Airtac ACQD Double Acting Compact Cylinder ACQD80X90
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X90 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 90mm 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 ACQD80X90
The AirTAC ACQD80X90 is a JIS double-acting compact cylinder engineered with twin rods exiting both ends. Because a piston rod occupies each chamber, the effective annular area remains identical in both directions, yielding perfectly equal push and pull forces of 2267.8N at 0.5MPa and 3175N at 0.7MPa. This symmetric thrust is ideal for applications requiring balanced bi-directional cycles. The Ø25mm rods provide extended guide length and inherent anti-rotation properties, eliminating the need for a separate external guide in heavy-duty tooling platforms.
Built with a fixed NBR elastomer bumper at each end, it absorbs end-of-stroke impact without relying on adjustable air cushions. The body features magnetic-switch grooves, though this specific configuration ships without a magnet. Operating at pressures from 0.15-1.0MPa with PT3/8 ports, it supports speeds of 30-500mm/s. Note that a plain compact cylinder does not hold its load on air loss; for fail-safe holding, an external rod lock or pilot-operated check valve is required.
Airtac ACQD Double Acting Compact Cylinder ACQD80X90 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X90 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 90 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 ACQD80X90 Is Used
Twin-Guided Pusher
Drives a heavy-duty stamping or press die set where the dual rods prevent platform twisting under high offset loads.
Symmetric Transfer
Powers a dual-station pallet transfer system in packaging machinery, utilizing equal push and pull forces for consistent cycle timing.
Dual-Station Actuation
Actuates a secondary mechanism or sensor flag from the opposite rod end on an automotive assembly line without extra external linkages.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X90 the Right Cylinder?
Selecting this 80mm bore with a 90mm stroke provides a maximum 463kgf at 1.0MPa, fitting just below the 100mm bore (3524.8N @0.5MPa) and above the 63mm bore (1401.5N @0.5MPa). If your mechanism only requires force in one direction, a single-rod ACQ cylinder offers a more compact footprint. For applications demanding extreme lateral load support without rotational resistance, a guided TACQ cylinder might be a better fit. Ensure you specify the default female M16x2.0 rod-end thread and PT3/8 port 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 ACQD80X90 FAQ
The ACQD80X90 delivers an equal push and pull force of 2267.8N at 0.5MPa and 3175N at 0.7MPa, with a maximum capacity of 463kgf at 1.0MPa. Push and pull forces are identical because the twin rods create the same annular area in both chambers. The maximum standard stroke available for this 80mm bore is 100mm.
The twin Ø25mm rods exiting both ends resist rotation and provide longer guide support. It uses fixed NBR elastomer bumpers at each end for impact absorption, not adjustable air cushions. A plain ACQD does not hold position if air pressure is lost; for fail-safe load holding, you must install an external rod lock or pilot-operated check valve.
