Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-10
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-10 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 ACQJ80X50-10
The AirTAC ACQJ80X50-10 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 range from 40 mm up to the full 50 mm stroke directly on the machine without swapping parts. The retract stroke remains unaffected. An M20x1.5 adjuster thread sets the extend limit.
Because the piston area is unchanged, the force output is identical to a standard ACQ of this bore. The 80 mm bore yields 2513.2 N of push force and 2267.8 N of pull force at 0.5 MPa. The body features fixed elastomer bumpers at both ends for end-of-stroke deceleration and includes magnetic-switch grooves, though this specific configuration ships without a magnet.

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 ACQJ80X50-10 Is Used
Machining Fixture Stops
Dial in the exact extend position on a milling fixture when raw material thickness varies, ensuring the clamp hits the correct spot every time without remachining stops.
Carton Changeover Diverters
Adjust the extend endpoint on a packaging line diverter to accommodate different box sizes during product changeovers, reducing mechanical setup time.
Press Trial Positions
Set trial end positions on an assembly press to test component insertion depths before locking the lock nut, preventing damage during prototype runs.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X50-10 the Right Cylinder?
When sizing this 80 mm bore actuator, consider the 63 mm bore if your required 0.5 MPa push force is under 1558.6 N, or step up to the 100 mm bore for 3927.0 N of push force. If your end-position requirements never vary, a fixed-stroke ACQ cylinder suffices. For this adjustable model, confirm the 50 mm full stroke, the 10 mm adjustment window, the female M16x2.0 rod thread, the PT3/8 port, and whether you need the -S magnet option for sensor tracking.
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 ACQJ80X50-10 FAQ
At 0.5 MPa, the push force is 2513.2 N and the pull force is 2267.8 N. At 0.7 MPa, the push force is 3518.5 N, with a maximum push force of 513 kgf at 1.0 MPa. The usable extend range is 40-50 mm, meaning the 10 mm window can shorten the 50 mm full stroke. The retract stroke is unaffected.
No, the external M20x1.5 threaded stop only changes the extend stroke length, not the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for deceleration, not an adjustable air cushion or load-holding brake. For fail-safe load holding on air loss, use an external rod lock.
