Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-100B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-100B 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 ACQJ32X175-100B
The ACQJ32X175-100B is a double-acting JIS compact cylinder with a 32mm bore and a 175mm total stroke. As a long-stroke made-to-order variant, it surpasses the 100mm standard maximum for this bore size while retaining the C-clip riveted body design. It includes a male M14x1.5 piston rod end for direct load coupling and a PT1/8 port.
A 100mm adjustable window lets you fine-tune the extend end position on the machine, yielding a usable extend range of 75-175mm. An external M12x1.25 threaded stop with a lock nut handles this restriction, while the retract stroke remains unaffected. Because the piston area stays constant, output force is identical to a standard ACQ: 402.1N push and 301.6N pull at 0.5MPa. Fixed NBR elastomer bumpers decelerate the motion at both ends.

| 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 ACQJ32X175-100B Is Used
Machining Fixture Stops
Dial in the extend travel from 75 to 175mm directly on the machining center to accommodate varying raw casting lengths without printing new fixture plates.
Product Changeover Diverter
Shift the extend end position on a packaging conveyor diverter gate during a product family changeover, locking the M12x1.25 stop nut firmly at the new reject distance.
Prototype Press End-Stop
Sweep through multiple extend end positions on a lab press to find the exact 75-175mm travel needed for a new forming process before finalizing the mechanical design.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-100B the Right Cylinder?
If you need less push power, the 25mm bore yields 245.4N push at 0.5MPa, whereas stepping up to the 40mm bore provides 628.3N. If the exact 175mm travel is not required, a fixed-stroke ACQ suffices and avoids the made-to-order lead time. When ordering this unit, verify the 32mm bore, 175mm full stroke, 100mm window, the male M14x1.5 rod thread, and confirm no magnet is installed.
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 ACQJ32X175-100B 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 175mm full stroke is a long-stroke made-to-order variant. The external stop provides a 100mm window, so the usable extend range is 75-175mm.
The external M12x1.25 threaded stop only limits extend travel; it does not alter piston area, so force matches a standard ACQ. Retract travel is unaffected. Deceleration relies on fixed NBR elastomer bumpers at each end, not adjustable air cushions. This unit ships without a sensor magnet.
