, female M8x1.25 rod end, and whether you require the -S magnet option for sensing.
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 ACQJ40X175-10 FAQ
This cylinder delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa, with a maximum push of 128 kgf at 1.0 MPa. The full stroke is 175 mm, but the external stop provides a 10 mm adjustment window, giving a usable extend range of 165 to 175 mm.
No, the external stop only changes the extend length, so the force remains identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers at both ends, not an adjustable air cushion. Note that a plain ACQ does not hold its load on air loss, so an external rod lock or pilot-operated check valve is recommended for fail-safe holding.
