Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-20
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-20 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 60mm 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 ACQJ40X60-20
The AirTAC ACQJ40X60-20 is a double-acting JIS compact cylinder with an external M12x1.25 threaded stop and lock nut that limits the extend stroke. You get a usable extend range of 40 to 60 mm, while the retract stroke remains completely unaffected. This allows on-machine end-position tuning without swapping parts.
Because the piston area is unchanged, output force matches a standard ACQ exactly, delivering 628.3 N push and 527.8 N pull at 0.5 MPa. The 40 mm bore uses a PT1/8 port and a Ø16 mm rod with an M8x1.25 female thread. Fixed NBR elastomer bumpers handle end-of-stroke deceleration, and the body retains sensor grooves for adding switches later.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-20 |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Full stroke | 60 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 ACQJ40X60-20 Is Used
Machining Fixture Stops
Dial in the extend position from 40 to 60 mm on a CNC machining fixture to accommodate raw part size variations without fabricating new hard stops.
Packaging Changeover
Rapidly adjust the extend end position during packaging line product changeovers by turning the external M12x1.25 adjuster screw to meet new carton dimensions.
Assembly Press Trials
Set trial end positions on automated assembly presses, fine-tuning the 40 to 60 mm stroke window to dial in precise insertion depths for new components.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-20 the Right Cylinder?
Selecting this 40 mm bore gives 628.3 N push at 0.5 MPa, sitting between the 32 mm (402.1 N) and 50 mm (981.8 N) options. If your extend position never varies, a fixed-stroke ACQ is simpler. When ordering, confirm the 60 mm full stroke, the 20 mm adjuster window, the female rod thread, and whether you need the S magnet option for position sensing.
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 ACQJ40X60-20 FAQ
It delivers 628.3 N push and 527.8 N pull 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 60 mm with a 20 mm adjustment window, giving a usable extend range of 40 to 60 mm.
An external M12x1.25 threaded screw with a lock nut limits the extend stroke, allowing on-machine tuning without changing parts. The adjuster only changes stroke length, so force remains identical to a standard ACQ. Fixed NBR elastomer bumpers absorb end impact, and the body includes sensor grooves for future switch installation.
