Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X40-40S
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X40-40S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 40mm full stroke. Turn the stop to fine-tune the end position on the machine without changing parts.

About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X40-40S
The AirTAC ACQJ80X40-40S is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that limits the extend end position. You can fine-tune the usable extend stroke anywhere from 0 mm up to the full 40 mm directly on the machine, while the retract stroke remains completely unaffected.
Because the piston area stays the same, the output force equals a standard ACQ of this bore, delivering 2513.2 N push and 2267.8 N pull at 0.5 MPa. The unit integrates a fixed elastomer bumper for end-stop deceleration and includes a piston magnet (-S) for position sensing. It uses a PT3/8 port and a 25 mm rod with an M16x2.0 female rod-end thread.

| Rod thread | M16×2.0 (F) / M22×1.5 (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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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 ACQJ80-100 Adjustable Compact Cylinder ACQJ80X40-40S Is Used
Machining Clamp Tuning
Dial in the exact clamping reach on a CNC fixture without machining new spacers, shortening the extend stroke by up to 40 mm to accommodate varying raw stock thicknesses.
Packaging Diverter Setup
Adjust the extend stop on a packaging line diverter gate to test different carton sizes on the fly, ensuring precise routing without replacing the cylinder.
Press Stroke Trials
Set trial end positions on a light-duty assembly press, tweaking the extend stroke down from 40 mm to find the optimal forming depth before finalizing the mechanical setup.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X40-40S the Right Cylinder?
If your application needs less thrust, the adjacent 63 mm bore yields 1558.6 N push at 0.5 MPa, whereas stepping up to the 100 mm bore provides 3927.0 N. Choose this 80 mm bore if you require exactly 2513.2 N of push force alongside a 0-40 mm adjustable extend window. A fixed-stroke ACQ suffices if the extend end position never varies. Confirm your ordering essentials: 80 mm bore, 40 mm full stroke, 40 mm window, S magnet, and 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 ACQJ80-100 Adjustable Compact Cylinder ACQJ80X40-40S FAQ
This cylinder provides 2513.2 N push and 2267.8 N pull at 0.5 MPa, 3518.5 N push at 0.7 MPa, and a maximum push of 513 kgf at 1.0 MPa. The usable extend range is 0-40 mm (40 mm full stroke minus the 40 mm window). It features a 25 mm rod, an M16x2.0 female rod-end thread, an M20x1.5 external adjuster thread, and a PT3/8 port.
The external M20x1.5 threaded stop with a lock nut mechanically limits how far the rod extends, shortening the stroke length only. The force remains identical to a standard ACQ because the piston area is unchanged. A fixed elastomer bumper decelerates the load at stroke ends, but the cylinder will drift on air loss; use an external rod lock for fail-safe load holding.
