Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-50S
The AirTAC ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-50S is a genuine double-acting COMPACT (JIS) cylinder with an EXTERNAL adjustable stop on the extend stroke — a Ø80mm bore and 90mm 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 ACQJ80X90-50S
The AirTAC ACQJ80X90-50S is a double-acting JIS compact cylinder with an external extend-stroke adjuster. A threaded stop and lock nut let you fine-tune the extend end position on the machine, giving a usable extend range of 40 to 90mm. The retract stroke remains completely unaffected.
Because the piston area is unchanged, output force is identical to a standard ACQ of this bore. The cylinder body features fixed NBR elastomer bumpers at both ends and integrated magnetic-switch grooves. The -S option includes a piston magnet compatible with reed or solid-state electronic sensors.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Full stroke | 90 mm |
| Adjuster thread | M20×1.5 |
| Port size | PT3/8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |

| Speed range | 30 – 500 mm/s |
| 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; ACQJ is double-rod, so push is lower than 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 | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
ACQJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod ACQ push of the same bore. Actual usable force is lower due to friction; size with a safety margin.

Where the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-50S Is Used
Machining Fixture Stops
Dial in the exact extend position on CNC loading stations when raw material thickness varies, avoiding the need to swap out hard stops.
Carton Size Changeover
Adapt sealing or forming head heights on packaging lines rapidly for different carton profiles without replacing the actuator.
Press Tonnage Trials
Set precise trial end positions on light assembly presses to verify tooling clearance before locking down the final stroke.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-50S the Right Cylinder?
A fixed-stroke ACQ is sufficient if your end position never varies. When ordering this adjustable unit, confirm the 80mm bore, 90mm full stroke, 50mm window, the -S magnet, and the default female M16x2.0 rod-end thread.
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 ACQJ80X90-50S FAQ
The full stroke is 90mm with a 50mm adjustable window, yielding a usable extend range of 40 to 90mm. The port is PT3/8, the female rod-end thread is M16x2.0, and the external adjuster thread is M20x1.5.
No, the external stop only limits how far the rod extends; the piston area remains the same, so force is identical to a standard ACQ. Deceleration is handled by fixed NBR elastomer bumpers at both ends, not adjustable air cushions. The included -S magnet works with both reed and electronic solid-state switches.
