Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-100S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-100S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 150mm 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 ACQJ32X150-100S
The AirTAC ACQJ32X150-100S is a double-acting JIS compact cylinder featuring a 150mm full stroke and a built-in piston magnet. As a long-stroke made-to-order variant, it exceeds the standard 100mm maximum for the 32mm bore, extending up to the 300mm range. It uses an external M12x1.25 threaded stop with a lock nut to limit the extend stroke, providing a usable extend range of 50-150mm. The retract distance remains completely unaffected by this adjustment.
Because the adjustment mechanism only restricts rod travel, the piston area stays the same, meaning the output force is identical to a standard ACQ of this bore. You get 402.1N of push force and 301.6N of pull force at 0.5MPa. The unit features fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration and includes magnetic-switch grooves for position sensing.

| 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 ACQJ32X150-100S Is Used
Machining Fixture Stops
Dial in the exact extend position on a CNC machining fixture during product changeover without machining new stop blocks.
Carton Sealing Tensioners
Adjust the extend endpoint on a packaging line to accommodate varying box heights and flap thicknesses on the fly.
Assembly Press Trials
Set trial end positions for pressing bearings on an assembly line, fine-tuning the 50-150mm stroke window per part run.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X150-100S the Right Cylinder?
If you do not require on-machine extend tuning, a fixed-stroke ACQ32x150 is simpler and suffices. When sizing this series, consider the neighbouring bores: stepping down to a 25mm bore yields 245.4N push at 0.5MPa, while stepping up to a 40mm bore provides 628.3N push at 0.5MPa. To order this exact unit, confirm the 32mm bore, 150mm full stroke, 100mm adjustment window, the -S magnet for electronic or reed switches, and the default female M8x1.25 rod-end thread. Remember that a plain ACQ-type cylinder will not hold its load on air loss; install an external rod lock or pilot-operated check valve for fail-safe holding.
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 ACQJ32X150-100S FAQ
This long-stroke cylinder has a 150mm full stroke with a 100mm adjustment window, allowing a usable extend range of 50-150mm. It delivers 402.1N push and 301.6N pull force at 0.5MPa, 562.9N push at 0.7MPa, and a maximum push of 82kgf at 1.0MPa. The port size is PT1/8.
The external M12x1.25 threaded stop with a lock nut limits only the extend stroke length, leaving the retract stroke unaffected. Because the piston area is unchanged, the force remains identical to a standard ACQ. The cylinder uses fixed NBR elastomer bumpers at each end for deceleration, not adjustable air cushions, so external shock absorbers are recommended for high-energy loads. The -S magnet works with reed or solid-state switches.
