Airtac ACQD Double Acting Compact Cylinder ACQD80X125
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X125 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 125mm stroke. The twin rods resist rotation and give equal push and pull force, so it carries and guides a tool platform without a separate anti-rotation guide.

About the Airtac ACQD Double Acting Compact Cylinder ACQD80X125
The AirTAC ACQD80X125 is a double-acting JIS compact cylinder featuring twin Ø25mm rods that exit both ends of the body. Because a rod occupies each chamber, the annular area remains identical in both directions. This yields perfectly equal push and pull forces, delivering 2267.8N at 0.5MPa and 3175N at 0.7MPa without directional imbalance.
This 125mm stroke variant is a made-to-order long-stroke unit, exceeding the 100mm standard maximum for the Ø80 bore. The dual rods provide extended guiding length and inherent anti-rotation properties, eliminating the need for an external non-rotating guide. Deceleration is handled by fixed NBR elastomer bumpers at both ends, while the PT3/8 port accommodates the required pneumatic flow.
Airtac ACQD Double Acting Compact Cylinder ACQD80X125 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X125 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 125 mm |
| Acting type | Double acting, double rod |
| Port size | PT3/8 |
| Rod end thread | M16×2.0 female / M22×1.5 male (B) |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Cushion | Bumper (both ends) |
| Max standard stroke | Up to 100 mm |
Specifications follow the official AirTAC ACQD datasheet. A rod exits both ends, so both directions use the same annular area. Confirm against the product label before installation.
Theoretical Output Force (Ø80mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | 3175 N |
| Max (@1.0 MPa) | 463 kgf | |
Because a rod occupies both chambers, push and pull forces are EQUAL — the annular area applies in each direction. Actual usable force is lower due to friction; size with a safety margin.

Where the Airtac ACQD Double Acting Compact Cylinder ACQD80X125 Is Used
Symmetric Transfer Shuttle
Drives a dual-sided parts shuttle in packaging machinery where equal push and pull forces prevent asymmetric drift during rapid direction reversals.
Twin-Guided Tooling Platform
Carries a machining fixture on a CNC loader, utilizing the two protruding rod ends to resist torsional loads without requiring a separate external guide rail.
Extended Stroke Ejector
Ejects finished castings from a press bed over a 125mm reach, using the extra guide length to maintain platform stability across the long extension.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X125 the Right Cylinder?
Selecting this 80mm bore provides 2267.8N of thrust at 0.5MPa; dropping to a 63mm bore reduces this to 1401.5N, whereas a 100mm bore increases it to 3524.8N. This specific 125mm unit is a long-stroke configuration, extending past the standard 100mm limit into the made-to-order range up to 300mm. If your mechanism only requires force in one direction, a single-rod ACQ cylinder offers a more compact footprint. For applications demanding precise multi-axis stability without external guides, the twin-rod ACQD architecture is the correct fit. Confirm you need the default female M16x2.0 rod-end threads and PT3/8 porting when ordering.
Quick checklist
- ✓ Equal force both ways at your pressure
- ✓ Anti-rotation needed (twin rods)?
- ✓ Both rod ends usable for tooling?
- ✓ 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 Both rods share the load — keep force concentric.
- check Twin rods resist rotation but avoid heavy side load.
- check Handle the C-clip carefully; seat it fully in its groove.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACQD Double Acting Compact Cylinder ACQD80X125 FAQ
The push and pull forces are equal at 2267.8N at 0.5MPa and 3175N at 0.7MPa, with a maximum of 463kgf at 1.0MPa. This equality occurs because the twin rods create the same annular area in both chambers. The 125mm stroke is a made-to-order long-stroke variant, as the standard maximum for this 80mm bore is 100mm.
It uses fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. The body lacks a magnet for sensors. A plain ACQ-type cylinder does not hold its load if air pressure is lost; for fail-safe positioning, you must install an external rod lock or a pilot-operated check valve.
