Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-10SB
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-10SB is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 75mm 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 ACQJ80X75-10SB
The ACQJ80X75-10SB is a double-acting JIS compact cylinder featuring a 75mm full stroke and a 10mm adjustable extend window, allowing you to set the forward end position anywhere between 65mm and 75mm. An external M20x1.5 threaded stop with a lock nut handles this on-machine tuning, meaning you can dial in the exact forward reach without swapping out components. The return stroke remains completely unaffected by this adjustment.
Because the internal piston area stays constant, output force is identical to a standard ACQ of the same 80mm bore. You get 2513.2N of push and 2267.8N of pull at 0.5MPa, rising to 3518.5N push at 0.7MPa, with a maximum push capacity of 513kgf at 1.0MPa. The unit incorporates fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration, and the included -S magnet works seamlessly with reed or solid-state electronic switches via the built-in grooves.

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 ACQJ80X75-10SB Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC fixture during setup, allowing 65 to 75mm of forward travel to accommodate different raw part sizes without changing hardware.
Packaging Diverters
Adjust the stroke length on a packaging line diverter to match varying box dimensions on the fly, ensuring precise product routing without mechanical rebuilds.
Assembly Press Tuning
Fine-tune the end position on an assembly press for trial runs, setting the exact insertion depth within the 10mm window before finalizing the automated cycle.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-10SB the Right Cylinder?
If you need slightly less force, the 63mm bore variant provides 1558.6N push at 0.5MPa, whereas stepping up to the 100mm bore yields 3927.0N push. Choose this 80mm bore when your application requires roughly 2.5kN of thrust. If your forward reach never varies, a fixed-stroke ACQ cylinder is sufficient. To order this adjustable version correctly, confirm the 80mm bore, 75mm full stroke, 10mm window, the -S magnet for sensing, and the -B male M22x1.5 rod thread that couples directly to your load.
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 ACQJ80X75-10SB FAQ
The usable extend range is 65-75mm (a 75mm full stroke shortened by up to a 10mm window). Force is identical to a standard ACQ: 2513.2N push and 2267.8N pull at 0.5MPa, 3518.5N push at 0.7MPa, and a maximum push of 513kgf at 1.0MPa.
An external M20x1.5 threaded stop with a lock nut limits the forward extension, changing only the stroke length and not the force. Fixed elastomer bumpers handle deceleration at both ends. Note that a plain ACQ-type cylinder does not hold its load on air loss; for a fail-safe hold, use an external rod lock or pilot-operated check valve.
