About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-75S
The AirTAC ACQJ80X75-75S is a double-acting JIS compact cylinder with an external extend stop, letting you fine-tune the forward end position directly on your equipment. With a 75mm full stroke and a 75mm adjustment window, the usable extend range spans 0-75mm. The retract stroke remains completely unaffected. An M20x1.5 adjuster thread with a lock nut secures the setting.
Because the adjustment only limits travel length, the piston area stays the same, meaning force is identical to a standard ACQ of this bore. This 80mm bore unit features a 25mm rod, PT3/8 porting, fixed NBR elastomer bumpers, and a built-in magnet (-S) compatible with reed or solid-state switches.

Specifications follow the official AirTAC ACQJ datasheet. The adjustable stop shortens the EXTEND stroke only; ACQJ is double-rod, so push is lower than 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 | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
ACQJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod ACQ push of the same bore. Actual usable force is lower due to friction; size with a safety margin.

Where the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-75S Is Used
Machining Fixture Stops
Dial in the exact clamping extension on CNC machining centers during part setups without machining new spacer blocks.
Product Changeover Diverters
Quickly reposition conveyor sorting gates for different package sizes by rotating the external stopper nut.
Packaging Plunge Depth
Test and set the precise downward travel for sealing jaws or forming tools on packaging lines to prevent product crushing.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-75S the Right Cylinder?
A fixed-stroke ACQ cylinder is sufficient if your extend position never needs variation. When ordering, confirm the 80mm bore, 75mm full stroke, 75mm window, the -S magnet for sensing, and the default female M16x2.0 rod-end 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 ACQJ80X75-75S FAQ
The usable extend range is 0-75mm (75mm full stroke minus the 75mm window).
An external M20x1.5 threaded stop with a lock nut limits the forward travel length without altering piston area, so force remains unchanged. The cylinder uses fixed NBR elastomer bumpers at both ends rather than adjustable air cushions. The included -S magnet works with both reed and electronic solid-state switches.
