Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-30SB
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-30SB 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 ACQJ32X90-30SB
The AirTAC ACQJ32X90-30SB is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend stroke. You get a usable extend range of 60-90 mm, fine-tuned directly on the machine, while the retract stroke remains unaffected. It includes a male M14x1.5 rod end and a piston magnet for sensing.
Because the adjuster only changes travel length, the piston area stays the same. This means force is identical to a standard ACQ of this bore, delivering 402.1 N push at 0.5 MPa. The body uses fixed elastomer bumpers instead of adjustable air cushions, and the M12x1.25 adjuster thread allows precise end-position control.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø32 mm |
| Full stroke | 90 mm |
| 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 |
| Temperature | -20 to +70 °C |
| 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 ACQJ32X90-30SB Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC fixture. The 60-90 mm extend window lets operators accommodate varying part sizes without machining new spacers.
Packaging Changeover
Adapt product diverters or sealing heads during format changes. The external stop retunes the extend endpoint in seconds to match new carton dimensions.
Assembly Press Trials
Test insertion depths on automated assembly lines. Adjust the stroke externally to find the perfect pressing position before locking the nut down.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X90-30SB the Right Cylinder?
If you need slightly less push force, the 25 mm bore yields 245.4 N at 0.5 MPa, whereas stepping up to the 40 mm bore provides 628.3 N. This 32 mm bore hits a solid middle ground at 402.1 N push and 301.6 N pull. If your application never requires end-position changes, a fixed-stroke ACQ cylinder is sufficient. When ordering this adjustable version, confirm the 90 mm full stroke, 30 mm window, S magnet, and B male 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 ACQJ32X90-30SB FAQ
The usable extend range is 60-90 mm. Force is identical to a standard ACQ: 402.1 N push and 301.6 N pull at 0.5 MPa, 562.9 N push at 0.7 MPa, and a maximum push of 82 kgf at 1.0 MPa. The 30 mm adjustment window only limits stroke length, not force.
An external M12x1.25 threaded stop with a lock nut limits the extend travel, while fixed elastomer bumpers absorb end-of-stroke impact. The cylinder does not hold its load if air is lost; for fail-safe load holding, you must add an external rod lock or pilot-operated check valve.
