Airtac ACQD Double Acting Compact Cylinder ACQD63X40
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X40 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 ACQD63X40
The AirTAC ACQD63X40 is a double-acting JIS compact cylinder featuring twin rods extending from both body ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding exactly equal push and pull forces of 1401.5N at 0.5 MPa. This symmetric thrust is ideal for opposing transfer cycles.
Fixed NBR elastomer bumpers absorb end-of-stroke impact without requiring adjustment. The dual rods prevent platform rotation and extend guide length, while the PT1/4 port and M10x1.5 female rod thread simplify integration. Note that this variant ships without a magnet, though sensor grooves remain machined into the body.
Airtac ACQD Double Acting Compact Cylinder ACQD63X40 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X40 |
|---|---|
| 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 ACQD63X40 Is Used
Symmetric Transfer Arms
Drives a dual-sided pick-and-place arm in packaging machinery where equal push and pull thrust ensures consistent part placement in both travel directions.
Twin-Guided Pusher
Pushes heavy product cartons on a conveyor line, using the inherent anti-rotation properties of the double-rod construction to maintain a perfectly flat contact face.
Dual-Station Actuation
Simultaneously drives a secondary mechanism via the rear rod end on an assembly press, utilizing the second protruding shaft to actuate a valve flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X40 the Right Cylinder?
Choosing this 63mm bore provides 1401.5N of thrust at 0.5 MPa. If your application requires less force, the 50mm bore offers 824.6N. For heavier loads, the 80mm bore yields 2267.8N. If you only need unidirectional thrust, a single-rod ACQ saves space, while a guided TACQ module fits multi-axis tasks. Verify you need the 40mm stroke, female M10x1.5 rod end, and PT1/4 porting before 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 ACQD63X40 FAQ
The cylinder operates at 0.15-1.0 MPa and delivers equal push and pull forces of 1401.5N at 0.5 MPa and 1962.2N at 0.7 MPa, with a maximum holding capacity of 286 kgf at 1.0 MPa. Push and pull forces are identical because the twin rods create equal annular areas on both sides. The maximum standard stroke available for this 63mm bore is 100mm.
The twin-rod design resists rotation and provides long guide length without external guides, but it cannot hold a load if air pressure drops; the shaft will drift. For fail-safe holding, install an external rod lock or pilot-operated check valve. Additionally, the fixed NBR bumpers decelerate the piston near stroke ends but do not act as adjustable air cushions.
