Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X30-30
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X30-30 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 ACQJ32X30-30
The AirTAC ACQJ32X30-30 is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. With a full stroke of 30mm and a 30mm adjustment window, the usable extend range runs from 0 to 30mm. The retract stroke remains completely unaffected by this mechanism. Because the piston area stays the same, the output force is identical to a standard ACQ of this bore.
This 32mm bore model delivers 402.1N of push force and 301.6N of pull force at 0.5MPa. It features a 16mm piston rod, PT1/8 porting, and an M12x1.25 adjuster thread. The body includes fixed elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. Sensor grooves are integrated into the body, though this specific configuration ships without a magnet.

| 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 ACQJ32X30-30 Is Used
Machining Fixture Stops
Dial in the exact extend position for varying raw material thicknesses on a CNC lathe loading station without machining custom spacer plates.
Carton Changeover Guides
Quickly reposition the extend end stop to accommodate different box sizes on a packaging line during rapid product format changeovers.
Prototype Positioning
Establish optimal end positions during robotic assembly trials by adjusting the external stop nut instead of reprogramming motion controllers.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X30-30 the Right Cylinder?
If your application requires less force, stepping down to a 25mm bore yields a 245.4N push at 0.5MPa. If you need more power, moving up to a 40mm bore provides 628.3N of push force at 0.5MPa. A fixed-stroke ACQ cylinder is sufficient if your end position never needs alteration. When ordering, verify the 32mm bore, 30mm full stroke, 30mm window, female M8x1.25 rod thread, and whether you require the -S magnet option for switch sensing.
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 ACQJ32X30-30 FAQ
The usable extend range is 0-30mm (a 30mm full stroke minus a 30mm window). The force is identical to a standard ACQ: 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.
An external M12x1.25 threaded stop with a lock nut limits the extend length without altering the piston area, so force remains unchanged. The retract stroke is unaffected. Fixed elastomer bumpers handle deceleration at both ends. The body has sensor grooves, but this model ships without a magnet.
