Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-20
The AirTAC Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-20 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.

About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-20
The AirTAC ACQJ80X80-20 is a double-acting JIS compact cylinder featuring an external threaded stop with a lock nut. This mechanism permits on-machine extend end-position tuning, yielding a usable outward travel span of 60 to 80 mm. The inward return distance remains completely unaffected by this adjustment.
Because the piston area stays constant, output force equals that of a standard ACQ counterpart, delivering 2513.2 N of push at 0.5 MPa. The unit integrates fixed NBR elastomer bumpers at both ends for end-of-travel deceleration and includes sensor grooves, though this specific configuration ships without a magnet.

| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| Rod thread | M16×2.0 (F) / M22×1.5 (B) |
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 ACQJ80X80-20 Is Used
Press Tonnage Trials
Dial in the exact 60-80mm extend reach during stamping press setup to test different material thicknesses without machining new spacers.
Carton Size Changeover
Adapt the end stop position on a packaging line when switching to a different cardboard blank size, keeping the retract stroke fixed.
Assembly Fixture Profiling
Find the optimal end position for clamping varied product geometries on an assembly fixture directly at the machine.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X80-20 the Right Cylinder?
If your application requires less thrust, the ACQJ63 bore provides 1558.6 N push at 0.5 MPa, whereas stepping up to the ACQJ100 bore yields 3927.0 N. A fixed-stroke ACQ80 is sufficient if the outward endpoint never needs tweaking. To order this adjustable variant correctly, confirm the 80 mm bore, 80 mm full stroke, 20 mm window, female M16x2.0 rod end, and PT3/8 porting.
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 ACQJ80X80-20 FAQ
It delivers 2513.2 N push and 2267.8 N pull at 0.5 MPa, 3518.5 N push at 0.7 MPa, and a maximum push of 513 kgf at 1.0 MPa. The 20 mm window allows the extend stroke to be shortened from 80 mm down to 60 mm, while the retract stroke stays at 80 mm.
An external M20x1.5 threaded stop with a lock nut mechanically limits the outward travel distance, leaving piston area and force unchanged. Deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions. Because it lacks a rod lock, the cylinder cannot hold a load if air pressure drops and will drift.
