Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-20S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-20S 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 ACQJ40X60-20S
The AirTAC ACQJ40X60-20S is a double-acting JIS compact cylinder featuring an external extend stop. A threaded M12x1.25 adjuster with a lock nut lets you fine-tune the extend end position on the machine, providing a usable extend range of 40-60 mm from the 60 mm full stroke. The retract stroke remains completely unaffected by this mechanism.
Output force stays identical to a standard ACQ of the same bore because the piston area is unchanged, delivering 628.3 N push at 0.5 MPa. The body integrates magnetic-switch grooves compatible with reed or solid-state sensors, and relies on a fixed NBR elastomer bumper at each end for end-of-stroke deceleration.

| 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 (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 ACQJ40X60-20S Is Used
Machining Fixture Stops
Dial in the exact clamping extension on a CNC machining center without swapping out cylinder hardware during setup changes.
Product Changeover Guides
Adjust the extend stroke on packaging lines to accommodate varying carton sizes on the fly using the external stop nut.
Assembly Press Positioning
Set trial end positions for pressing operations on automated assembly equipment to find the optimal contact depth.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-20S the Right Cylinder?
If your application requires less thrust, the 32 mm bore variant provides 402.1 N push at 0.5 MPa, whereas stepping up to the 50 mm bore yields 981.8 N. Choose this 40 mm bore when your fixture demands exactly 527.8 N pull force at 0.5 MPa alongside a 60 mm maximum stroke. If the end position never varies, a fixed-stroke ACQ cylinder is sufficient. When ordering, confirm the 40 mm bore, 60 mm full stroke, 20 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 ACQJ40X60-20S FAQ
This cylinder 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 20 mm adjustment window allows a usable extend range of 40-60 mm.
No, the external M12x1.25 threaded stop only changes the extend length, leaving the piston area and output force identical to a standard ACQ. Deceleration is handled by fixed elastomer bumpers, and the S magnet works with reed or solid-state switches.
