Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-20
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-20 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 ACQJ32X100-20
The AirTAC ACQJ32X100-20 is a double-acting JIS compact cylinder with a 32mm bore and a 100mm full stroke. An external threaded stop with a lock nut limits the extend end position, giving a usable extend range of 80 to 100mm. The retract stroke remains unaffected by this adjustment. Because the piston area is unchanged, the output force equals that of a standard ACQ of the same bore.
This unit delivers 402.1N of push force and 301.6N of pull force at 0.5MPa. It features a 16mm rod, a PT1/8 port, and fixed elastomer bumpers at both ends for end-of-stroke deceleration. The body includes magnetic-switch grooves, though this specific configuration ships without a magnet. Operating pressure ranges from 0.15 to 1.0MPa.

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 ACQJ32X100-20 Is Used
Machining Fixture Stops
Dial in the exact extend position of clamping arms on a CNC lathe without machining custom spacers.
Product Changeover Diverters
Quickly reposition a sorting gate on packaging lines to handle varying carton lengths.
Assembly Press Positioning
Set precise trial end positions for pressing bearings without swapping out the entire actuator.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X100-20 the Right Cylinder?
Selecting this 32mm bore provides 402.1N push at 0.5MPa, sitting between the 25mm bore (245.4N push) and the 40mm bore (628.3N push). A standard fixed-stroke ACQ is sufficient if your extend end position never requires on-machine fine-tuning. When ordering, confirm the 32mm bore, 100mm full stroke, 20mm adjustment window, female rod-end thread M8x1.25, and whether a -S magnet is needed for sensor tracking.
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 ACQJ32X100-20 FAQ
This cylinder provides 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. The full stroke is 100mm with a 20mm adjustment window, yielding a usable extend range of 80-100mm.
An external M12x1.25 threaded stop with a lock nut limits the extend stroke so you can tune the end position on the machine. The adjuster changes stroke length only, so force is identical to a standard ACQ. Deceleration is handled by fixed elastomer bumpers, not an adjustable air cushion.
