Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-20B
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-20B 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 ACQJ80X80-20B
The ACQJ80X80-20B is a double-acting JIS compact cylinder featuring an external threaded stop that limits the extend stroke. You can fine-tune the extend end position on the machine itself, yielding a usable extend range of 60-80mm out of the 80mm full stroke. The retract distance remains completely unaffected by this adjustment. Because the piston area stays the same, output force is identical to a standard ACQ of this bore.
This unit delivers 2513.2N of push force and 2267.8N of pull force at 0.5MPa, reaching 3518.5N push at 0.7MPa. It features a 25mm piston rod with a male M22x1.5 thread end for direct load coupling, a PT3/8 port, and fixed NBR elastomer bumpers at both ends. The body includes sensor grooves, though this specific configuration ships without a magnet.

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 ACQJ80X80-20B Is Used
Machining Fixture Tuning
Dial in the exact extend stop during trial cuts on a CNC fixture, shortening the stroke up to 20mm to accommodate different raw casting lengths without swapping cylinders.
Packaging Diverter Setup
Adjust the pusher end position on a packaging line diverter to handle varying carton widths, using the external M20x1.5 adjuster to set the 60-80mm range precisely.
Assembly Press Positioning
Set the exact lower end position for a pressing operation on an assembly line, fine-tuning the contact depth on the machine without disassembling the tooling.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-20B the Right Cylinder?
Stepping down to a 63mm bore lowers the 0.5MPa push force to 1558.6N, while a 100mm bore raises it to 3927.0N. Choose this 80mm option when you need approximately 2513N of push and on-the-fly stroke tuning. If the extend position never varies, a fixed-stroke ACQ cylinder is sufficient. When ordering, verify the 80mm bore, 80mm full stroke, 20mm window, male M22x1.5 rod thread, and confirm whether a magnet is needed since this variant lacks one.
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 ACQJ80X80-20B FAQ
At 0.5MPa, the push force is 2513.2N and the pull force is 2267.8N. At 0.7MPa, the push force is 3518.5N, with a maximum push of 513kgf at 1.0MPa. The usable extend range is 60-80mm, meaning the 20mm window allows shortening the 80mm full extend stroke by up to 20mm.
The external threaded stop with a lock nut physically limits how far the rod extends, changing only the stroke length and not the piston area, so force remains identical to a standard ACQ. The retract stroke is unaffected. Deceleration is handled by fixed NBR elastomer bumpers at each end, not an adjustable air cushion.
