Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X45-10
The AirTAC Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X45-10 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø40mm bore and 45mm 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 ACQJ40X45-10
The AirTAC ACQJ40X45-10 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 extend stroke on the machine across a 35-45 mm usable range, while the retract stroke remains completely unaffected.
Because the adjuster only alters travel length and not piston area, output force stays identical to a standard ACQ of this bore. The 40 mm bore delivers 628.3 N push at 0.5 MPa, running through a PT1/8 port. The body features fixed NBR elastomer bumpers at each end for end-of-stroke deceleration.

| Model | Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X45-10 |
|---|---|
| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Full stroke | 45 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 ACQJ40X45-10 Is Used
Machining Fixture Stops
Dial in the extend position within the 35-45 mm window on CNC machining fixtures to accommodate raw part tolerances without swapping cylinder hardware.
Product Changeover Pins
Quickly reposition the extend stop on packaging conveyors during format changes, using the external M12x1.25 adjuster to set new product push distances.
Assembly Press Trials
Test trial end positions on automated assembly presses, relying on the fixed elastomer bumper to handle deceleration while finding the optimal contact point.
Is the Airtac ACQJ32~40 Adjustable Thin-Type Cylinder ACQJ40X45-10 the Right Cylinder?
If you need slightly less push, the 32 mm bore yields 402.1 N at 0.5 MPa, whereas stepping up to the 50 mm bore provides 981.8 N. Choose this 40 mm option when your setup requires precise 35-45 mm extend positioning. A fixed-stroke ACQ cylinder is sufficient if your end stop never varies. Confirm your ordering details: 40 mm bore, 45 mm full stroke, 10 mm window, female M8x1.25 rod thread, and no magnet.
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 ACQJ40X45-10 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 35-45 mm, created by a 10 mm adjustable window on the 45 mm full stroke.
No, the adjuster only limits how far the rod extends, leaving the retract stroke unaffected. Force remains identical to a standard ACQ because the piston area is unchanged. Deceleration is handled by fixed elastomer bumpers, and this specific model ships without a sensor magnet.
