Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-40S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-40S 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 ACQJ32X175-40S
The ACQJ32X175-40S is a double-acting JIS compact cylinder with a 175mm extended stroke, built as a made-to-order variant since the standard maximum for this 32mm bore is 100mm. It incorporates a 40mm adjustable window, meaning the extend end position can be fine-tuned on the machine anywhere from 135mm up to the full 175mm. The retract stroke remains completely unaffected.
Because the external stop only limits travel length, the piston area stays the same, yielding force identical to a standard ACQ: 402.1N push and 301.6N pull at 0.5MPa. The Ø16mm rod uses an M8x1.25 female end, and the M12x1.25 adjuster thread locks securely with a nut. It includes an -S magnet for electronic or reed switches and relies on fixed NBR elastomer bumpers for end-of-stroke deceleration.

| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| 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 ACQJ32X175-40S Is Used
CNC Tooling Changeover
Dial in the extend stop from 135 to 175mm when swapping machining fixtures on a CNC mill, avoiding the need to fabricate custom spacer plates.
Packaging Format Adjustments
Tune the rod extension on the fly for different carton sizes on a packaging line, using the external stop to set precise pushing distances.
Prototype Positioning
Establish optimal end positions during equipment R&D by testing various extend lengths within the 40mm window before finalizing mechanical hard stops.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X175-40S the Right Cylinder?
If 402.1N push at 0.5MPa is excessive, step down to a 25mm bore (157.1N push); if more power is needed, move up to a 40mm bore (628.3N push). A standard fixed-stroke ACQ suffices if your extend endpoint never varies. When ordering this long-stroke unit, confirm the 175mm travel, 40mm window, PT1/8 port, and the -S magnet requirement. Note that a plain compact cylinder drifts on air loss, so add an external rod lock for fail-safe load holding.
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 ACQJ32X175-40S FAQ
This 32mm bore cylinder has a usable extend range of 135-175mm (175mm full stroke minus the 40mm window). 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 retract stroke remains the full 175mm.
No, the force is identical to a standard ACQ because the external M12x1.25 threaded stop only limits travel length without altering piston area. The cylinder uses fixed NBR elastomer bumpers at both ends for deceleration rather than adjustable air cushions. The built-in -S magnet supports both reed and solid-state electronic switches.
