Airtac ACQD Double Acting Compact Cylinder ACQD80X300S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X300S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 300mm 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 ACQD80X300S
The AirTAC ACQD80X300S is a double-acting JIS compact cylinder featuring twin rods extending from both body ends. Because a piston shaft occupies each chamber, the effective annular area is identical in both directions, yielding equal push and pull forces of 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa. This 80mm bore configuration provides a maximum holding capability of 463 kgf at 1.0 MPa.
Featuring a 300mm stroke, this unit is a made-to-order long-stroke variant exceeding the 100mm standard maximum for this bore size. The dual-shaft design inherently resists rotation and extends guide length, allowing a tool platform to be carried without needing an external anti-rotation guide. It uses fixed NBR elastomer bumpers for end-of-stroke deceleration rather than adjustable air cushions, and the included -S magnet works with reed or solid-state sensors.
Airtac ACQD Double Acting Compact Cylinder ACQD80X300S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X300S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 300 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 ACQD80X300S Is Used
Symmetric Transfer Pusher
Drives a long-travel 300mm product pusher on a packaging conveyor where equal push and pull forces prevent stalling during return strokes.
Dual-Station Actuation
Simultaneously operates two synchronized clamps from opposite ends on an automotive welding fixture, utilizing the twin rod ends.
Twin-Guided Tool Platform
Carries a heavy 80mm boring head between machining stations without an external guide rail, relying on the anti-rotation dual rods.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X300S the Right Cylinder?
Selecting this 80mm bore model provides 2267.8 N of equal bidirectional force at 0.5 MPa; dropping to a 63mm bore reduces this to 1401.5 N, while stepping up to a 100mm bore increases it to 3524.8 N. If your application only needs standard lengths up to 100mm, the regular ACQD80 stock is more compact. For pure linear transfer without rotational resistance, a single-rod ACQ or a guided TACQ unit might be simpler. Verify your porting (PT3/8) and female rod-end threads (M16x2.0) during 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 ACQD80X300S FAQ
It delivers equal push and pull forces of 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa, with a maximum holding force of 463 kgf at 1.0 MPa. Push equals pull because the twin rods create identical annular areas in both chambers. The 300mm stroke is a made-to-order long-stroke variant, exceeding the 100mm standard maximum for this 80mm bore.
It uses fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration, not adjustable air cushions. For high-speed or high-energy loads, an external shock absorber or slower approach is recommended. A plain ACQD does not hold its load when air is lost; for fail-safe holding, an external rod lock or pilot-operated check valve is required.
