Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-30B
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-30B is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø32mm bore and 45mm 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 ACQJ32X45-30B
The AirTAC ACQJ32X45-30B is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. You can fine-tune the usable extend stroke anywhere from 15mm up to the full 45mm directly on your machine, while the retract stroke remains completely unaffected. Because the piston area stays the same, force output is identical to a standard ACQ of this bore.
This 32mm bore unit pushes with 402.1N and pulls with 301.6N at 0.5 MPa. It ships with a male M14x1.5 piston rod end (-B) for direct load coupling, a PT1/8 port, and an M12x1.25 adjuster thread. The body incorporates fixed NBR elastomer bumpers at each end for end-of-stroke deceleration, alongside integrated sensor grooves, though this specific configuration omits the internal magnet.

| 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 ACQJ32X45-30B Is Used
Machining Fixture Stops
Dial in the exact extend position of clamping arms on CNC machining centers during part changeovers without machining new spacers.
Carton Sealing Turrets
Adjust the fold-over stroke length on packaging turrets to accommodate varying box heights rapidly on the fly.
Assembly Press Positioning
Set trial end positions for pressing sub-components on automated assembly lines until the optimal depth is found.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ32X45-30B the Right Cylinder?
If your application requires less push force, the 25mm bore offers 245.4N at 0.5 MPa; for heavier loads, step up to the 40mm bore providing 628.3N. A standard fixed-stroke ACQ cylinder is sufficient if your extend position never requires adjustment. When ordering this adjustable variant, confirm the 32mm bore, 45mm full stroke, 30mm adjustment window, male M14x1.5 rod thread, and that no magnet (-S) is required.
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 ACQJ32X45-30B FAQ
The usable extend range is 15-45mm (a 45mm full stroke shortened by up to a 30mm window). At 0.5 MPa it pushes with 402.1N and pulls with 301.6N; at 0.7 MPa push is 562.9N. The maximum push force is 82 kgf at 1.0 MPa.
The external M12x1.25 threaded stop with lock nut limits the extend stroke length only, meaning force is identical to a standard ACQ. The retract stroke is unaffected. Deceleration is handled by fixed NBR elastomer bumpers, not adjustable air cushions, so external shock absorbers may be needed for high-energy loads.
