Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-100
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-100 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 ACQJ40X175-100
The ACQJ40X175-100 is a double-acting, single-rod JIS compact cylinder featuring a 175 mm stroke and a 40 mm bore. An external threaded stop with a lock nut limits the extend end position, providing an adjustable usable extend range of 75 to 175 mm. Retract travel remains fixed at the full 175 mm. Because the piston area is unchanged, force output is identical to a standard ACQ of this size.
This configuration is a made-to-order long-stroke variant, as the 175 mm length exceeds the 100 mm standard maximum for this bore. It delivers 628.3 N of push force at 0.5 MPa and uses a PT1/8 port. The body incorporates fixed elastomer bumpers at both ends rather than adjustable air cushions, and ships without a magnet while retaining sensor grooves for future upgrades.

| 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 ACQJ40X175-100 Is Used
Multi-Variant Machining Fixtures
Dial in the extend stop from 75 to 175 mm during product changeovers on a CNC lathe, accommodating different part lengths without machining custom spacer blocks.
Adjustable Carton Sealing Jaws
Tune the extend end position on a packaging line to handle varying box heights, using the external M12x1.25 stopper nut to set the exact sealing depth.
Long-Reach Part Ejectors
Utilize the 175 mm travel to push finished components out of large press dies, adjusting the final ejection point on the machine without replacing the cylinder.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X175-100 the Right Cylinder?
When sizing this unit, consider the ACQJ32X100-100 for a smaller footprint, yielding 402.1 N push at 0.5 MPa, or the ACQJ50X100-100 for heavier loads, providing 981.8 N push at 0.5 MPa. If your extend end position never varies, a fixed-stroke ACQ40X175 will suffice and eliminates the external adjuster hardware. To order correctly, confirm the 40 mm bore, 175 mm full stroke, 100 mm adjuster window, female M8x1.25 rod end thread, and that no magnet (-S) is required.
Quick checklist

- ✓ 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 ACQJ40X175-100 FAQ
At 0.5 MPa, the push force is 628.3 N and the pull force is 527.8 N. At 0.7 MPa, the push force is 879.6 N, with a maximum push of 128 kgf at 1.0 MPa. The full stroke is 175 mm, and the 100 mm adjustable window allows the usable extend range to be set anywhere from 75 to 175 mm. The external adjuster thread is M12x1.25.
The external threaded stop physically blocks the rod from extending further, shortening the stroke length without altering the piston area, so the force remains identical to a standard ACQ. The retract stroke is unaffected. Deceleration is handled by fixed NBR elastomer bumpers at both ends, not adjustable air cushions, so external shock absorbers are recommended for high-speed loads.
