Airtac ACQD Double Acting Compact Cylinder ACQD12X45
The AirTAC ACQD Double Acting Compact Cylinder ACQD12X45 is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø12mm 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 ACQD12X45
The AirTAC ACQD12X45 is a 12mm JIS compact double-acting cylinder featuring a 6mm rod exiting both ends. Because the twin rods occupy both chambers, the annular area remains identical in each direction. This yields an equal push and pull force of 42.4N at 0.5MPa and 59.4N at 0.7MPa, enabling perfectly symmetric cycles without force mismatch.
The dual shafts inherently resist rotation and provide a longer guide length, allowing you to mount a small tool platform directly without needing an external anti-rotation guide. It uses a fixed TPU elastomer bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion. The body retains magnetic-switch grooves, though this specific configuration ships without a magnet. Operating pressure spans 0.15-1.0MPa, and the standard M5x0.8 port ensures rapid pneumatic response.
Airtac ACQD Double Acting Compact Cylinder ACQD12X45 Technical Specifications
| Model | Airtac ACQD Double Acting Compact Cylinder ACQD12X45 |
|---|---|
| Series | ACQD JIS compact double-rod cylinder |
| Bore size | Ø12 mm |
| Stroke | 45 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 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 50 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 (Ø12mm — equal both ways)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 42 N | 42 N |
| 0.7 MPa | 59 N | 59 N |
| Max (@1.0 MPa) | 9 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 ACQD12X45 Is Used
Twin-Guided Pick-and-Place
Mounts a small gripper directly to the second rod end on a chip-handling robot, using the extended guide length to prevent jaw twist without a separate guide.
Symmetric Wire Feeder
Drives a wire spooling carriage in a cable manufacturing machine where the identical 42.4N push and pull force guarantees consistent tension in both travel directions.
Dual-Station Ejector
Actuates a tiny electronic component ejector on a PCB assembly line, using the opposite rod end to trigger a physical flag for a home position sensor.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD12X45 the Right Cylinder?
This 12mm bore delivers 42.4N of force both ways across its 45mm stroke. If you need slightly less force, the smaller 12mm bore is the starting point of the series, so the next logical step up is the 16mm bore providing 75.4N at 0.5MPa. If your application requires true fail-safe load holding on air loss, remember a plain ACQD drifts; you must add an external rod lock or pilot check valve. To order, confirm the 45mm stroke, the default female M3x0.5 rod-end thread, and the standard PT M5x0.8 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 ACQD12X45 FAQ
The cylinder provides an equal push and pull force of 42.4N at 0.5MPa and 59.4N at 0.7MPa, with a maximum force of 9kgf at 1.0MPa. Push and pull are equal because the dual rods create the same annular piston area in both chambers. The maximum standard stroke available for this 12mm bore is 50mm.
No, a plain ACQD cannot hold its position on air loss because the fixed TPU elastomer bumper only decelerates the rod near the stroke end. For fail-safe load holding, you must install an external rod lock or a pilot-operated check valve.
