Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-40S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-40S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 80mm 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 ACQJ32X80-40S
The AirTAC ACQJ32X80-40S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. With an 80mm full stroke and a 40mm adjustment window, the usable extend range runs from 40mm up to 80mm. The retract stroke remains completely unaffected. Because the piston area is unchanged, the output force is identical to a standard ACQ of the same bore.
Operating pressure is 0.15-1.0 MPa with a fixed NBR elastomer bumper at each end for end-of-stroke deceleration. The -S option includes a built-in piston magnet compatible with reed or solid-state electronic switches via the body's sensor grooves. The Ø16mm rod uses an M8x1.25 female thread, and the external adjuster utilizes an M12x1.25 thread.

| 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 ACQJ32X80-40S Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC machining fixture during setup, allowing rapid accommodation of varying raw part sizes without swapping cylinder hardware.
Packaging Changeover
Rapidly adjust the product push-off end position on a packaging line during format changeovers, using the external M12x1.25 stopper to hit new carton dimensions.
Assembly Press Testing
Fine-tune the trial insertion depth on an electronics assembly press, testing multiple engagement positions on the fly before locking the nut for production runs.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X80-40S the Right Cylinder?
When sizing this 32mm bore actuator, note it delivers 402.1N push and 301.6N pull at 0.5 MPa. If your application requires less force, the next size down (25mm) provides 245.4N push, whereas stepping up to a 40mm bore yields 628.3N push. A fixed-stroke ACQ is sufficient if your extend end position never needs on-machine tweaking. To order, confirm the 32mm bore, 80mm full stroke, 40mm window, the -S magnet, and the default female rod 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 ACQJ32X80-40S FAQ
The usable extend range is 40-80mm (80mm full stroke minus the 40mm window). Force is identical to a standard ACQ: 402.1N push and 301.6N pull at 0.5 MPa, 562.9N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa.
The external M12x1.25 threaded stop with lock nut limits only the extend stroke length, leaving retract unaffected. Force remains unchanged. Deceleration relies on a fixed elastomer bumper, not an adjustable air cushion. A plain cylinder will not hold a load on air loss; use an external rod lock for fail-safe holding.
