The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-75B 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.
The AirTAC ACQJ80X80-75B is a double-acting JIS compact cylinder with an 80mm full stroke and a 75mm adjustable extend window. An external M20x1.5 threaded stop and lock nut restricts how far the rod travels outward, yielding a usable extension range of 5-80mm. The return stroke remains fixed at 80mm. Because the piston area stays constant, output force matches a standard ACQ exactly.
This 80mm bore unit delivers 2513.2N push and 2267.8N pull at 0.5MPa, rising to 3518.5N push at 0.7MPa. It features a 25mm rod, PT3/8 port, and a male M22x1.5 rod-end for direct load coupling. The body includes sensor grooves, though this specific configuration ships without a magnet. Fixed NBR elastomer bumpers absorb impact at both ends rather than 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.
| 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.

Dial in the exact clamping extension on machining centers during part-changeover without swapping out the entire cylinder assembly.
Adjust the pressing height on packaging lines to accommodate varying box sizes, ensuring consistent flap closure.
Fine-tune the extend limit on light-duty presses to test trial end positions before finalizing the mechanical hard stop.
Select this 80mm bore actuator when your setup requires variable extend endpoints between 5 and 80mm without machining new parts. If your application needs less push force at 0.5MPa, consider the 63mm bore (1558.6N); if you need more power, the 100mm bore provides 3927.0N. A fixed-stroke ACQ is sufficient if your end position never varies. Verify your ordering code includes the 80mm stroke, 75mm window, male rod thread (-B), and add the -S magnet option if position sensing is required.
Quick checklist
It provides 2513.2N push and 2267.8N pull at 0.5MPa, and 3518.5N push at 0.7MPa, with a maximum push of 513kgf at 1.0MPa. The full stroke is 80mm, but the external adjuster allows you to shorten the extend stroke by up to 75mm, giving a usable extend range of 5-80mm. The retract stroke remains 80mm.
The M20x1.5 threaded stop with lock nut physically limits outward rod travel, changing only the stroke length, not the piston area, so force is identical to a standard ACQ. Fixed elastomer bumpers decelerate the load near stroke ends. A plain cylinder does not hold its load on air loss; install an external rod lock or pilot-operated check valve for fail-safe holding.
