Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-30S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-30S 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 ACQJ40X60-30S
The AirTAC ACQJ40X60-30S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend stroke. You can fine-tune the extend end position directly on your machinery, providing a usable extend range of 30-60 mm from the 60 mm full stroke. The retract stroke remains completely unaffected by this mechanism.
Because the piston area stays constant, the output force equals that of a standard ACQ bore 40 cylinder, yielding 628.3 N push and 527.8 N pull at 0.5 MPa. The rod end uses an M8x1.25 female thread, and the external adjuster utilizes an M12x1.25 thread. Fixed elastomer bumpers handle end-of-stroke deceleration, while the built-in magnet (-S) enables position sensing with reed or solid-state switches.

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 ACQJ40X60-30S Is Used
Multi-Fixture Machining
Adapts clamping reach on machining centers when swapping raw material blanks of varying thicknesses without disassembling the pneumatic setup.
Assembly Line Changeover
Quickly modifies part-push distances during product family transitions on automated assembly equipment to maintain correct insertion depths.
Carton Flap Folding
Sets precise folding arm endpoints for different package heights on packaging lines, ensuring consistent flap positioning without parts replacement.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X60-30S the Right Cylinder?
If you need slightly less force, the bore 32 version provides 402.1 N push at 0.5 MPa, whereas stepping up to the bore 50 model yields 981.8 N push. A fixed-stroke ACQ40 cylinder is sufficient if your end position never varies. To order this adjustable variant correctly, confirm the 40 mm bore, 60 mm full stroke, 30 mm adjust window, the -S magnet for sensing, and the female 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 ACQJ40X60-30S FAQ
It provides 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 usable extend range is 30-60 mm, set by the 30 mm adjustment window on the 60 mm full stroke.
The external M12x1.25 threaded stop and lock nut only shorten the extend stroke; they do not alter piston area, so force remains identical to a standard ACQ. Fixed elastomer bumpers absorb end-impact energy, and the included magnet works with reed or solid-state switches.
