Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-30
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-30 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 ACQJ80X80-30
The AirTAC ACQJ80X80-30 is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut that restricts the extend stroke. You can fine-tune the extend end position on the machine, yielding a usable extend range of 50-80 mm. The retract stroke remains unaffected by this adjustment.
Because the piston area stays constant, output force equals that of a standard ACQ bore 80, delivering 2513.2 N push at 0.5 MPa. The unit uses a PT3/8 port and a 25 mm rod with an M16x2.0 female thread end. Fixed elastomer bumpers absorb end-of-travel shocks instead of adjustable air cushions.

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 ACQJ80X80-30 Is Used
Machining Fixture Stops
Dial in the exact extend position of a clamping arm on a CNC machining fixture during setup, adjusting the end stop by up to 30 mm without swapping out cylinder hardware.
Packaging Line Diverters
Reposition a product diverting gate on a packaging conveyor to handle different carton widths, utilizing the 50-80 mm adjustable extend range for rapid product changeover.
Assembly Press Stroke Trials
Test various pressing depths on an automated assembly line by turning the external M20x1.5 adjuster thread to find the optimal end position before finalizing the mechanical stop.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-30 the Right Cylinder?
When sizing this 80 mm bore actuator, note the 2513.2 N push force at 0.5 MPa. If your application requires less thrust, stepping down to a 63 mm bore yields 1558.6 N push, whereas scaling up to a 100 mm bore provides 3927.0 N. If the end position never varies, a fixed-stroke ACQ suffices. To order this adjustable unit correctly, confirm the 80 mm bore, 80 mm full stroke, 30 mm window, female rod thread, and whether a -S magnet is needed for sensing.
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 ACQJ80X80-30 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 full stroke is 80 mm with a 30 mm window, allowing an adjustable extend range of 50-80 mm.
The external threaded stop limits only the extend stroke length, meaning output force remains identical to a standard ACQ because the piston area is unchanged. The cylinder uses fixed elastomer bumpers for deceleration rather than adjustable air cushions. This specific model ships without a sensor magnet, though the body retains standard switch grooves for adding reed or solid-state sensors.
