Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-100S
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-100S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 80mm 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 ACQJ40X80-100S
The AirTAC ACQJ40X80-100S 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 range from 0 up to 80mm directly on your machinery without swapping components. The retract stroke remains completely unaffected by this adjustment.
Because the piston area stays the same, output force is identical to a standard ACQ of this bore, delivering 628.3N push at 0.5MPa. The 16mm rod uses an M12x1.25 adjuster thread, and the body features fixed elastomer bumpers at each end. Equipped with a magnet (-S), the integrated sensor grooves accept both reed and solid-state switches.

| 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 ACQJ40X80-100S Is Used
Machining Fixture Stops
Dial in the exact clamping extension on a CNC mill fixture during prototype runs without machining new stop collars.
Packaging Diverters
Adjust the stroke length on a packaging line diverter to handle varying carton widths during product changeover.
Assembly Press Setup
Set trial end positions for pressing bearings on an automated assembly line to find the optimal seating depth.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X80-100S the Right Cylinder?
If you need less push force at 0.5MPa, the 32mm bore provides 402.1N, whereas stepping up to the 50mm bore yields 981.8N. A fixed-stroke ACQ suffices if your extend end position never requires variation. To order this unit correctly, confirm the 40mm bore, 80mm full stroke, 100mm adjustment window, the -S magnet option, and your required 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 ACQJ40X80-100S FAQ
The usable extend range is 0-80mm. It delivers 628.3N push and 527.8N pull at 0.5MPa, 879.6N push at 0.7MPa, and a maximum push of 128kgf at 1.0MPa. The adjustment window is 100mm.
No, the external M12x1.25 threaded stop changes stroke length only, so force remains identical to a standard ACQ. Deceleration relies on fixed elastomer bumpers, not adjustable air cushions. The -S magnet works with reed or solid-state switches.
