Airtac ACQD Double Acting Compact Cylinder ACQD63X40B
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X40B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 40mm 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 ACQD63X40B
The AirTAC ACQD63X40B is a double-acting JIS compact cylinder where a piston rod extends from both ends of the body. Because a rod occupies each chamber, the effective annular area is identical on both sides, yielding equal push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa. This bore uses a PT1/4 port and a Ø20mm rod.
The twin-rod architecture inherently resists rotation and increases the guide length, allowing you to carry a small tool platform without adding an external anti-rotation guide. This specific variant includes male M18x1.5 rod-end threads for direct load coupling, fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration, and integrated sensor grooves. Note that this unit ships without a magnet.
Airtac ACQD Double Acting Compact Cylinder ACQD63X40B Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X40B |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 40 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 ACQD63X40B Is Used
Symmetric Transfer Pusher
Drives a dual-sided pusher arm on a packaging conveyor, utilizing the equal push and pull forces to move cartons smoothly in both directions without torque skew.
Dual-Station Actuation
Uses both male-threaded rod ends to drive two separate pick-and-place heads simultaneously on an assembly machine, cutting cycle time and ensuring parallel movement.
Twin-Guided Platform
Carries a small welding torch platform on an automotive line, relying on the extended guide length and twin rods to prevent tool rotation during vertical positioning.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X40B the Right Cylinder?
When sizing this 63mm bore, dropping to a 50mm bore reduces the equal push/pull force to 824.6N at 0.5MPa, while stepping up to an 80mm bore increases it to 2267.8N. If your application only requires one-sided pushing and does not need anti-rotation, a single-rod ACQ cylinder offers a more compact footprint. Conversely, if your stroke length exceeds the 100mm maximum standard for this series, a guided TACQ cylinder might be necessary. To order, confirm the 40mm stroke, the male M18x1.5 thread option, and the PT1/4 porting.
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 ACQD63X40B FAQ
This cylinder delivers an equal push and pull force of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa, with a maximum load capacity of 286kgf at 1.0MPa. Push and pull forces are identical because the double-rod design creates the same annular area in both chambers. The maximum standard stroke available for this 63mm bore is 100mm.
A plain ACQD does not hold its position upon air loss; the rod drifts and a fail-safe hold requires an external rod lock or pilot-operated check valve. End-of-stroke impacts are absorbed by fixed NBR elastomer bumpers at both ends, which are not adjustable, so external shock absorbers are recommended for high-energy approaches.
