Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-20B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-20B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 35mm 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 ACQJ32X35-20B
The AirTAC ACQJ32X35-20B is a double-acting JIS compact cylinder featuring an external threaded stop and lock nut that restricts the extend stroke. You can fine-tune the extend end position on the machine, yielding a usable extend range of 15-35 mm (the 35 mm full stroke minus up to a 20 mm window). The retract stroke remains completely unaffected.
Because the adjuster only alters travel length and not piston area, force output is identical to a standard ACQ of the same bore. This configuration includes a male M14x1.5 rod-end thread for direct load coupling, a 16 mm piston rod, and PT1/8 ports. The body incorporates fixed elastomer bumpers at both ends rather than adjustable air cushions, and ships without a magnet while retaining sensor grooves.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 35 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 ACQJ32X35-20B Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC fixture during product changeover without machining new stop collars or swapping cylinders.
Carton Folding Arms
Adjust the folding stroke on the fly for different box depths, ensuring precise flap closure without taking the packaging line offline.
Assembly Press Tonnage
Set trial end positions for a light-duty assembly press, tweaking the 15-35 mm extend range to accommodate varying component heights.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-20B the Right Cylinder?
For a 32 mm bore, this cylinder delivers 402.1 N of push force and 301.6 N of pull force at 0.5 MPa. If your application requires less force, dropping to a 25 mm bore yields 245.4 N push, whereas stepping up to a 40 mm bore provides 628.3 N push. Choose this adjustable version if your fixture setup or product changeover requires variable extend end stops; otherwise, a fixed-stroke ACQ is simpler. Confirm ordering essentials: 32 mm bore, 35 mm full stroke, 20 mm window, male M14x1.5 rod thread, and no magnet.
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 ACQJ32X35-20B FAQ
At 0.5 MPa, push force is 402.1 N and pull force is 301.6 N. At 0.7 MPa, push force is 562.9 N, with a maximum push of 82 kgf at 1.0 MPa. The usable extend range is 15-35 mm (the 35 mm full stroke minus up to a 20 mm adjustment window).
An external M12x1.25 threaded stop with a lock nut limits how far the rod extends, shortening the stroke length without changing piston area, so force remains identical to a standard ACQ. The retract stroke is unaffected. Deceleration relies on fixed elastomer bumpers at each end, not adjustable air cushions, so external shock absorbers are recommended for high-energy loads.
