Airtac ACQD Double Acting Compact Cylinder ACQD63X300S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X300S 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 ACQD63X300S
The AirTAC ACQD63X300S is a double-acting JIS compact cylinder featuring a 63mm bore and an extended 300mm stroke. Because twin rods exit both ends, the annular piston area remains identical in either direction, yielding exactly 1401.5N at 0.5MPa and 1962.2N at 0.7MPa for both extension and retraction. This symmetry prevents the force differential found in single-rod units.
Built with a fixed NBR elastomer bumper at each end rather than adjustable air cushions, it handles 30-500mm/s speeds within a -20 to +70C environment. The integrated -S piston magnet supports both reed and solid-state electronic sensors via the body grooves. As a 300mm stroke exceeds the 100mm standard maximum for this bore, it is supplied as a long-stroke made-to-order variant.
Airtac ACQD Double Acting Compact Cylinder ACQD63X300S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X300S |
|---|---|
| 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 ACQD63X300S Is Used
Twin-Guided Pusher
Drives a wide format carton reject gate on a packaging line, using the dual rods to resist torsional twisting without needing an external linear guide.
Symmetric Transfer
Powers a pick-and-place beam in electronics assembly where the second rod end mounts a flag for a solid-state sensor, tracking position from the opposite side.
Dual-Station Actuation
Indexes a 300mm shuttle table between two machining stations, leveraging the equal push and pull forces to maintain consistent cycle timing in both directions.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X300S the Right Cylinder?
Selecting this 63mm bore provides 1401.5N of bidirectional thrust at 0.5MPa; dropping to a 50mm bore yields 824.6N, while stepping up to 80mm offers 2267.8N. If your application only requires one-sided actuation without anti-rotation, a standard single-rod ACQ cylinder is more compact. For standard 100mm strokes or less, choose the standard ACQD63 variant. Confirm the PT1/4 port, Ø20mm rods, and female M10x1.5 rod-end threads for your mounting hardware.
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 ACQD63X300S FAQ
It generates 1401.5N at 0.5MPa and 1962.2N at 0.7MPa, with a maximum holding capacity of 286kgf at 1.0MPa. Push and pull forces are equal because the twin rods occupy both chambers, creating the same annular area in either direction. The 300mm stroke is a made-to-order long-stroke variant, exceeding the 100mm standard maximum for this 63mm bore.
No, a plain ACQD does not maintain position upon air loss; the fixed NBR bumpers only decelerate the piston near the stroke ends. For fail-safe load holding, an external rod lock or pilot-operated check valve must be added to the pneumatic circuit.
