Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X30-10S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X30-10S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 30mm 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 ACQJ40X30-10S
The AirTAC ACQJ40X30-10S is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend stroke from 20 mm up to the full 30 mm directly on the machine, while the retract stroke remains completely unaffected.
Because the piston area is unchanged, output force equals a standard ACQ of the same bore, delivering 628.3 N push at 0.5 MPa. The body features fixed elastomer bumpers and integrated magnetic-switch grooves, with the included -S magnet ready for reed or solid-state sensors.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Full stroke | 30 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 ACQJ40X30-10S Is Used
Machining Fixture Stops
Dial in the exact 20 to 30 mm extend position for varying part heights on a CNC lathe without machining custom spacers.
Carton Changeover Flaps
Rapidly adapt a carton sealing machine to new box dimensions by tweaking the external lock nut on the fly.
Press Trial Positions
Test different clamping depths on an assembly press safely before locking the final extend stop in place.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X30-10S the Right Cylinder?
This 40 mm bore unit provides 628.3 N push force at 0.5 MPa, sitting between the 32 mm bore (402.1 N push) and the 50 mm bore (981.8 N push). If your setup never requires end-position adjustments, a fixed-stroke ACQ cylinder will suffice. When ordering, confirm the 30 mm full stroke, the 10 mm adjuster window, the -S magnet option, and the default female M8x1.25 rod-end 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 ACQJ40X30-10S FAQ
It provides 628.3 N push and 527.8 N pull force at 0.5 MPa, 879.6 N push at 0.7 MPa, and a maximum push of 128 kgf at 1.0 MPa. The full stroke is 30 mm with a 10 mm adjustment window, yielding a usable extend range of 20-30 mm.
No, the adjuster only changes the extend stroke length, not the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for end-of-stroke deceleration, and the -S magnet works with both reed and solid-state electronic switches.
