Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-30S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-30S 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 ACQJ32X35-30S
The AirTAC ACQJ32X35-30S is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. With a full stroke of 35mm and a 30mm adjustment window, you can fine-tune the usable extend range from 5mm up to 35mm directly on the machine. The retract stroke remains completely unaffected by this mechanism.
Because the piston area is unchanged, force output is identical to a standard ACQ of the same bore, delivering 402.1N push at 0.5 MPa. The cylinder body uses a compact C-clip and riveted construction with a fixed NBR elastomer bumper at each end. This specific model includes the -S magnet option, meaning its built-in piston magnet is fully compatible with both reed and electronic solid-state switches.

| 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 |

| 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 ACQJ32X35-30S Is Used
Machining Fixture Stops
Dial in the exact 5-35mm extend position for part clamps during CNC setup changes without fabricating new mechanical spacers.
Carton Forming Turrets
Adjust the pusher end stop on the fly to handle varying package depths on a packaging line without swapping out the cylinder.
Laboratory Test Rigs
Set precise extend endpoints for repetitive material testing, relying on the fixed elastomer bumper to absorb impact at high speeds.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X35-30S the Right Cylinder?
If you need slightly less force, the ACQJ25 model offers 245.4N push @0.5 MPa, while stepping up to the ACQJ40 bore provides 628.3N push @0.5 MPa for heavier loads. A fixed-stroke ACQ cylinder is sufficient if your extend end position never requires future adjustment. When ordering this unit, confirm the 32mm bore, 35mm full stroke, 30mm 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 ACQJ32X35-30S FAQ
The force is identical to a standard ACQ32, providing 402.1N push and 301.6N pull @0.5 MPa, 562.9N push @0.7 MPa, and a maximum push of 82 kgf @1.0 MPa. The usable extend range is 5-35mm (35mm full stroke minus the 30mm window).
An external M12x1.25 threaded stop with a lock nut limits the extend length, changing only the stroke distance without reducing piston force. The retract stroke is unaffected. Note that a plain ACQ-type cylinder does not hold its load on air loss; use an external rod lock or pilot-operated check valve for fail-safe holding.
