About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-30
The AirTAC ACQJ80X90-30 is a double-acting JIS compact cylinder featuring an external adjustable extend stop. A threaded rod-end screw with a lock nut lets you fine-tune the extend end position on the machine, providing a usable extend range of 60 to 90 mm without changing parts. The retract stroke remains completely unaffected.
Because the piston area is unchanged, output force is identical to a standard ACQ of the same bore. At 0.5 MPa, it delivers 2513.2 N of push force and 2267.8 N of pull force. The unit features a 25 mm piston rod, a PT3/8 port, and fixed elastomer bumpers at both ends for end-of-stroke deceleration.

| 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; 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 ACQJ80X90-30 Is Used
Machining Fixture Stops
Dial in the exact extend position of a clamping mechanism on a CNC mill during setup, allowing 60 to 90 mm of travel to accommodate different part heights without swapping cylinders.
Product Changeover Guides
Reposition a pneumatic diverter or end-stop on a packaging line within the 30 mm window to handle new carton sizes quickly, keeping the retract stroke consistent.
Prototype Press End-Points
Test various engagement depths on a light assembly press by turning the external M20x1.5 adjuster, finding the optimal contact point before finalizing the mechanical design.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X90-30 the Right Cylinder?
When sizing this 80 mm bore, note that a 63 mm bore yields 1558.6 N push at 0.5 MPa, while a 100 mm bore provides 3927.0 N. If your machine never requires end-position adjustments, a fixed-stroke ACQ cylinder is sufficient. To order, confirm the 80 mm bore, 90 mm full stroke, 30 mm adjustable window, female M16x2.0 rod-end thread, and whether you require the -S magnet option for position 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 ACQJ80X90-30 FAQ
This double-acting cylinder has a 90 mm full stroke with a 30 mm adjustable window, giving a usable extend range of 60 to 90 mm. 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 retract stroke remains fixed at 90 mm.
The external threaded stop with a lock nut physically limits how far the rod extends, shortening the stroke by up to 30 mm. It does not change the piston area, so force remains identical to a standard ACQ. The cylinder uses fixed elastomer bumpers for deceleration, not adjustable air cushions. Note that this model ships without a sensor magnet.
