Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-50
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-50 is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 50mm 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 ACQJ80X50-50
The AirTAC ACQJ80X50-50 is a double-acting JIS compact cylinder with an external threaded stop and lock nut that limits the extend end position. You can fine-tune the usable extend travel anywhere from 0 mm up to the full 50 mm directly on your machinery, while the retract stroke remains completely unaffected. This on-machine adjustability eliminates the need to swap physical parts during setup changes or product changeovers.
Because the adjuster only restricts travel length and not the piston area, the generated force stays identical to a standard ACQ of the same bore. At 0.5 MPa it yields 2513.2 N of push and 2267.8 N of pull, reaching 3518.5 N push at 0.7 MPa with a maximum push capacity of 513 kgf at 1.0 MPa. The unit features a 25 mm rod, a PT3/8 port, an M20x1.5 external adjuster thread, and fixed NBR elastomer bumpers at both ends for end-stop deceleration.

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 ACQJ80X50-50 Is Used
Machining Clamp Positioning
Dial in the exact extend stop from 0 to 50 mm on a CNC fixture to accommodate varying raw material thicknesses without machining custom spacer blocks.
Packaging Diverter Arms
Adjust the extend endpoint on a sorting diverter to handle different carton sizes on the fly, ensuring proper routing without changing the cylinder hardware.
Assembly Press Stops
Set precise lower-end travel limits on a light assembly press to control insertion depth, relying on the 2513.2 N push force to seat components reliably.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-50 the Right Cylinder?
When sizing this 80 mm bore actuator, consider the adjacent options in the range. Stepping down to a 63 mm bore lowers the 0.5 MPa push force to 1558.6 N, whereas moving up to a 100 mm bore increases it to 3927.0 N. If your application requires a fixed 50 mm extend stroke without any on-site position tuning, a standard ACQ80X50 cylinder will suffice. To order this adjustable model correctly, confirm the 80 mm bore, 50 mm full stroke, 50 mm adjustment window, female rod-end thread (M16x2.0), and note that this specific configuration ships without a piston magnet.
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 ACQJ80X50-50 FAQ
The usable extend range is 0-50 mm (full stroke 50 mm minus a 50 mm adjustment window). The force is identical to a standard ACQ: push is 2513.2 N and pull is 2267.8 N at 0.5 MPa, push is 3518.5 N at 0.7 MPa, and maximum push is 513 kgf at 1.0 MPa.
An external M20x1.5 threaded stop with a lock nut limits the extend stroke only; the retract stroke is unaffected. The cylinder uses fixed NBR elastomer bumpers at each end rather than adjustable air cushions. This model ships without a piston magnet, though the body retains sensor grooves for adding external reed or solid-state switches.
