Airtac ACQD Double Acting Compact Cylinder ACQD80X250
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD80X250 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø80mm bore and 250mm 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 ACQD80X250
The AirTAC ACQD80X250 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, delivering an equal push and pull force of 2267.8N at 0.5MPa and 3175N at 0.7MPa. The twin rods resist rotation and provide a longer guide length, allowing you to carry a tool platform without needing an external anti-rotation guide.
This 80mm bore variant features a Ø25mm rod, female M16x2.0 rod-end threads, and PT3/8 ports. It uses fixed NBR elastomer bumpers at each end for end-of-stroke deceleration rather than adjustable air cushions. The 250mm stroke is a made-to-order long-stroke configuration exceeding the 100mm standard maximum for this bore size. Please note this specific configuration ships without a piston magnet, although the body retains sensor grooves for adding external switches if needed later. A plain cylinder does not hold its load on air loss; pair it with an external rod lock or pilot check valve for fail-safe holding.
Airtac ACQD Double Acting Compact Cylinder ACQD80X250 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD80X250 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 250 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 ACQD80X250 Is Used
Twin-Guided Pusher
Drives a wide format material pusher on a woodworking router, using the dual rods to prevent platform twisting without installing an external linear guide.
Symmetric Transfer
Executes balanced push-and-pull transfer cycles on an automotive stamping line, leveraging the equal 3175N force to move pallets identically in both directions.
Dual-Station Actuation
Powers a dual-station clamping fixture on a packaging machine, using the second protruding rod end to trigger a physical flag or drive a secondary mechanism simultaneously.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD80X250 the Right Cylinder?
For sizing, the neighboring 63mm bore yields 1401.5N at 0.5MPa, while the larger 100mm bore provides 3524.8N at 0.5MPa. If your application requires asymmetric push and pull forces, a single-rod ACQ cylinder is a better fit. If your load demands extreme rigidity against lateral deflection over this long 250mm stroke, consider a guided TACQ cylinder. When ordering, verify your porting (PT3/8), the female M16x2.0 rod-end threads, and the 250mm made-to-order stroke requirement. For high-speed cycles, add an external shock absorber since the NBR bumpers are fixed and non-adjustable.
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 ACQD80X250 FAQ
The push and pull forces are equal at 2267.8N @0.5MPa and 3175N @0.7MPa, with a maximum of 463kgf @1.0MPa. The equal force occurs because the double-rod design creates the same annular area in both chambers. The 250mm stroke is a made-to-order long-stroke variant, as the standard maximum for an 80mm bore is 100mm.
The twin rods resist rotation and add guide length. This specific model lacks a piston magnet but retains body grooves for mounting external reed or solid-state switches. It uses fixed NBR bumpers, not adjustable cushions. It will not hold a load if air pressure is lost; an external rod lock or pilot-operated check valve is required for fail-safe holding.
