Airtac ACQD Double Acting Compact Cylinder ACQD63X300B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X300B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm 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 ACQD63X300B
The AirTAC ACQD63X300B is a double-acting JIS compact cylinder featuring twin rods extending from both body ends. Because a rod occupies each chamber, the annular areas match, yielding identical push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa. This 63mm bore unit uses a PT1/4 port and a male M18x1.5 rod thread for direct load coupling.
Designed as a long-stroke made-to-order variant, it exceeds the standard 100mm maximum while retaining the riveted C-clip body. Fixed NBR elastomer bumpers absorb impact at stroke ends rather than adjustable air cushions. The integrated twin-rod guide resists rotation without needing an external guide rail, and the second rod end can drive a second load or sensor flag.
Airtac ACQD Double Acting Compact Cylinder ACQD63X300B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X300B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 300 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 ACQD63X300B Is Used
Symmetric Transfer
Drives a dual-sided pick-and-place handler in packaging machinery, using the equal push and pull forces to move products smoothly in both directions without torque drift.
Twin-Guided Pusher
Executes a 300mm long-stroke ejection cycle on a CNC lathe, relying on the twin rods to prevent platform rotation without adding an external linear guide.
Dual-Station Actuation
Indexes a sorting diverter on a logistics conveyor, using the second protruding rod end to mechanically trigger a downstream pneumatic valve or sensor flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X300B the Right Cylinder?
For lower force needs, the 50mm bore provides 824.6N at 0.5MPa, while the larger 80mm bore offers 2267.8N if your application requires higher thrust. Choose this 63mm long-stroke model when extended travel and equal push/pull forces are required. If you need true fail-safe load holding on air loss, add an external rod lock or pilot-operated check valve, as the fixed bumper only decelerates near stroke end. Confirm the male M18x1.5 thread and PT1/4 port fit your setup.
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 ACQD63X300B FAQ
The ACQD63X300B delivers an equal push and pull force of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa, with a maximum holding force of 286kgf at 1.0MPa. Push and pull forces are identical because the double-rod design creates the same annular area in both chambers. This is a long-stroke variant with a 300mm stroke, exceeding the 100mm standard maximum for a 63mm bore.
It uses fixed NBR elastomer bumpers at both ends to absorb impact, not adjustable air cushions. For high-energy loads, slow the approach or add an external shock absorber. A plain ACQD does not hold its load if air pressure is lost or the valve is centered; the rod will drift. For fail-safe holding, install an external rod lock or pilot-operated check valve.
