Airtac ACQD Double Acting Compact Cylinder ACQD63X90S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X90S is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 90mm 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 ACQD63X90S
The AirTAC ACQD63X90S is a double-acting JIS compact cylinder featuring twin Ø20 mm rods exiting both ends of the body. Because a rod occupies each chamber, the annular area is identical on extension and retraction, yielding perfectly equal push and pull forces of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa. This symmetry is ideal for applications requiring identical force in both travel directions.
The dual-rod architecture inherently resists rotation and provides an extended guide length, allowing you to mount a tooling platform directly without adding an external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. Fixed NBR elastomer bumpers absorb end-of-stroke impacts, and the built-in -S piston magnet works with reed or solid-state switches in the standard grooves.
Airtac ACQD Double Acting Compact Cylinder ACQD63X90S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X90S |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 90 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 ACQD63X90S Is Used
Symmetric Transfer Arms
Drives a dual-sided pick-and-place arm where the second rod end mounts a mirror flag, keeping cycle forces balanced at 1962.2 N.
Twin-Guided Pusher
Pushes a machined workpiece on a CNC line, using the inherent anti-rotation property of the twin rods to prevent platform yaw.
Dual-Station Actuation
Indexes a tooling rack between two assembly stations, using the equal push and pull areas to maintain consistent timing both ways.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X90S the Right Cylinder?
This 63 mm bore generates 1401.5 N of equal bidirectional force at 0.5 MPa. If your payload is lighter, the 50 mm bore provides 824.6 N, whereas the larger 80 mm bore offers 2267.8 N for heavier demands. The 90 mm stroke sits well within the 100 mm standard limit for this bore. Choose a single-rod ACQ if you only need unidirectional thrust, or a guided TACQ cylinder for extreme lateral loads. Ensure you specify the PT1/4 port and M10x1.5 female 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 ACQD63X90S FAQ
This cylinder provides equal push and pull forces of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa, with a maximum of 286 kgf at 1.0 MPa. Push equals pull because the twin rods create identical annular areas in both chambers. The maximum standard stroke for a 63 mm bore is 100 mm.
No, a plain ACQD does not hold position upon air loss; the rod drifts and the fixed NBR bumper only decelerates near the stroke end. For fail-safe load holding, you must add an external rod lock or a pilot-operated check valve. The twin rods do provide anti-rotation, but not braking.
