About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-20
This double-acting single-rod JIS compact cylinder features an external threaded stop with a lock nut, allowing you to fine-tune the extend end position directly on the machine. For this ACQJ80X75-20 model, the full stroke is 75 mm, and the 20 mm adjustment window yields a usable extend range of 55-75 mm. The retract stroke remains completely unaffected by this mechanism.
Because the piston area is unchanged, the output force is identical to a standard ACQ of the same bore, delivering 2513.2 N push and 2267.8 N pull at 0.5 MPa. The cylinder body incorporates a fixed NBR elastomer bumper at each end for end-of-stroke deceleration and includes sensor grooves for adding reed or solid-state switches. It operates at 30-500 mm/s and uses a PT3/8 port with a 25 mm rod.

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 ACQJ80X75-20 Is Used
Machining Fixture Stops
Dial in the exact clamping reach on a CNC fixture during setup, allowing 55 to 75 mm of extend travel to accommodate varying part heights without swapping cylinders.
Packaging Diverter Arms
Adjust the extend position of a sorting gate on a packaging line to handle different carton widths, using the external stop to quickly change the end point during product changeover.
Assembly Press Positioning
Set trial end positions on an assembly press for inserting components, relying on the 2513.2 N push force at 0.5 MPa to seat parts while tuning the stroke in 20 mm of travel.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X75-20 the Right Cylinder?
When sizing this bore, dropping to a 63 mm cylinder reduces the push force to 1558.6 N at 0.5 MPa, whereas stepping up to a 100 mm bore increases it to 3927.0 N. If your application requires a fixed extend position and no future adjustments, a standard ACQ cylinder will suffice. To order this adjustable unit correctly, confirm the 80 mm bore, 75 mm full stroke, 20 mm window, female rod-end thread (M16x2.0), and whether you need the S magnet option 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 ACQJ80X75-20 FAQ
This 80 mm bore cylinder has a 75 mm full stroke with a 20 mm adjustable window, giving a usable extend range of 55-75 mm. It provides 2513.2 N push and 2267.8 N pull force at 0.5 MPa, 3518.5 N push at 0.7 MPa, and a maximum push of 513 kgf at 1.0 MPa.
The external M20x1.5 threaded stop with a lock nut limits how far the rod extends, shortening the extend stroke without changing the piston area, so the force remains identical to a standard ACQ. The retract stroke is unaffected, and the fixed NBR elastomer bumper decelerates the load at the ends, though an external shock absorber is recommended for high-energy loads.
