Airtac ACQD Double Acting Compact Cylinder ACQD63X70
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X70 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø63mm bore and 70mm 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 ACQD63X70
The AirTAC ACQD63X70 is a double-acting JIS compact cylinder featuring twin rods extending from both ends. Because a rod occupies both internal chambers, the annular area is identical in each direction, yielding perfectly equal push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa. This symmetric thrust is ideal for applications requiring consistent motion in both cycle directions.
The dual-rod architecture inherently resists rotation and extends the guide length, allowing you to mount a tool platform directly without adding an external anti-rotation guide. The second rod end can drive a sensor flag or a secondary load. It features a 63mm bore, a 20mm rod diameter, and fixed NBR elastomer bumpers at both ends for end-of-stroke deceleration.
Airtac ACQD Double Acting Compact Cylinder ACQD63X70 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X70 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø63 mm |
| Stroke | 70 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 ACQD63X70 Is Used
Twin-Guided Pusher
Drives a wide format pusher bar in packaging machinery, using both rods to keep the plate perfectly parallel without twisting under asymmetric loads.
Symmetric Transfer Unit
Executes balanced pick-and-place transfers on an assembly line, leveraging the equal 1401.5N push and pull forces to maintain stable acceleration in both directions.
Dual-Station Actuation
Powers a dual-station clamping fixture in electronics manufacturing, using the second protruding rod end to mechanically trigger a remote position flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X70 the Right Cylinder?
At 0.5MPa this 63mm bore generates 1401.5N both ways; if your load is lighter, the 50mm bore provides 824.6N, while the heavier 80mm bore offers 2267.8N. This 70mm stroke sits well within the 100mm maximum standard travel for this bore. If your layout only needs force in one direction, a single-rod ACQ cylinder is simpler, but if you need non-rotating guidance, this ACQD is optimal. It ships with a female M10x1.5 rod end and PT1/4 port; note this specific unit lacks the -S magnet.
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 ACQD63X70 FAQ
The ACQD63X70 delivers equal push and pull forces of 1401.5N at 0.5MPa and 1962.2N at 0.7MPa, with a maximum rated force of 286kgf at 1.0MPa. Push and pull forces are identical because the double-rod design creates the same annular area in both directions. The maximum standard stroke available for this 63mm bore is 100mm.
It uses fixed NBR elastomer bumpers at both ends to absorb shock near stroke completion; it does not have adjustable air cushions. Note that a plain ACQD does not hold its load if air pressure is lost or the valve is centered, so an external rod lock or pilot-operated check valve is required for fail-safe positioning.
