Airtac ACQD Double Acting Compact Cylinder ACQD63X250B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X250B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm 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 ACQD63X250B
The AirTAC ACQD63X250B is a double-acting JIS compact cylinder featuring a 63mm bore and an extended 250mm stroke. Because twin rods protrude from both body ends, the effective annular area remains identical in either travel direction. This architecture yields perfectly balanced thrust, generating 1401.5N at 0.5MPa and 1962.2N at 0.7MPa for both extension and retraction. A male M18x1.5 thread outfits the rod end for direct load coupling.
This made-to-order long-stroke variant bypasses the standard 100mm travel limit for this bore size, utilizing the extended range up to 300mm. The dual rods supply extended guide length and inherent anti-rotation properties, eliminating the need for a separate external guide in many setups. Deceleration relies on fixed NBR elastomer bumpers at each end rather than adjustable air cushions. The unit lacks a piston magnet, though the body retains standard sensor grooves for adding external reed or solid-state switches.
Airtac ACQD Double Acting Compact Cylinder ACQD63X250B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X250B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 250 mm |
| Acting type | Double acting, double rod |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 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 (Ø63mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 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 ACQD63X250B Is Used
Symmetric Transfer Arms
Drives dual-sided pick-and-place arms in packaging machinery where equal push and pull forces maintain balanced kinetic energy during product transfer.
Twin-Guided Pushers
Actuates long-stroke material pushers on conveyor lines; the dual rods resist torsional twist without needing a bulky external linear guide.
Dual-Station Actuation
Powers dual-station clamping fixtures in automated woodworking, using the second rod end to mirror clamping force or mount a mechanical flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X250B the Right Cylinder?
When sizing this actuator, stepping down to a 50mm bore yields 824.6N at 0.5MPa, while stepping up to an 80mm bore provides 2267.8N at 0.5MPa. Choose this 63mm option for symmetric push/pull cycles requiring roughly 1.4kN of force. If your application only needs one-way thrust, a single-rod ACQ cylinder offers a more compact footprint. For heavy lateral loads over this 250mm span, a guided TACQ unit might provide superior bearing support. To order, confirm the PT1/4 port, the male M18x1.5 rod thread, and the extended travel requirement.
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 ACQD63X250B FAQ
This cylinder provides equal push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa, with a maximum holding capability of 286kgf at 1.0MPa. Push equals pull because the double-rod design creates identical annular piston areas on both sides. The 250mm stroke is a made-to-order long-stroke configuration, exceeding the 100mm standard maximum for this 63mm bore.
End-of-stroke deceleration relies on fixed NBR elastomer bumpers, not adjustable air cushions; for high-energy loads an external shock absorber is recommended. Additionally, a plain ACQD cylinder does not hold position if air pressure drops or a valve is centered, so an external rod lock or pilot-operated check valve is required for fail-safe load holding.
