Airtac ACQD Double Acting Compact Cylinder ACQD80X70
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X70 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 70mm 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 ACQD80X70
The AirTAC ACQD80X70 is a double-acting JIS compact cylinder featuring a piston rod extending from both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding equal push and pull forces of 2267.8N at 0.5MPa and 3175N at 0.7MPa. This symmetry is ideal for applications requiring perfectly balanced bidirectional cycles.
Twin rods resist rotation and provide a longer guide length, allowing the unit to carry a tool platform without needing an external anti-rotation guide. The second rod end can drive a sensor flag or secondary load. It uses a fixed NBR elastomer bumper for end-of-stroke deceleration, has PT3/8 ports, and a Ø25mm rod with an M16x2.0 female thread. Note that without external valving, it will not hold position on air loss.
Airtac ACQD Double Acting Compact Cylinder ACQD80X70 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X70 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 70 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 ACQD80X70 Is Used
Twin-Guided Pusher
Drives a wide pallet stopper on a conveyor line, using the dual rods to absorb heavy lateral impact without twisting the tooling.
Symmetric Transfer
Moves a packaging flap folder back and forth across a cartonning machine, relying on equal push and pull forces for consistent cycle timing.
Dual-Station Actuation
Actuates a clamping fixture on an automotive assembly press, using the second rod end to trigger a remote mechanical flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X70 the Right Cylinder?
Delivering 2267.8N both ways at 0.5MPa, this 80mm bore sits between the 63mm (1401.5N) and 100mm (3524.8N) models; choose it when symmetric thrust around 2.2kN is required within a 70mm stroke (max standard 100mm). If your mechanism only needs one-sided push and space is tighter, a single-rod ACQ fits better, while a guided TACQ is preferable for heavy lateral loads. This variant ships without a magnet, uses a female M16x2.0 rod thread, and relies on fixed NBR bumpers rather than adjustable cushions.
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 ACQD80X70 FAQ
The ACQD80X70 generates equal push and pull forces of 2267.8N at 0.5MPa and 3175N at 0.7MPa, with a maximum of 463kgf at 1.0MPa. Push and pull match because the twin rods create equal annular areas on both sides. The maximum standard stroke for this 80mm bore is 100mm.
It uses fixed NBR elastomer bumpers at both ends to absorb end-of-stroke impact, meaning there are no adjustable air cushions. For high-speed approaches, an external shock absorber is recommended. Additionally, it will not hold its load if air pressure is lost; a fail-safe hold requires an external rod lock or pilot-operated check valve.
