Airtac ACQD Double Acting Compact Cylinder ACQD63X70S
The AirTAC Airtac ACQD Double Acting Compact Cylinder ACQD63X70S 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 ACQD63X70S
The ACQD63X70S is a double-acting JIS compact cylinder featuring twin rods extending from both ends. Because a rod occupies each chamber, the annular piston area is identical on extension and retraction, yielding an equal 1401.5 N of push and pull force at 0.5 MPa (1962.2 N at 0.7 MPa). This symmetric thrust is ideal for cycles requiring perfectly balanced opposing motions.
Twin Ø20 mm rods inherently resist torsion and lengthen the guide bearing span, allowing a work platform to travel accurately without a separate external guide rail. The second rod end can simultaneously drive a sensor flag or operate a secondary mechanism. Fixed NBR elastomer bumpers absorb impact energy at both stroke extremes, and the -S magnet enables tracking via reed or solid-state switches in the integrated body grooves.
Airtac ACQD Double Acting Compact Cylinder ACQD63X70S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD63X70S |
|---|---|
| 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 ACQD63X70S Is Used
Symmetric Transfer Units
Drives dual-sided conveyor pick-and-place arms in packaging lines where identical push and pull thrust prevents yawing during high-speed product transfers.
Twin-Guided Press Feed
Advances strip material into a stamping press using both rod ends to carry an alignment jig, leveraging the anti-rotation properties to prevent material jamming.
Dual-Station Actuation
Operates two clamps simultaneously from a single compact body in CNC fixture arrays, using the second protruding rod to mount a secondary clamp or sensor flag.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD63X70S the Right Cylinder?
When sizing this 63 mm bore unit, dropping to a 50 mm version reduces the bidirectional thrust to 824.6 N at 0.5 MPa, while stepping up to an 80 mm bore increases it to 2267.8 N. If your application only requires unidirectional thrust and space is tight, a single-rod ACQ cylinder provides greater extension force than retraction. For heavy lateral payloads exceeding the guide capacity, consider a guided TACQ module. Ensure you specify the 70 mm stroke, PT1/4 port, and the default female M10x1.5 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 ACQD63X70S FAQ
It delivers an equal push and pull force of 1401.5 N at 0.5 MPa and 1962.2 N at 0.7 MPa, with a maximum load capacity of 286 kgf at 1.0 MPa. Push and pull forces are identical because the twin rods create equal annular areas in both chambers. The standard stroke maximum for this 63 mm bore is 100 mm, the port size is PT1/4, and the female rod-end thread is M10x1.5.
No, a plain ACQD does not hold position upon air loss; the rod drifts and requires an external rod lock or pilot-operated check valve for fail-safe holding. End-of-stroke impact is managed by fixed NBR elastomer bumpers inside the compact body, which are not adjustable. For high-energy cycles, slow the approach speed or add external shock absorbers.
