Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-75S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-75S 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 ACQJ32X175-75S
The AirTAC ACQJ32X175-75S is a double-acting JIS compact cylinder built for long-stroke, made-to-order applications requiring precise extend positioning. It features a 32mm bore and a 175mm stroke, yielding a usable extend range of 100 to 175mm via an external M12x1.25 stopper. The retract distance remains fixed. Because the piston area is unchanged, output force is identical to a standard ACQ.
This long-stroke variant exceeds the 100mm standard maximum for this bore size. It includes a built-in piston magnet (-S) compatible with reed or solid-state electronic switches, and relies on a fixed NBR elastomer bumper at each end for deceleration. Operating pressure spans 0.15 to 1.0 MPa.

| 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 ACQJ32X175-75S Is Used
Machining Fixture Stops
Dial in the extend endpoint on machining fixtures from 100 to 175mm during setup, allowing rapid accommodation of varying raw material lengths without swapping cylinders.
Assembly Line Changeover
Modify the extended product rejection gate position on packaging lines for different carton sizes by turning the external M12x1.25 threaded stopper directly on the machine.
Prototype Positioning
Establish optimal end-of-stroke locations for automated test probes by testing multiple extend distances within the 75mm window before finalizing a fixed-stroke design.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-75S the Right Cylinder?
For 0.5 MPa pneumatic setups, this 32mm bore yields 402.1 N of push force and 301.6 N of pull force. If your layout requires less thrust, the 25mm bore provides 245.4 N push; if you need more power, the 40mm bore delivers 628.3 N push. A fixed-stroke ACQ is sufficient if your extend endpoint never varies. When ordering, confirm the 175mm full stroke, the 75mm adjustment window, the -S magnet, 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 ACQJ32X175-75S FAQ
The cylinder provides 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The full stroke is 175mm with a 75mm adjustment window, creating a usable extend range of 100 to 175mm. Retract stroke is unaffected.
An external M12x1.25 threaded stop with a lock nut limits the extend distance, changing only the stroke length while keeping output force identical to a standard ACQ. Deceleration is handled by a fixed NBR elastomer bumper at each end, not an adjustable air cushion. The -S magnet works with reed or electronic solid-state switches.
