Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X30-30S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X30-30S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 30mm 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 ACQJ32X30-30S
The AirTAC ACQJ32X30-30S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. You can fine-tune the usable extend range from 0 mm up to the full 30 mm directly on your machinery without swapping parts, while the retract stroke remains completely unaffected. It includes a built-in piston magnet (-S) compatible with both reed and electronic solid-state switches.
Because the adjuster alters stroke length only, the piston area stays the same, meaning force output is identical to a standard ACQ of this bore. At 0.5 MPa, it delivers a push force of 402.1 N and a pull force of 301.6 N. The unit features a 16 mm rod, a PT1/8 port, fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration, and an M12x1.25 external adjuster thread.

| 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 ACQJ32X30-30S Is Used
Fixture Setup Variations
Dial in the extend stop from 0 to 30 mm to accommodate varying workpiece thicknesses during machining fixture changes.
Product Changeover Stops
Rapidly reposition the extend end position for different package sizes on a packaging line without disassembling the cylinder.
Trial End Positions
Test and validate exact clamping depths on new laboratory automation prototypes by adjusting the external stopper nut.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X30-30S the Right Cylinder?
If you need slightly less thrust, the 25 mm bore offers a 245.4 N push at 0.5 MPa, whereas stepping up to a 40 mm bore provides 628.3 N. Choose this 32 mm bore when your application requires roughly 400 N of push force combined with on-the-fly extend length tuning. If the end position never varies, a fixed-stroke ACQ cylinder is sufficient. When ordering, verify the 30 mm full stroke, the 30 mm adjustable 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 ACQJ32X30-30S FAQ
It delivers a push force of 402.1 N and a pull force of 301.6 N at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The usable extend range is 0-30 mm (a 30 mm full stroke minus up to a 30 mm window), and the retract stroke is unaffected.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke, changing the stroke length only. The force remains identical to a standard ACQ because the piston area is unchanged. Deceleration is handled by fixed elastomer bumpers, not an adjustable air cushion.
