Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-10B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-10B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 90mm 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 ACQJ32X90-10B
The AirTAC ACQJ32X90-10B is a double-acting JIS compact cylinder featuring a male-thread piston rod (M14x1.5) for direct load coupling. An external stop with a lock nut limits the extend end position, providing an on-machine adjustable window of 10mm. This yields a usable extend range of 80-90mm from the 90mm full stroke, while the retract stroke remains completely unaffected.
Because the adjustment only restricts travel length and not piston area, the output force is identical to a standard ACQ of the same bore. Expect 402.1N of push force and 301.6N of pull force at 0.5MPa. The unit relies on a fixed NBR elastomer bumper at each end for deceleration and includes sensor grooves, though this specific configuration ships without a magnet.

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 ACQJ32X90-10B Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC machining center during initial setup without machining custom spacers.
Product Line Changeover
Quickly modify the extend endpoint within the 80-90mm range when switching between different product heights on a packaging conveyor.
Assembly Press Tuning
Test and set precise trial end positions for pressing subcomponents before finalizing the mechanical hard stop.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-10B the Right Cylinder?
When sizing this 32mm bore actuator, consider the 402.1N push force at 0.5MPa. If your application requires less thrust, stepping down to a 25mm bore yields 245.4N push, whereas scaling up to a 40mm bore provides 628.3N. If your end position never varies, a fixed-stroke ACQ cylinder is sufficient. To order this adjustable version correctly, confirm the 90mm full stroke, 10mm window, the male M14x1.5 rod thread, and note that no magnet (-S) is installed.
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 ACQJ32X90-10B FAQ
The usable extend range is 80-90mm (90mm full stroke minus a 10mm window). It delivers 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 retract stroke is unaffected by the adjuster.
The external M12x1.25 threaded stop with lock nut limits only the extend travel length, meaning the force is identical to a standard ACQ because piston area is unchanged. The cylinder uses a fixed elastomer bumper for deceleration rather than an adjustable air cushion, and this specific model ships without a magnet.
