Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-100S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-100S 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 ACQJ32X175-100S
The AirTAC ACQJ32X175-100S is a double-acting, single-rod JIS compact cylinder with an external extend-stop mechanism. It features a 32mm bore and a 175mm total stroke, but the threaded adjuster with lock nut lets you set the extend end-position anywhere within a 75 to 175mm usable range. The retract stroke remains completely unaffected. Because the piston area is unchanged, output force is identical to a standard ACQ of this size.
This long-stroke variant exceeds the 100mm standard maximum for Ø32 bores, making it a made-to-order solution for applications needing extended reach. It includes a built-in magnet (-S) for position sensing with reed or electronic solid-state switches. The body uses a compact C-clip design with a fixed NBR elastomer bumper at each end for end-of-stroke deceleration, rather than an adjustable air cushion.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-100S |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 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 |
| Temperature | -20 to +70 °C |
| 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 ACQJ32X175-100S Is Used
Varying Fixture Setups
Dial in the extend stop for different jig heights on a machining center without machining new spacers or swapping cylinders.
Product Changeover Stops
Quickly reposition the end-of-stroke limit for new packaging carton sizes on a conveyor line, saving changeover time.
Trial End Positions
Fine-tune the extension distance during equipment prototyping to find the exact clamping point before locking the nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-100S the Right Cylinder?
Choosing this 32mm bore provides 402.1N push and 301.6N pull force at 0.5 MPa. If your application requires less force, stepping down to a 25mm bore yields 245.4N push, while moving up to a 40mm bore provides 628.3N push. A standard fixed-stroke ACQ is sufficient if you do not require on-machine end-position tuning. When ordering, confirm the 32mm bore, 175mm full stroke, 100mm adjustment window, the -S magnet option, and the default female M8x1.25 rod-end 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 ACQJ32X175-100S FAQ
This model delivers 402.1N push and 301.6N pull at 0.5 MPa, 562.9N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The full stroke is 175mm with a 100mm adjustment window, yielding a usable extend range of 75-175mm.
No, the external M12x1.25 threaded stop only limits how far the rod extends, shortening the extend stroke without changing the piston area or force. The retract stroke is unaffected. Deceleration is handled by a fixed elastomer bumper, not an adjustable air cushion.
