Airtac ACQD Double Acting Compact Cylinder ACQD20X80
The AirTAC ACQD Double Acting Compact Cylinder ACQD20X80 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø20mm bore and 80mm 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 ACQD20X80
The AirTAC ACQD20X80 is a double-acting JIS compact cylinder featuring twin Ø10mm rods that exit both ends of its riveted C-clip body. Because a rod occupies each chamber, the annular area remains identical on both sides, yielding perfectly equal push and pull forces of 117.8N at 0.5MPa (164.9N at 0.7MPa). This symmetry is ideal for applications requiring consistent bi-directional thrust without force differential drift.
Beyond equal force, the dual-rod geometry inherently resists rotation and extends the guide length, allowing a small tool platform to be carried directly without needing an external anti-rotation guide. The second rod end can simultaneously drive a secondary load or mount a sensor flag. Deceleration relies on fixed TPU elastomer bumpers at each end rather than adjustable air cushions. Note that this specific configuration lacks the -S magnet, though the body retains sensor grooves for adding external switches.
Airtac ACQD Double Acting Compact Cylinder ACQD20X80 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD20X80 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 80 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M5×0.8 female / M8×1.25 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 (Ø20mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 118 N | 118 N |
| 0.7 MPa | 165 N | 165 N |
| Max (@1.0 MPa) | 24 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 ACQD20X80 Is Used
Symmetric Transfer Pusher
Drives a bi-directional parts shuttle in electronics assembly, utilizing the equal 117.8N push and pull forces to maintain consistent timing during forward and return strokes.
Twin-Guided Tool Platform
Carries a small pick-and-place head on both rod ends in a packaging machine, leveraging the extended guide length to prevent platform rotation without adding an external guide rail.
Dual-Station Actuation
Actuates two separate clamps simultaneously from a single 20mm bore body in a machining fixture, using the second protruding rod end to drive a secondary mechanism.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD20X80 the Right Cylinder?
Providing 117.8N of force both ways at 0.5MPa, this 20mm bore sits neatly between the 16mm (75.4N) and 25mm (188.9N) sizes for your 80mm stroke requirement. If your mechanism only needs thrust in one direction and force imbalance is acceptable, a single-rod ACQ20X80 offers a more compact footprint. If your load demands high lateral rigidity and true anti-twist guidance beyond the twin rods, a guided slide cylinder like the TACQ series might be a better fit. When ordering, confirm the default female M5x0.8 rod-end thread, M5x0.8 port, and that no magnet is included.
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 ACQD20X80 FAQ
The ACQD20X80 delivers an equal push and pull force of 117.8N at 0.5MPa and 164.9N at 0.7MPa, with a maximum capacity of 24kgf at 1.0MPa. Push and pull forces are identical because the double-rod design creates the same annular piston area in both chambers. The maximum standard stroke available for this 20mm bore is 100mm.
No, a plain ACQD does not hold its position when air is lost; the rod will drift and you must add an external rod lock or pilot-operated check valve for fail-safe load holding. For motion control, impact is absorbed by fixed TPU elastomer bumpers at both stroke ends, which are not adjustable, so high-energy cycles may require slowing the approach speed.
