Airtac ACQD Double Acting Compact Cylinder ACQD63X25B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X25B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 25mm 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 ACQD63X25B
The AirTAC ACQD63X25B is a double-acting JIS compact cylinder featuring twin rods that exit both ends. Because a rod occupies each chamber, the effective annular area is identical in both directions, yielding perfectly equal push and pull forces of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa. This symmetric thrust is ideal for cycles requiring identical advancing and retracting power.
The dual shafts resist rotation and provide an extended guide length, allowing a tool platform to be carried directly without needing an external anti-rotation guide. This unit includes a male M18x1.5 rod-end thread for direct load coupling. It uses fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. The body retains magnetic-switch grooves, but this specific configuration ships without a piston magnet.
Airtac ACQD Double Acting Compact Cylinder ACQD63X25B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X25B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 25 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 ACQD63X25B Is Used
Symmetric Transfer Pusher
Drives a dual-sided pusher plate on packaging machinery where the second rod end simultaneously triggers a reed switch flag to confirm cycle completion.
Twin-Guided Stamping Platform
Carries a small stamping head in an electronics factory, relying on the dual rods to prevent torsion and maintain tool alignment without a separate guide.
Dual-Station Actuation
Powers a two-sided clamping fixture on an automotive parts assembly line, using the equal 1962.2N force to secure components identically in both directions.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X25B the Right Cylinder?
Selecting this 63mm bore with a 25mm stroke provides 1401.5 N of equal bidirectional force at 0.5 MPa. If your application requires less force, the 50mm bore yields 824.6 N, whereas stepping up to an 80mm bore provides 2267.8 N. If your mechanism already has an external guide rail and only needs unidirectional thrust, a single-rod ACQ cylinder is a simpler choice. For applications needing precise non-rotation over a longer span, a guided TACQ series might fit better. Confirm your ordering essentials: this ACQD63X25B variant includes the male M18x1.5 rod thread and PT1/4 port.
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 ACQD63X25B FAQ
The push and pull forces are equal at 1401.5 N @0.5 MPa and 1962.2 N @0.7 MPa, with a maximum holding capacity of 286 kgf at 1.0 MPa. Push equals pull because the twin rods create identical annular areas on both sides. The operating pressure is 0.15-1.0 MPa, and the maximum standard stroke available for this 63mm bore is 100mm.
No, a plain ACQD does not hold its load on air loss; the rod drifts and you must add an external rod lock or pilot-operated check valve for fail-safe holding. For motion control, it uses fixed NBR elastomer bumpers at both ends to decelerate the piston near stroke end, rather than an adjustable air cushion. For high-speed cycles, you should slow the approach or add an external shock absorber.
