Airtac ACQD Double Acting Compact Cylinder ACQD20X80S
The AirTAC ACQD Double Acting Compact Cylinder ACQD20X80S 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 ACQD20X80S
The AirTAC ACQD20X80S is a double-acting JIS compact cylinder featuring twin Ø10mm rods that exit both ends of the body. Because a rod occupies each chamber, the annular area is identical in both directions, yielding perfectly equal push and pull forces of 117.8N at 0.5MPa and 164.9N at 0.7MPa. This symmetry is ideal for applications requiring consistent bi-directional thrust without force drop on the return stroke.
The dual-rod layout inherently resists rotation and provides a longer guide length, allowing you to carry a small tool platform directly without needing an external anti-rotation guide. The second rod end can simultaneously drive a sensor flag or a secondary load. This 80mm stroke unit includes the -S piston magnet for position detection via reed or electronic solid-state switches, and relies on fixed TPU elastomer bumpers at both ends rather than adjustable air cushions.
Airtac ACQD Double Acting Compact Cylinder ACQD20X80S Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD20X80S |
|---|---|
| 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 ACQD20X80S Is Used
Symmetric Transfer Pusher
Drives a parts shuttle back and forth across a conveyor with identical 117.8N thrust in both directions, ensuring consistent cycle timing on packaging lines.
Twin-Guided Pick & Place
Carries a small gripper platform directly on the dual rods without an external guide, resisting torsional deflection during rapid vertical placement in electronics assembly.
Dual-Station Actuation
Uses the second protruding rod end to trigger a mechanical flag or secondary stop on a machining center while the primary end performs the main clamping action.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD20X80S the Right Cylinder?
Selecting this 20mm bore provides 117.8N of equal bidirectional force at 0.5MPa. Stepping down to a 16mm bore reduces the output to 75.4N, while moving up to a 25mm bore increases it to 188.9N. If your mechanism only requires force in one direction and lacks a side load, a single-rod ACQ cylinder may suffice. However, for twin-guided pushing or symmetric transfer tasks, this ACQD configuration is optimal. Confirm your ordering essentials: the standard M5x0.8 port, female M5x0.8 rod-end threads, and the 80mm stroke which is well within the 100mm maximum standard for this bore.
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 ACQD20X80S FAQ
It delivers an equal push and pull force of 117.8N at 0.5MPa and 164.9N at 0.7MPa, with a maximum holding capacity of 24kgf at 1.0MPa. Push and pull forces are identical because the twin rods create the same annular area in both chambers. The maximum standard stroke for a 20mm bore is 100mm, and this unit features an 80mm stroke. The piston rod is Ø10mm with a female M5x0.8 rod-end thread and an M5x0.8 pneumatic port.
It uses fixed TPU elastomer bumpers at both ends for end-of-stroke deceleration, not adjustable air cushions, so external shock absorbers may be needed for high-energy loads. The -S option includes a piston magnet compatible with both reed and electronic solid-state switches. Note that a plain ACQD does not hold its load if air pressure is lost; for fail-safe holding, an external rod lock or pilot-operated check valve is required.
