Airtac ACQD Double Acting Compact Cylinder ACQD20X45
The AirTAC ACQD Double Acting Compact Cylinder ACQD20X45 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø20mm bore and 45mm 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 ACQD20X45
The AirTAC ACQD20X45 is a double-acting JIS compact cylinder featuring twin rods that exit from both ends of its riveted C-clip body. Because a piston rod occupies each chamber, the effective annular area remains identical in both directions. This yields equal push and pull forces of 117.8N at 0.5MPa and 164.9N at 0.7MPa, ensuring perfectly symmetric cycle dynamics.
The dual 10mm rods resist torsion and extend the guiding distance, allowing a small tool platform to be carried directly without needing an external anti-rotation guide. Deceleration is handled by fixed TPU elastomer bumpers at each end rather than adjustable air cushions. This specific unit ships without a magnet, yet retains body grooves for mounting external reed or solid-state switches. The second rod end can drive a sensor flag or a secondary load.
Airtac ACQD Double Acting Compact Cylinder ACQD20X45 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD20X45 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø20 mm |
| Stroke | 45 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 ACQD20X45 Is Used
Symmetric Transfer Arms
Drives dual-sided pick-and-place arms in electronics assembly, using the equal push/pull force to maintain balanced positioning throughout the 45mm stroke.
Twin-Guided Pushers
Pushes flat components on a packaging line without twisting, leveraging the inherent torsional resistance of the dual rods to keep the tool plate perfectly aligned.
Dual-Station Actuation
Actuates a secondary mechanism or sensor flag via the rear rod end on a semiconductor handling fixture, saving space by performing two functions from one body.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD20X45 the Right Cylinder?
Delivering 117.8N of force both ways, this 20mm bore unit sits between the 16mm version (75.4N) and the 25mm version (188.9N). If your application requires asymmetric push/pull power, a single-rod ACQ cylinder is a better fit. Choose this double-rod ACQD model when you need built-in anti-rotation and equal forces in a 45mm stroke. Confirm your ordering code specifies the female M5x0.8 rod end and M5x0.8 PT port.
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 ACQD20X45 FAQ
It 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 twin rods create the same annular area in both chambers. The maximum standard stroke available for this 20mm bore is 100mm.
It uses fixed TPU elastomer bumpers at both ends for impact absorption, not adjustable air cushions. Because it lacks a magnet, it cannot trigger internal reed or solid-state sensors. A plain ACQ-type cylinder will not hold its load if air pressure is lost; for fail-safe holding, you must add an external rod lock or pilot-operated check valve.
