Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-20
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-20 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 ACQJ32X175-20
The ACQJ32X175-20 is a double-acting JIS compact cylinder featuring a 175mm extended stroke, configured as a made-to-order long-stroke variant beyond the standard 100mm limit for this 32mm bore. An external M12x1.25 threaded stop and lock nut allows you to fine-tune the extend end position on the machine, yielding a usable extend range of 155-175mm. The retract stroke remains completely unaffected by this adjustment.
Because the piston area is unchanged, output force is identical to a standard ACQ of the same size, delivering 402.1N push and 301.6N pull at 0.5MPa. The unit incorporates fixed NBR elastomer bumpers at each end for end-of-stroke deceleration rather than adjustable air cushions. While this specific SKU ships without a magnet, the body retains magnetic-switch grooves for adding sensors if needed later.

| 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 ACQJ32X175-20 Is Used
Machining Fixture Positioning
Dial in the exact clamping extension on a CNC machining center without machining new spacer blocks when part dimensions change.
Assembly Line Changeover
Rapidly reconfigure the extended push-off distance for a product transfer arm during packaging format transitions.
Prototype Stroke Trials
Safely test varying extend end positions on a new automated test rig to find the optimal engagement distance before finalizing the design.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-20 the Right Cylinder?
Choosing this 32mm bore provides 402.1N of push force at 0.5MPa; stepping down to a 25mm bore yields 245.4N, while moving up to a 40mm bore offers 628.3N. A fixed-stroke ACQ is sufficient if your extend endpoint never requires tweaking. When ordering this cylinder, confirm the 175mm full stroke, the 20mm adjustment window, the female M8x1.25 rod-end thread, and the PT1/8 port. Note that because this is a non-standard 175mm stroke, it is manufactured as a long-stroke variant.
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 ACQJ32X175-20 FAQ
This model has a 175mm full stroke with a 20mm adjustable window, allowing the usable extend range to be set between 155mm and 175mm. It delivers 402.1N push and 301.6N pull at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82 kgf at 1.0 MPa. The retract stroke remains fixed at 175mm.
An external M12x1.25 threaded stop with a lock nut limits the extend travel, shortening the stroke without changing the piston area, so force remains identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. For high-speed loads, an external shock absorber is recommended, and a rod lock is needed to hold loads on air loss.
