Airtac ACQD Double Acting Compact Cylinder ACQD12X40B
The AirTAC ACQD Double Acting Compact Cylinder ACQD12X40B is a genuine double-acting COMPACT (JIS) cylinder with a piston rod out BOTH ends — a Ø12mm bore and 40mm 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 ACQD12X40B
The AirTAC ACQD12X40B is a double-acting JIS compact cylinder featuring twin Ø6mm rods exiting both ends. Because a rod occupies each chamber, the annular area is identical in both directions, yielding exactly 42.4N of force at 0.5MPa and 59.4N at 0.7MPa for both extension and retraction. This bore 12 unit includes a male M5x0.8 rod-end thread for direct load coupling.
The dual-rod architecture inherently resists rotation and extends guide length, eliminating the need for a separate external anti-rotation guide on small tooling platforms. 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 unit ships without a magnet. Operating pressure spans 0.15-1.0MPa, and the standard M5x0.8 port uses a PT tapered thread form.
Airtac ACQD Double Acting Compact Cylinder ACQD12X40B Technical Specifications

| Stroke | 40 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 ACQD12X40B Is Used
Twin-Guided Pick & Place
Drives a small pneumatic gripper on a chip-handling machine, using the dual rods to maintain parallelism without a separate guide rail.
Symmetric Component Transfer
Shuttles light electronic parts between two stations, leveraging the equal push and pull annular areas for consistent cycle timing.
Dual-Station Actuation
Powers a tiny testing fixture where the second rod end mounts a mechanical flag to trip an external limit switch.
Is the Airtac ACQD Double Acting Compact Cylinder ACQD12X40B the Right Cylinder?
Select this 12mm bore, 40mm stroke model when a compact footprint requires symmetric push and pull cycles without rotational play. If your mechanism needs less force, a single-rod ACQ might suffice, but it will not provide equal bidirectional thrust. If your application exceeds the 9kgf maximum capacity, stepping up to the 16mm bore offers 105.6N at 0.7MPa. Keep in mind this variant uses a male M5x0.8 rod thread; specify the female thread version if your tooling requires a different mounting interface.
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 ACQD12X40B FAQ
The push and pull forces are equal at 42.4N (0.5MPa) and 59.4N (0.7MPa), with a maximum capacity of 9kgf at 1.0MPa. The maximum standard stroke available for this 12mm bore is 50mm.
The twin rods resist rotation and extend guide length. It uses fixed TPU elastomer bumpers at both ends, not adjustable air cushions. A plain ACQD does not hold position on air loss; install an external rod lock or pilot-operated check valve for fail-safe load holding.
