Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-40
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-40 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 80mm 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 ACQJ80X80-40
The ACQJ80X80-40 is a double-acting JIS compact cylinder featuring an external M20x1.5 threaded stop with a lock nut. This mechanism lets you fine-tune the extend end position directly on your machinery, providing a usable outward travel range of 40 to 80 mm from a standard 80 mm full stroke. The return stroke remains completely unaffected by this adjustment.
Because the piston area stays constant, output force equals a standard ACQ of this size, giving 2513.2 N push and 2267.8 N pull at 0.5 MPa. The unit incorporates a fixed NBR elastomer bumper at each end for end-of-stroke deceleration and includes sensor grooves, though this specific configuration ships without a magnet. Operating pressure spans 0.15 to 1.0 MPa, and the PT3/8 port handles airflow efficiently.

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 ACQJ80X80-40 Is Used
Machining Fixture Clamps
Dial in the exact clamping reach on a CNC fixture during setup. The external stop adjusts outward travel from 40 to 80 mm without swapping hardware for different part heights.
Carton Sealing Stops
Accommodate various box sizes on a packaging line. The lock nut allows rapid product-changeover by shifting the extend endpoint to match specific flap dimensions.
Press Trial Positions
Establish safe trial end positions on light assembly presses. The adjuster limits the extend stroke to prevent tool damage, while the fixed bumper absorbs residual kinetic energy.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-40 the Right Cylinder?
Choosing this 80 mm bore yields 2513.2 N of thrust at 0.5 MPa. If your application requires less force, stepping down to a 63 mm bore provides 1558.6 N, whereas moving up to a 100 mm bore offers 3927.0 N. A fixed-stroke ACQ80 is preferable if exact end positions never vary. When ordering, verify the 80 mm bore, 80 mm full stroke, 40 mm adjustment window, female M16x2.0 rod-end thread, and PT3/8 porting. Remember to add the -S suffix if magnetic sensing is required later.
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 ACQJ80X80-40 FAQ
At 0.5 MPa, the push force is 2513.2 N and the pull force is 2267.8 N. At 0.7 MPa, the push force is 3518.5 N, with a maximum push of 513 kgf at 1.0 MPa. The usable extend range is 40 to 80 mm, achieved by shortening the 80 mm full stroke via the 40 mm adjustment window.
No, the M20x1.5 external stop changes only the extend length, not the piston area, so force remains identical to a standard ACQ. Deceleration is handled by a fixed NBR elastomer bumper at each end. Note that this model ships without a sensor magnet and does not hold loads on air loss without an external rod lock.
