About the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-30
The AirTAC ACQJ80X70-30 is a double-acting JIS compact cylinder featuring an external threaded stop that limits the extend end position. You can fine-tune the forward stroke on the machine across a 40 to 70 mm usable range without swapping parts, while the retract stroke stays fixed at its full length. The adjuster mechanism changes travel length only, meaning the piston area and resulting thrust remain completely identical to a standard ACQ unit.
This 80 mm bore actuator delivers 2513.2 N of push force at 0.5 MPa and uses a 25 mm diameter piston rod with a female M16x2.0 end thread. It features fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable pneumatic cushions. Operating speeds span 30 to 500 mm/s, and the body includes magnetic-switch grooves ready for external sensors.

| Series | ACQJ JIS compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Full stroke | 70 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 ACQJ80X70-30 Is Used
Machining Fixture Stops
Dial in the exact clamping reach on CNC machining centers during part changeovers, using the external stop to accommodate varying raw material widths without retooling.
Carton Forming Arms
Adjust the tucking arm extension on packaging lines to handle different box formats on the fly, ensuring precise folding without replacing the actuator.
Assembly Press Positions
Set trial end positions for pressing bearings or pins on automated assembly lines, allowing operators to tweak the 40 to 70 mm stroke window for delicate operations.
Is the Airtac ACQJ80-100 Adjustable Compact Cylinder ACQJ80X70-30 the Right Cylinder?
Choosing this 80 mm bore provides 2513.2 N push at 0.5 MPa, sitting between the smaller 63 mm option (1558.6 N push) and the larger 100 mm variant (3927.0 N push). If your application never requires end-position adjustments, a fixed-stroke ACQ cylinder will deliver the exact same power in a simpler package. When ordering this adjustable model, confirm the 70 mm full stroke, the 30 mm window, the default female rod thread, and whether you need a magnet 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 ACQJ80X70-30 FAQ
The usable extend range is 40 to 70 mm (70 mm full stroke minus the 30 mm window). 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 force is identical to a standard ACQ of this bore.
An external M20x1.5 threaded stop with a lock nut limits the forward stroke, allowing you to shorten the extend length without affecting the retract stroke. The cylinder uses fixed NBR elastomer bumpers at both ends for deceleration rather than adjustable air cushions, so external shock absorbers are recommended for high-energy loads.
