Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-40
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-40 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 100mm 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 ACQJ32X100-40
The AirTAC ACQJ32X100-40 is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend range from 60 to 100 mm directly on the machine without swapping parts, while the retract stroke remains unaffected.
Because the piston area stays the same, the force is identical to a standard ACQ of this bore, delivering a push of 402.1 N at 0.5 MPa. The unit features a 16 mm rod, PT1/8 port, and fixed elastomer bumpers at both ends for compact depth. It ships without a magnet, though the body retains sensor grooves for later upgrades.

| 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 ACQJ32X100-40 Is Used
Machining Fixture Stops
Dial in the extend position from 60 to 100 mm to accommodate varying raw material lengths on a milling fixture without machining new stop collars.
Assembly Line Changeover
Quickly reposition the extend end point during product family changeovers on an automated assembly line, saving setup time.
Carton Forming Trials
Test different folding depths on a packaging machine by adjusting the extend stroke in the 40 mm window until the ideal fold is found.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-40 the Right Cylinder?
If you need slightly less force, the 25 mm bore provides a 245.4 N push at 0.5 MPa, whereas stepping up to the 40 mm bore yields a 628.3 N push. A fixed-stroke ACQ32X100 is sufficient if your extend end position never requires adjustment. When ordering this adjustable version, confirm the 32 mm bore, 100 mm full stroke, 40 mm window, female M8x1.25 rod thread, and that no magnet (-S) is needed.
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 ACQJ32X100-40 FAQ
The usable extend range is 60-100 mm (100 mm full stroke minus the 40 mm window). Force equals a standard ACQ: push is 402.1 N and pull is 301.6 N at 0.5 MPa, push is 562.9 N at 0.7 MPa, and max push is 82 kgf at 1.0 MPa.
An M12x1.25 threaded stop with a lock nut limits the extend stroke, changing only the stroke length and not the force. The cylinder uses fixed NBR elastomer bumpers, not adjustable air cushions. This model ships without a magnet, but the body grooves accept reed or solid-state switches if you add one later.
