Airtac ACQD Double Acting Compact Cylinder ACQD63X35
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X35 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 35mm 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 ACQD63X35
The ACQD63X35 is a double-acting JIS compact cylinder featuring twin piston rods that exit from both ends of the body. Because a rod occupies each working chamber, the annular area remains identical in both directions, yielding equal push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa. This symmetric thrust is ideal for applications requiring consistent cycling in both directions.
The dual-rod architecture inherently resists rotation and provides an extended guide length, allowing you to mount a tooling platform directly without needing an external non-rotation guide. The second rod end can simultaneously drive a secondary load or flag. It features a 20mm rod diameter, PT1/4 porting, and fixed NBR elastomer bumpers at both ends to soften end-of-stroke impacts.
Airtac ACQD Double Acting Compact Cylinder ACQD63X35 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X35 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 35 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 ACQD63X35 Is Used
Symmetric Transfer Shuttle
Drives a dual-sided parts shuttle in packaging machinery, utilizing the equal push and pull thrust to maintain consistent cycle times in both directions.
Twin-Guided Tooling Platform
Carries a precision pick-and-place head on a printed circuit board assembly line without needing an external guide, relying on the twin rods to prevent deflection.
Dual-Station Actuation
Powers a dual-station clamping fixture in an automotive components plant, using the second protruding rod end to trigger a mechanical flag or secondary process.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X35 the Right Cylinder?
Delivering 1401.5N of force both ways at 0.5MPa, this 63mm bore unit sits between the 50mm bore (824.6N) and the 80mm bore (2267.8N) options. If your application only requires unidirectional thrust and lacks a rigid tooling plate, a standard single-rod ACQ cylinder may suffice and save space. However, for twin-guided pushing or symmetric transfer where rotation must be prevented, this double-rod configuration is the correct choice. Confirm your requirements for the 35mm stroke, PT1/4 porting, and the default female M10x1.5 rod-end thread 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 ACQD63X35 FAQ
The push and pull forces are equal at 1401.5N at 0.5MPa and 1962.2N at 0.7MPa, with a maximum holding capability of 286kgf at 1.0MPa. The standard maximum stroke available for this 63mm bore is 100mm. Operating pressure ranges from 0.15-1.0MPa.
No, a plain ACQD does not hold its load on air loss; the rod will drift and the fixed NBR elastomer bumper only decelerates near the stroke end. For fail-safe holding, an external rod lock or pilot-operated check valve is required. The bumpers are fixed and not adjustable, so external shock absorbers are recommended for high-speed approaches.
